Can radiator fans and case fans be used interchangeably? We compare static pressure, airflow, CFM, mmH₂O, radiator resistance, noise, and real 120mm fan specifications to show where each fan actually works best.

Learn where airflow fans and static-pressure fans belong in a PC, how CFM and mmH₂O interact, and which fan type fits radiators, filters, and open vents.

Learn how to tell whether a PC fan is better for radiators or case airflow by reading static pressure, CFM, RPM, noise, PWM control, radiator restriction, and real system heat load.
