Top vs Side Radiator in a Panoramic PC Case

For most gaming builds, I would mount the AIO radiator at the top as exhaust and use the side and bottom fans as intake.

A side-mounted radiator configured as intake can deliver cooler air to the radiator and reduce CPU or coolant temperature, but it also pushes radiator-heated air into the main chamber. In a high-power gaming PC, that trade can raise GPU, memory, VRM, and SSD temperatures.

In a panoramic chassis, the side fan wall, bottom intake, top exhaust, GPU cooler, radiator resistance, dust filters, cable chamber, and pump position all interact, so a layout that wins a five-minute CPU test can lose badly during a 45-minute mixed gaming load.

The Best AIO Radiator Placement Depends on What You Are Cooling

The hard truth is that there is no universally “best” AIO radiator placement. There is only the best placement for a specific case, component combination, workload, room temperature, noise target, and fan configuration.

Modern hardware makes that distinction expensive to ignore. NVIDIA lists the GeForce RTX 5090 at 

, while Intel lists the Core Ultra 9 285K at 

 before the motherboard, pump, memory, storage, and power-conversion losses are counted.

A 360 mm radiator does not eliminate that heat. It moves CPU heat from the cold plate to the coolant, from the coolant to the radiator, and from the radiator into whichever air stream passes through it.

Where that warmed air goes is the entire argument.

My default recommendations are straightforward:

Before selecting the case itself, read AceGeek’s guide to 

. The radiator decision should be made alongside GPU clearance, bottom ventilation, fan thickness, tube routing, and cable access—not after every component has already arrived.

Why Panoramic PC Case Cooling Behaves Differently

A conventional tower usually takes air through the front and releases it through the rear and roof. A panoramic or “fish tank” PC case often replaces that front intake with glass, moving intake fans to the side and bottom.

A well-designed panoramic case normally depends on:

This layout can work exceptionally well. But it is less forgiving when the fan directions are wrong.

 reaches the same practical conclusion: glass is not automatically the problem; restricted intake geometry is. Large side and bottom openings can compensate for a glass front, while narrow decorative vents cannot.

The side radiator occupies one of the case’s strongest intake zones. That is good for CPU cooling. It can be bad for everything behind the radiator.

The top radiator occupies the natural exhaust route. That is good for system balance. It forces the radiator to use air that has already been warmed by the GPU, motherboard, memory, and storage.

Top Mount vs Side Mount Radiator: The Real Comparison

The comparison only makes sense when fan direction is included. “Top versus side” is incomplete. A top intake radiator and a top exhaust radiator behave very differently, as do side intake and side exhaust arrangements.

A top-mounted radiator normally gives the cleanest overall PC case airflow configuration.

Cool air enters through the side and bottom. The graphics card receives relatively fresh air. Heat from the CPU loop leaves through the roof instead of entering the main chamber. The rear exhaust fan clears heat around the VRM and socket.

This configuration may produce a higher CPU temperature than a side intake radiator because the radiator is using warmed internal air. That does not automatically mean the system is worse.

A CPU moving from 72°C to 76°C under a sustained workload may have no meaningful effect on performance. A GPU moving from 72°C to 80°C may raise fan speed, hotspot temperature, memory temperature, and noise throughout every gaming session.

For a more detailed explanation of that trade, AceGeek’s guide to 

 explains why the largest visible temperature improvement is not always the most useful improvement.

A side-mounted AIO configured as intake feeds room-temperature air directly through the radiator.

That normally benefits the CPU and coolant loop. It is a sensible choice for Blender rendering, video encoding, code compilation, simulation, or any workload in which CPU package power remains high while the graphics card is lightly loaded.

Every watt removed from the CPU loop enters the case through the radiator exhaust. The GPU then receives air that has already crossed a warm heat exchanger unless bottom intake fans provide a separate source of cooler air.

pros and cons of side-mounting an AIO radiator

 is worth checking before committing to this layout, particularly when the tubing must pass around a long graphics card.

Side exhaust is less common, but I would not dismiss it.

