RK Series Server Fan

RK92

RK 92 BK

A 92 x 92 x 32 mm high-pressure PWM fan designed for 4U server coolers, compact workstations, and small form factor systems that need focused airflow through dense thermal structures.

Compact footprint. Server-class pressure. RK92 is built for tight airflow paths where a standard case fan is not enough.

Pressure Focus

Focused airflow for 4U coolers and compact chassis paths.

The 32 mm frame depth gives RK92 more room for pressure-oriented airflow, while PWM control keeps speed responsive to server or workstation thermal load.

Server Pressure

Built for dense fin stacks and restricted airflow paths.

RK92 is tuned for pressure-oriented cooling, helping air move through 4U cooler fins, compact chassis vents, and tight internal layouts.

32 mm Frame

More depth than a standard 92 mm case fan.

The 92 x 92 x 32 mm body gives the fan a stronger pressure profile while staying compact enough for server and small form factor cooling positions.

PWM Control

Responsive speed scaling up to 4000 RPM.

4-pin PWM control lets RK92 increase airflow under thermal load and settle back when the system has more cooling headroom.

Two Ball Bearing

Designed for long-duration operation.

A two ball bearing structure supports server-style continuous use where stability and repeatable airflow matter more than lighting effects.
