Compact 80 mm CPU cooler for tight builds

The OEM Industries 3110RL-04W-B86 is a square DC fan measuring 80 by 25 mm that mounts directly on a processor heatsink. It runs on 12 V at 0.33 A and connects through a standard three-pin header. The ball-bearing design and black finish suit replacement or custom cooling in small-form-factor systems.

Suits repair technicians

This cooler fits situations where the motherboard header and mounting holes match the 80 mm footprint and three-wire interface. Builders who require PWM control, larger airflow, or a four-pin connector should look elsewhere because this unit provides only fixed-speed operation on three pins.

12 V 0.33 A three-pin power draw decides

The cooler draws 0.33 amps at 12 volts through its three-pin connector, so the motherboard header must supply that current without PWM signalling. If the board expects a four-pin PWM fan or a different current profile, this model will not function as intended.

Questions about this item

Will the 3110RL-04W-B86's 3-pin connector work with my motherboard's 4-pin CPU fan header?

Yes, the 3-pin plug fits a 4-pin header; the fan will run at full 12 V speed since PWM control is not present on the third wire.

How can I confirm the ball-bearing fan is spinning correctly once installed?

Check the BIOS hardware monitor or a monitoring utility — it should report a steady RPM reading for the CPU fan header with no error warnings.

Does the cooler include mounting hardware for a specific socket, or only the 80 mm fan unit?

The package contains the 80 mm square fan with 3-pin lead; any retention brackets, back-plates or thermal paste must be sourced separately.