With three strong bottom intake fans feeding the graphics card and a clear top exhaust path, side exhaust can remove CPU radiator heat without dumping it into the visible chamber. The penalty is that the radiator uses warmer internal air, much like a top exhaust radiator.

The risk is pressure imbalance. Three bottom intake fans may not deliver as much real airflow as three side radiator fans and three top exhaust fans, especially after the bottom filter, carpet clearance, radiator resistance, and fan curves are considered.

Most marketing diagrams show arrows. Good testing shows consequences.

In Gamers Nexus testing of the Cooler Master H500P, one front-radiator configuration produced approximately 

. Moving the 240 mm radiator to the top as exhaust resulted in about 

. Gamers Nexus described the top configuration as the better-balanced result. That is exactly why I distrust radiator recommendations based only on CPU package temperature.

Puget Systems found a similar trade during dual-radiator testing in the Fractal Design Define XL R2. Running both radiators as intake produced a 

 result. Changing to a front intake radiator and top exhaust radiator raised the CPU to 

. I would make that exchange in nearly every gaming or GPU-rendering workstation. 

Puget Systems published the complete Define XL R2 test here

These tests did not use every modern panoramic chassis, fan, radiator, or graphics card. They should not be treated as universal temperature promises.

But the pattern is solid: an intake radiator often favors the cooled component, while an exhaust radiator often produces a more balanced internal environment.

Gaming systems are usually dominated by sustained GPU heat. Even when the processor briefly draws high power, the graphics card may release hundreds of watts into the case for hours.

This creates a direct lower intake route for the GPU and a clear upper exhaust route for the CPU radiator.

For CPU Rendering, Compilation, or Simulation

 when CPU temperature, sustained clock speed, or noise under full CPU load is the priority.

A Ryzen 9 or Core Ultra 9 workstation can benefit from feeding the radiator with room air rather than GPU-heated case air. The difference becomes more relevant during 30-minute or multi-hour workloads than during short benchmark bursts.

Keep bottom intake active. Otherwise, the GPU and motherboard will breathe radiator exhaust whenever they are used simultaneously.

 unless the graphics card has an isolated intake route.

Mixed workloads punish weak layouts because both major heat sources are active together. A side radiator intake may cool the CPU but increase GPU fan speed. A top exhaust radiator may slightly raise CPU temperature but reduce the temperature of everything else.

 becomes useful, even for a single-radiator build, because it explains how one heat exchanger can preheat the air used by another component.

Choose side mounting when the motherboard heatsink, EPS cable, memory modules, rear fan, or radiator fittings collide with the top assembly.

Do the full thickness calculation before buying.

A nominal 27 mm radiator combined with 25 mm fans already needs about 

 of vertical space, before screw heads, vibration pads, fittings, cable bends, and manufacturing tolerances are considered. A thicker 38 mm radiator with 25 mm fans needs about 

“Supports a 360 mm radiator” does not guarantee that every 360 mm AIO will fit above every motherboard.

Pump Position and Tube Orientation Still Matter

Radiator location is not only an airflow question. It is also an AIO reliability question.

Closed-loop coolers contain a small amount of air. The highest part of the loop should keep that air away from the pump whenever possible.

Noctua states that top, front, and side radiator mounting can all work, but warns against bottom mounting because air may become trapped in the pump when the radiator is not above it. 

Corsair similarly recommends keeping the radiator above the pump and, for vertical mounting, using tubes at the bottom where the case and tube length allow it. 

Corsair’s official AIO orientation guide

 describes tubes-down with the radiator above the pump as the preferred orientation.

For a top-mounted radiator, the radiator is normally already above the pump. Tube position at the left or right end is usually determined by case clearance, pump fitting orientation, and cable routing.

How I Would Test Top vs Side Radiator Placement

Do not compare layouts using idle temperature. Idle readings are dominated by fan-stop behavior, background processes, ambient variation, pump speed, and motherboard control logic.

Use one CPU-heavy workload, one GPU-heavy workload, and one mixed workload.

Run each test long enough for coolant temperature to stabilize. A two-minute result can hide what happens after the liquid loop and case interior are fully heat-soaked.

