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.Technical Data
