Fan Silverstone Air Slimmer 90 9.2 cm Black 500-2500 RPM Hydraulic

The SilverStone Air Slimmer 90 is a 92 mm slim-profile cooling fan designed for small form factor (SFF) systems. With a total thickness of 15.2 mm and a speed range of 500–2,500 RPM controllable via PWM, it combines compact dimensions with a wide performance window. The fan uses a hydraulic bearing for reduced noise and reliable operation, and its 11 high-efficiency blades deliver substantial airflow and pressure for heatsink and exhaust applications.

Advantages

Its ultra-slim 15.2 mm design enables installation in space-constrained enclosures while maintaining strong airflow. The 11-blade rotor is optimized for high airflow volume and good static pressure (0.11–2.29 mmH2O), suitable for pushing air through heatsinks and tight channels. PWM control allows tailored performance across a broad 500–2,500 RPM range, and the hydraulic bearing improves operational quietness and longevity.

Suitable for

• Small form factor (SFF) desktop PCs
• CPU heatsinks and compact GPU or chipset cooling
• Case exhaust or intake in tight enclosures
• Systems requiring PWM speed control and low-noise operation

How to use

Install the fan in the desired position with the airflow direction pointing toward the component or exhaust Path you intend to cool. Use the four mounting holes and appropriate screws compatible with 92 mm fan mounts and secure the fan to avoid vibration. Connect the fan's PWM cable to a motherboard or fan controller header that supports PWM (4-pin) to enable speed regulation between 500 and 2,500 RPM. Ensure airflow orientation and cable routing do not obstruct other components.

Recommendations

For optimal performance in SFF systems, position the Air Slimmer 90 where restricted clearance would prevent standard fans, and configure PWM profiles to balance noise and cooling: lower RPM for idle or low-load periods and higher RPM under sustained load. Periodic cleaning of dust from blades and heatsink channels will help maintain airflow and static pressure.