Move the radiator or reverse its airflow direction without changing the fan curve, pump mode, power limits, room conditions, or side-panel position.

Top vs Side Radiator in a Panoramic PC Case

For most gaming builds, I would mount the AIO radiator at the top as exhaust and use the side and bottom fans as intake.

That is the practical answer.

A side-mounted radiator configured as intake can deliver cooler air to the radiator and reduce CPU or coolant temperature, but it also pushes radiator-heated air into the main chamber. In a high-power gaming PC, that trade can raise GPU, memory, VRM, and SSD temperatures.

Looks can mislead.

In a panoramic chassis, the side fan wall, bottom intake, top exhaust, GPU cooler, radiator resistance, dust filters, cable chamber, and pump position all interact, so a layout that wins a five-minute CPU test can lose badly during a 45-minute mixed gaming load.

Which result actually matters?

The Best AIO Radiator Placement Depends on What You Are Cooling

The hard truth is that there is no universally “best” AIO radiator placement. There is only the best placement for a specific case, component combination, workload, room temperature, noise target, and fan configuration.

Modern hardware makes that distinction expensive to ignore. NVIDIA lists the GeForce RTX 5090 at 575 W Total Graphics Power, while Intel lists the Core Ultra 9 285K at 250 W Maximum Turbo Power. That is a potential 825 W CPU-and-GPU heat load before the motherboard, pump, memory, storage, and power-conversion losses are counted. NVIDIA’s official RTX 5090 specifications and Intel’s Core Ultra 9 285K specifications make the scale of the problem clear.

A 360 mm radiator does not eliminate that heat. It moves CPU heat from the cold plate to the coolant, from the coolant to the radiator, and from the radiator into whichever air stream passes through it.

Where that warmed air goes is the entire argument.

My default recommendations are straightforward:





Gaming-first system: top-mounted radiator as exhaust



CPU rendering or compiling system: side-mounted radiator as intake



Panoramic case with strong bottom intake: either layout may work well



Restricted top panel: side mounting may outperform top mounting



Dual-radiator system: side intake plus top exhaust is usually the cleanest starting point

Before selecting the case itself, read AceGeek’s guide to building in a panoramic PC case. The radiator decision should be made alongside GPU clearance, bottom ventilation, fan thickness, tube routing, and cable access—not after every component has already arrived.

Why Panoramic PC Case Cooling Behaves Differently

A conventional tower usually takes air through the front and releases it through the rear and roof. A panoramic or “fish tank” PC case often replaces that front intake with glass, moving intake fans to the side and bottom.

That changes the route.

A well-designed panoramic case normally depends on:





Side intake feeding the CPU zone



Bottom intake feeding the GPU



Rear exhaust removing socket-area heat



Top exhaust removing rising mixed air



A separate rear chamber housing the PSU and cables

This layout can work exceptionally well. But it is less forgiving when the fan directions are wrong.

AceGeek’s analysis of tempered glass PC case airflow reaches the same practical conclusion: glass is not automatically the problem; restricted intake geometry is. Large side and bottom openings can compensate for a glass front, while narrow decorative vents cannot.

The side radiator occupies one of the case’s strongest intake zones. That is good for CPU cooling. It can be bad for everything behind the radiator.

The top radiator occupies the natural exhaust route. That is good for system balance. It forces the radiator to use air that has already been warmed by the GPU, motherboard, memory, and storage.

There is no free air.

Top Mount vs Side Mount Radiator: The Real Comparison

The comparison only makes sense when fan direction is included. “Top versus side” is incomplete. A top intake radiator and a top exhaust radiator behave very differently, as do side intake and side exhaust arrangements.

Top-Mounted AIO Radiator as Exhaust

A top-mounted radiator normally gives the cleanest overall PC case airflow configuration.

Cool air enters through the side and bottom. The graphics card receives relatively fresh air. Heat from the CPU loop leaves through the roof instead of entering the main chamber. The rear exhaust fan clears heat around the VRM and socket.

This configuration may produce a higher CPU temperature than a side intake radiator because the radiator is using warmed internal air. That does not automatically mean the system is worse.

