Compact 40 mm cooling for tight builds

This 40 mm by 20 mm dual ball bearing fan runs on 12 V at .08 A and fits small enclosures such as routers, mini PCs or single-board computers. The two-pin connector provides simple power without PWM control. It is suited to builders who need a low-profile airflow solution where larger fans cannot mount.

Airflow headroom for low-heat components

The fan moves enough air for modest thermal loads like a router CPU or a small embedded board. Under sustained high-wattage loads the 4020 frame reaches its limit quickly, so it is not intended for desktop CPUs, GPUs or any component that generates significant heat. Buyers who need higher static pressure or greater CFM should look at larger frame sizes.

Direct replacement for 4020 two-pin fans

It matches the 40 mm by 20 mm footprint and 12 V .08 A rating of many stock router and appliance fans, making the swap straightforward. The dual ball bearing design lasts longer than sleeve equivalents in continuous operation. The upgrade is worthwhile when the original fan has failed or become noisy, but it does not add speed control or higher airflow beyond the original specification.

Questions about this item

Will the 40 mm 12 V .08 A fan fit the same mounting holes as my existing 40 mm cooler?

Yes — the frame is 40 mm square with 20 mm thickness, matching the standard 4020 footprint used on most router and small-form-factor CPU coolers.

How can I confirm the dual ball bearing is spinning correctly after install?

Power the 2-pin connector from a 12 V source; the rotor should start instantly, run without rattling, and draw roughly 0.08 A at full speed.

Does the package include screws or a Molex adapter, or must I supply them?

Only the fan unit is supplied; mounting screws and any 2-pin to Molex or motherboard adapter must be purchased separately.
