Compact 80 mm Server Fan

The OEM Industries CHC8012BB-N-AH is an 80 mm square fan with a 38 mm thickness designed for server and workstation chassis. It uses a ball bearing and a 4-pin PWM connector for speed control. The black frame houses a 12 V motor rated at 0.37 A. This unit is a fan only, without heatsink or LED lighting.

Direct 8038 Form-Factor Replacement

It fits the standard 8038 mounting pattern used in many 1U and 2U rack units. The 4-wire interface allows the system to regulate RPM based on thermal load, replacing older 3-pin models that run at fixed speed. The jump is worth it when the chassis BIOS or BMC expects PWM feedback for fan-fault detection.

Steady Airflow Under Constant Load

Ball-bearing construction maintains consistent rotational speed during continuous 24/7 operation in dense enclosures. The 4-pin control loop adjusts duty cycle without the stiction that can stall sleeve bearings after long idle periods. Sustained throughput stays stable because the bearing preload does not relax with temperature cycles.

Questions about this item

Will the 80 mm by 38 mm frame fit my server chassis fan slot?

The cooler measures 80 mm square and 38 mm thick, so it fits any standard 8038 mounting cut-out.

How do I connect the 4-pin PWM lead correctly?

Plug the 4-pin connector into a 12 V PWM header; the fourth wire carries the speed signal that the board expects.

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

Ball bearings typically run for years; replace the unit if noise rises or RPM drops below the rated 0.37 A draw.