A CPU moving from 72°C to 76°C under a sustained workload may have no meaningful effect on performance. A GPU moving from 72°C to 80°C may raise fan speed, hotspot temperature, memory temperature, and noise throughout every gaming session.

I will take the balanced system.

For a more detailed explanation of that trade, AceGeek’s guide to balancing CPU cooling and GPU airflow explains why the largest visible temperature improvement is not always the most useful improvement.

Side-Mounted AIO Radiator as Intake

A side-mounted AIO configured as intake feeds room-temperature air directly through the radiator.

That normally benefits the CPU and coolant loop. It is a sensible choice for Blender rendering, video encoding, code compilation, simulation, or any workload in which CPU package power remains high while the graphics card is lightly loaded.

But there is a bill.

Every watt removed from the CPU loop enters the case through the radiator exhaust. The GPU then receives air that has already crossed a warm heat exchanger unless bottom intake fans provide a separate source of cooler air.

Side intake works best when:





The case has three unobstructed bottom intake fans



The GPU sits high enough above the bottom fans to breathe



The top panel has strong exhaust capacity



The rear exhaust is not blocked by tubing



The radiator filter and side vent are not excessively restrictive



The graphics card is not pressed close to the glass panel

AceGeek’s full analysis of the pros and cons of side-mounting an AIO radiator is worth checking before committing to this layout, particularly when the tubing must pass around a long graphics card.

Side-Mounted AIO Radiator as Exhaust

Side exhaust is less common, but I would not dismiss it.

With three strong bottom intake fans feeding the graphics card and a clear top exhaust path, side exhaust can remove CPU radiator heat without dumping it into the visible chamber. The penalty is that the radiator uses warmer internal air, much like a top exhaust radiator.

The risk is pressure imbalance. Three bottom intake fans may not deliver as much real airflow as three side radiator fans and three top exhaust fans, especially after the bottom filter, carpet clearance, radiator resistance, and fan curves are considered.

Count resistance, not frames.



What Real Thermal Testing Shows

Most marketing diagrams show arrows. Good testing shows consequences.

In Gamers Nexus testing of the Cooler Master H500P, one front-radiator configuration produced approximately 47°C CPU delta over ambient and 59°C GPU delta over ambient. Moving the 240 mm radiator to the top as exhaust resulted in about 51.8°C CPU delta and 50.5°C GPU delta.

The CPU became roughly 4.8°C warmer, but the GPU improved by about 8.5°C. Gamers Nexus described the top configuration as the better-balanced result. That is exactly why I distrust radiator recommendations based only on CPU package temperature.

Puget Systems found a similar trade during dual-radiator testing in the Fractal Design Define XL R2. Running both radiators as intake produced a 66°C CPU and 85°C GPU result. Changing to a front intake radiator and top exhaust radiator raised the CPU to 69°C, but reduced the GPU to 78°C.

That is a 3°C CPU loss for a 7°C GPU gain. I would make that exchange in nearly every gaming or GPU-rendering workstation. Puget Systems published the complete Define XL R2 test here.

These tests did not use every modern panoramic chassis, fan, radiator, or graphics card. They should not be treated as universal temperature promises.

But the pattern is solid: an intake radiator often favors the cooled component, while an exhaust radiator often produces a more balanced internal environment.

Choose the Radiator Position by Workload

For a Gaming PC

Use a top-mounted AIO as exhaust first.

Gaming systems are usually dominated by sustained GPU heat. Even when the processor briefly draws high power, the graphics card may release hundreds of watts into the case for hours.

My preferred panoramic gaming layout is:





Three side fans as intake



Three bottom fans as intake



Top radiator fans as exhaust



One rear fan as exhaust



Intake curves linked partly to GPU temperature



Radiator fans linked to coolant or CPU temperature

This creates a direct lower intake route for the GPU and a clear upper exhaust route for the CPU radiator.

For CPU Rendering, Compilation, or Simulation

Use a side-mounted radiator as intake when CPU temperature, sustained clock speed, or noise under full CPU load is the priority.

