Slim 92 mm fan for tight builds

The Silverstone Air Slimmer AS90B is a 92 mm case fan only 15.2 mm thick, designed for compact chassis or heatsink clearance where standard 25 mm fans will not fit. Its hydraulic bearing and eleven blades target both airflow and static pressure for restricted spaces.

PWM range limits low-end airflow

Speed is controlled via a 4-pin PWM connector across a 500 to 2,500 RPM range, delivering 5.38 to 45.73 CFM with noise from 11.3 to 32 dBA. At the minimum RPM the airflow may be insufficient for components that need constant pressure, so the curve must be tuned for the thermal load.

Rubber pads and non-LED black frame

Integrated rubber padding on the mounting corners dampens vibration transmitted to the case or heatsink. The all-black, non-LED frame keeps the appearance neutral for windowed or stealth builds, while the slim profile eases cable routing in dense layouts.

Questions about this item

Should I pick the 92 mm slim version or a standard 25 mm fan?

The AS90B is 15.2 mm thick, so it fits tight heatsink clearances where a 25 mm fan cannot.

What does the 45.73 CFM peak mean for my CPU temps?

At 2500 RPM the fan moves 45.73 CFM, giving strong airflow through dense fins while staying at 32 dBA.

Does the 4-pin PWM header let the motherboard control the full 500 to 2500 RPM range?

Yes, the 4-pin connector enables PWM control across the entire 500~2500 RPM span.
