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 & near-silent operation, all in an amazingly low-profile design. The AF120 SLIM spins as quietly as 27.5 d Ba, while its fluid dynamic bearing ensures exceptional durability & 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 120x 15mm form-factor, the AF120 SLIM gives nearly any PC uncompromised compact cooling. Features Thin Profile for Small-Form-Factor Cases: The AF120 SLIM’s 15mm profile fits in nearly any PC build, especially small-form-factor cases, giving you the powerful airflow you need while taking up minimal space. Push Air Without Pushing the Decibels: A low-noise 120mm fan blade spins as quietly as 27.5 d Ba. Keep Your System Cool: Powerful PWM-controlled fan speeds from 600 RPM up to 2000 RPM, pushing up to 56.3 CFM of air with 1.9mm-H2O of static pressure. Fluid Dynamic Bearing: Lubricant between the shaft & bearing greatly reduces friction, ensuring exceptional durability & minimal noise. Zero RPM Mode Support: Stops the fan entirely when sent a zero RPM PWM signal, completely eliminating fan noise. Universal 120x 15mm Sizing: Fits in Mini-ITX case fan mounts, radiators, & heatsinks.