A Ryzen 9 or Core Ultra 9 workstation can benefit from feeding the radiator with room air rather than GPU-heated case air. The difference becomes more relevant during 30-minute or multi-hour workloads than during short benchmark bursts.

Keep bottom intake active. Otherwise, the GPU and motherboard will breathe radiator exhaust whenever they are used simultaneously.

For Mixed CPU and GPU Rendering

Start with top exhaust unless the graphics card has an isolated intake route.

Mixed workloads punish weak layouts because both major heat sources are active together. A side radiator intake may cool the CPU but increase GPU fan speed. A top exhaust radiator may slightly raise CPU temperature but reduce the temperature of everything else.

This is where AceGeek’s guide to dual-radiator PC airflow becomes useful, even for a single-radiator build, because it explains how one heat exchanger can preheat the air used by another component.

When Top Clearance Is Tight

Choose side mounting when the motherboard heatsink, EPS cable, memory modules, rear fan, or radiator fittings collide with the top assembly.

Do the full thickness calculation before buying.

A nominal 27 mm radiator combined with 25 mm fans already needs about 52 mm of vertical space, before screw heads, vibration pads, fittings, cable bends, and manufacturing tolerances are considered. A thicker 38 mm radiator with 25 mm fans needs about 63 mm.

“Supports a 360 mm radiator” does not guarantee that every 360 mm AIO will fit above every motherboard.

Measure twice.

Pump Position and Tube Orientation Still Matter

Radiator location is not only an airflow question. It is also an AIO reliability question.

Closed-loop coolers contain a small amount of air. The highest part of the loop should keep that air away from the pump whenever possible.

Noctua states that top, front, and side radiator mounting can all work, but warns against bottom mounting because air may become trapped in the pump when the radiator is not above it. Noctua’s AIO placement guide explains the reasoning directly.

Corsair similarly recommends keeping the radiator above the pump and, for vertical mounting, using tubes at the bottom where the case and tube length allow it. Corsair’s official AIO orientation guide describes tubes-down with the radiator above the pump as the preferred orientation.

For a side-mounted radiator:





Keep the top of the radiator above the pump



Prefer tubes at the bottom when routing permits



Avoid sharp bends against the GPU



Keep tubes away from fan blades



Do not force the fittings sideways



Confirm the side panel closes without compressing the tubes

For a top-mounted radiator, the radiator is normally already above the pump. Tube position at the left or right end is usually determined by case clearance, pump fitting orientation, and cable routing.

How I Would Test Top vs Side Radiator Placement

Do not compare layouts using idle temperature. Idle readings are dominated by fan-stop behavior, background processes, ambient variation, pump speed, and motherboard control logic.

Use a repeatable test.

Record a Baseline

Record:





Room temperature



CPU package temperature



GPU core and hotspot temperature



Coolant temperature, when available



VRM temperature



SSD temperature



CPU and GPU clock speed



Pump and fan RPM



System noise from the same position

Run Three Workloads

Use one CPU-heavy workload, one GPU-heavy workload, and one mixed workload.

Examples include:





Cinebench or Blender CPU rendering



A repeatable game benchmark or GPU stress test



Simultaneous CPU and GPU load

Run each test long enough for coolant temperature to stabilize. A two-minute result can hide what happens after the liquid loop and case interior are fully heat-soaked.

Change One Variable

Move the radiator or reverse its airflow direction without changing the fan curve, pump mode, power limits, room conditions, or side-panel position.

Then compare the complete system.

A side intake layout that lowers CPU temperature by 4°C but raises GPU hotspot by 9°C is not a clean win. A top exhaust layout that raises CPU temperature by 3°C while reducing GPU fan noise may be the better everyday configuration.

Mistakes That Ruin Both Layouts

Using Top Intake Because “Cold Air Is Better”

Cold air is better for the radiator, but top intake can send warmed air downward and fight the rear or side exhaust path.

Fans are stronger than natural convection, so “heat rises” is not a complete engineering explanation. Still, top exhaust usually aligns better with the shortest practical route for removing heat from a tower-shaped case.

Filling Every Fan Mount

More fans can add noise, turbulence, recirculation, and competing pressure zones.

