Compact 40×20 mm Cooling Fan

This OEM Industries square fan measures 40 by 20 millimetres and operates at 12 volts with a 2.4 watt draw. The three-wire connector provides tachometer feedback for speed monitoring. It is intended for builders who need a low-profile cooler in tight chassis spaces.

Mgalev Bearing Limits

The Mgalev bearing reduces friction and extends service life compared with traditional sleeve designs. It still relies on a single fan stage, so airflow scales linearly with voltage and cannot match dual-fan or larger-frame coolers. Acoustic output rises noticeably when the unit runs at full voltage.

2.4 W Thermal Headroom

At 2.4 watts the fan suits low-power CPUs, embedded boards or auxiliary component cooling. It cannot dissipate the heat loads of modern mainstream desktop processors under sustained load. Systems requiring higher thermal capacity will need a larger heatsink or additional airflow.

Soalan tentang produk ini

Which size version of the GM1204PKBX-8A fits a 40 mm by 20 mm mounting pattern?

The 4020 square frame measures 40 mm by 20 mm, so this model matches that exact footprint.

What does the 2.4 W rating tell me about heat dissipation once the fan is installed?

At 12 V the fan draws 2.4 W, indicating the motor power available to move air through the heatsink.

How does the 3-wire connection limit speed control compared with a 4-wire PWM header?

The three wires provide power, ground and a tachometer signal; voltage regulation is the only way to vary speed.
