Compact 40mm CPU fan for tight builds

This 40mm axial fan from OEM Industries is built for small-form-factor systems and replacement cooling in space-constrained chassis. It targets builders who need a direct-fit cooler for legacy boards or industrial enclosures where larger heatsinks cannot be mounted.

Dual ball bearing rated 18000 RPM

The unit spins at 18000 RPM with a 10 percent tolerance and draws 0.90A at 12V through a three-wire connector. That speed and airflow profile is the deciding factor — systems requiring lower noise or lower static pressure should look elsewhere.

Simple three-wire mount with high noise output

Four mounting holes on a 40mm square pattern align with standard 40mm fan brackets. The 72.00dB(A) rating means audible whine is normal; verify your header supplies 12V at 0.90A and that the chassis can vent the exhaust path.

Questions about this item

What does 18000 RPM mean for actual cooling inside a case?

The fan spins at 18000 RPM with a 10 percent tolerance, moving a high volume of air through a 40 mm frame to pull heat off a small heatsink quickly.

What does the 3-wire power connector control and report?

The three-wire connector supplies 12 V at 0.90 A, carries a tachometer signal so the motherboard can monitor speed, but has no PWM wire for automatic speed control.

Will the 40 mm by 28 mm frame fit my motherboard mounting holes?

The cooler measures 40 mm square and 28 mm thick, so it only fits boards with 40 mm mounting centres or a compatible retention bracket.