A top-front exhaust fan can steal side-intake air before it reaches the CPU or GPU. A top-front intake fan can push air back toward the side intake. The correct fan count is the number required to create one controlled route.

Ignoring Filters

A radiator and dust filter in series create far more resistance than an open exhaust grille.

Three filtered intake fans may move less actual air than two unrestricted exhaust fans. That is why pressure cannot be calculated by counting fans or adding the free-air CFM numbers printed on product pages.

Testing With the Glass Removed

Removing the glass changes the system.

It may improve access to room air, eliminate pressure behavior, and conceal recirculation that occurs with the case closed. Test the PC in the configuration you will actually use.

FAQs

Is a top or side radiator better in a panoramic PC case?

A top-mounted radiator is generally better for gaming and mixed workloads because it exhausts CPU heat directly from the case, while a side-mounted intake radiator generally delivers cooler air to the AIO and favors CPU temperature. The better choice depends on GPU heat, bottom intake capacity, top ventilation, and workload.

For a gaming build, begin with top exhaust. For sustained CPU rendering, side intake may produce lower coolant and CPU temperatures. Test both when the chassis supports easy relocation.

Should a side-mounted AIO radiator be intake or exhaust?

A side-mounted AIO radiator should usually be configured as intake when maximum CPU cooling is the priority, or as exhaust when preventing radiator heat from entering the case is more important. Intake uses cooler room air, while exhaust uses warmer case air but better protects the GPU, memory, VRM, and storage.

In most panoramic cases, side intake works well when bottom fans independently supply fresh air to the graphics card and top fans provide a strong exhaust route.

Is top-mounted AIO exhaust bad for CPU temperature?

A top-mounted AIO exhaust is not bad for CPU temperature; it simply uses air that has already passed through the case, so CPU or coolant temperature may be slightly higher than with a side intake radiator. The benefit is that radiator heat leaves the chassis instead of being released around the graphics card and motherboard.

A modest CPU increase can be worthwhile when it produces lower GPU temperature, reduced fan noise, and better internal component cooling.

Should I mount my AIO radiator tubes up or down?

A vertically mounted AIO radiator should preferably have its tubes at the bottom while the top of the radiator remains above the pump, allowing trapped air to collect away from the pump inlet. Tubes-up can still operate when required, but it may produce more noise if air collects near the fittings.

Top-mounted radiators normally place the radiator above the pump automatically, so left-versus-right tube routing is mainly a clearance and cable-management decision.

Can I install an AIO radiator at the bottom of a panoramic case?

A bottom-mounted CPU AIO radiator is generally not recommended because the pump can become the highest point in the loop, allowing air to collect inside the pump and potentially causing noise, reduced cooling performance, or shorter service life. Bottom mounts are better reserved for intake fans or properly designed custom-loop radiators.

Use the top or side position for the CPU AIO and preserve the bottom mounts for direct GPU intake whenever possible.

What is the best PC case airflow configuration for a panoramic case?

The best panoramic PC case airflow configuration usually uses side and bottom fans as intake, top and rear fans as exhaust, and a slightly positive pressure balance after filters and radiator resistance are considered. This arrangement supplies fresh air to the GPU, supports the CPU cooler, and gives heated air a short exit route.

With a top-mounted AIO, use it as exhaust. With a side-mounted intake AIO, keep strong bottom intake and enough top exhaust to prevent radiator heat from accumulating.

Build Around the Heat, Not the Glass

My verdict is blunt: top exhaust is the safer default for a gaming-focused panoramic PC case, while side intake is the more aggressive CPU-cooling option.

Do not choose between them because one position looks cleaner in a product photo.

Check the CPU power. Check the GPU power. Measure radiator and fan thickness. Confirm tube reach. Protect the pump position. Map the intake and exhaust route. Then test CPU, GPU hotspot, coolant, fan RPM, and noise under the workload you actually run.

Before ordering your chassis, compare radiator support, GPU clearance, side ventilation, bottom intake area, and cable space across AceGeek’s panoramic and high-airflow PC case options.
