Silverstone Technology Air Slimmer 120 15.6mm PWM Fan SST-AS120B Black
A 15.6 mm thick 120 mm PWM fan with 9 scimitar blades delivers up to 1800 RPM, 63.7 CFM and 31.7 dBA for space-limited builds
- 6 mm slim profile fits tight builds
- 9 scimitar blades push air through radiators fast
- 0–1800 RPM PWM gives full speed control
- 7 CFM peak airflow clears heat quickly
- All-copper FDB runs quiet at 31.7 dBA and lasts longer
Slim 120 mm fan for tight builds
The Silverstone Air Slimmer 120 measures 15.6 mm thick and fits 120 mm mounts where standard fans cannot. Its nine scimitar blades are shaped to push air through radiators or dense heatsinks in compact cases. Full-range PWM control lets the motor spin from 0 to 1800 RPM. The all-copper fluid dynamic bearing reduces friction for a long service life.
PWM curve and blade geometry
Full-range PWM means the fan can stop completely at low load and ramp smoothly to 1800 RPM when cooling demand rises. The scimitar blade profile raises static pressure to 63.7 CFM while keeping peak noise at 31.7 dBA. A bevelled intake grille smooths airflow entry, improving exhaust efficiency through restrictive fins. No extra software or controllers are bundled.
All-copper bearing and standard mounting
The fluid dynamic bearing uses all-copper construction to minimise wear during continuous operation. Four standard 120 mm screw holes align with common radiator, heatsink and case mounts. The 15.6 mm depth clears narrow side-panel gaps and slim tower coolers. Builders needing thicker fans or higher maximum airflow will need a different model.

Questions about this item
Will the Fluid Dynamic Bearing need lubrication or replacement over time?
The all-copper Fluid Dynamic Bearing is sealed and designed for long lifespan without user maintenance.
At 1800 RPM the fan reaches 31.7 dBA — is that the loudest it gets under continuous load?
Yes, 31.7 dBA is the specified maximum acoustic level at the top speed of 1800 RPM.
Does the 15.6 mm slim frame restrict airflow enough to raise case temperatures during all-day operation?
The 9 scimitar blades and bevelled intake grille deliver up to 63.7 CFM, providing strong airflow despite the slim profile.
