The CORSAIR AF120 SLIM 120mm PWM Fluid Dynamic Bearing Fan is just 15mm thin, delivering powerful airflow in compact builds where space is at a premium. PWM-controlled speeds from 600 RPM up to 2,000 RPM means powerful cooling and near-silent operation, all in an amazingly low-profile design. The AF120 SLIM spins as quietly as 27.5 dBa, while its fluid dynamic bearing ensures exceptional durability and cooling performance, pushing up to 56.3 CFM of air with 1.9mm-H2O of static pressure at full speed. Support for zero RPM PWM signals enables the fan to stop completely to eliminate noise entirely. With its ultra-thin 120x15mm form-factor, the AF120 SLIM gives nearly any PC uncompromised compact cooling.
