90 mm square cooler for server cases

This 90 mm square cooler fits standard 9038 mounting holes and ships as a fan-only unit in black. It targets system builders who need a direct replacement for a 90 mm server fan without additional heatsink hardware.

Upgrade from a worn 3-pin 90 mm fan

The CHD9212BB-OA(E) replaces an existing 90 mm 3-pin fan that has become noisy or failed. The jump is worth it when the current unit runs on 12 V at 0.58 A and uses a ball bearing for longer service life.

Verify 3-pin header and 9038 spacing

Confirm the motherboard or fan controller provides a 3-pin header supplying 12 V. Measure the mounting holes to match the 9038 pattern and ensure clearance for the 38 mm thickness before ordering.

Questions about this item

Will the 90mm square cooler fit my server case fan mounts?

The fan measures 90 by 38 mm with a square frame, matching standard 90 mm mounting holes used in many server chassis.

How do I connect the 3-pin power connector correctly?

Align the keyed 3-pin plug with the motherboard or fan-controller header so the guide tab seats in the slot; forcing it backwards bends pins.

When should I plan to replace the ball-bearing fan?

Ball bearings typically run for tens of thousands of hours; replace the unit if noise increases or rpm drops below spec.
