120 mm 30 mm PWM Case Fan
The Cooler Master MasterFan A120 is a 120 mm case fan with a 30 mm frame and a 4-pin PWM connector. Aluminum blades and a three-phase motor reduce vibration while maintaining consistent airflow. A 0.6 mm tip clearance helps limit leakage through restrictive paths. It suits builders who need focused pressure in tight cooling layouts.
Upgrade from standard 25 mm fans
Basic 25 mm fans often lose pressure when pushing air through dense radiators or restrictive heatsinks. The thicker frame and higher static pressure of this model keep airflow moving where thinner fans stall. The jump is worth it when cooling density rises and standard fans cannot sustain delivery. Buyers who only need case airflow without restriction will not benefit from the added depth.
76.9 CFM airflow at 6.1 mmH2O pressure
At maximum speed the fan delivers 76.9 CFM with 6.1 mmH2O of static pressure while peaking at 29.7 dBA. That headroom handles dense radiator stacks and restricted heatsinks without choking. In open mesh cases with no obstruction the extra pressure goes unused, so the fan runs louder than necessary for simple exhaust duty.

Otázky k tomuto produktu
Will the 30mm thick frame fit my 120mm mounting holes?
Yes, the fan uses standard 120mm hole spacing; the 30mm depth only adds thickness toward the interior, so check clearance behind the mount.
How do I connect the 4-pin PWM cable so the motherboard controls the 0-2500 RPM range?
Plug the 4-pin connector into a motherboard PWM header and enable PWM mode in BIOS; the fourth wire carries the speed signal for automatic control.
When should I expect the two-ball bearing to need replacement?
Two-ball bearings typically last several years of continuous use; listen for new grinding or rattling noises that indicate wear.
