Compact 40 mm cooling module

This 40 x 40 x 10 mm fan runs on 12 V DC and draws 0.05 A through a two-pin connector. The sleeve bearing keeps operation simple for tight enclosures. It ships in a 100-piece pack for volume builds. The black frame carries no lighting.

Two-pin DC power interface

The two-wire lead replaces fans that use three- or four-pin headers and removes PWM control. Upgrade when the host board only supplies constant 12 V and speed regulation is not required. The change is worth it for legacy DVR, humidifier or satellite chassis that lack fan-speed headers.

4500 RPM airflow ceiling

At 4500 RPM the fan moves enough air for small CPU coolers and auxiliary spots in compact cases. Headroom ends when static pressure must overcome dense heatsink fins or long duct runs. Buyers who need variable speed or higher static pressure should look elsewhere.

Questions about this item

Will the 40×40×10 mm frame and two mounting holes fit my CPU cooler's fan bracket?

The fan measures 40 mm by 40 mm by 10 mm thick with the standard square mounting pattern used on 4010 coolers, so it matches brackets designed for that footprint.

How do I connect the 2-pin lead to a 12 V header without reversing polarity?

Align the red wire to the +12 V pin and the black wire to ground; the keyed connector only seats one way, preventing a reversed connection.

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

Sleeve bearings typically show increased noise or reduced speed after extended continuous use; monitor for rattling or rpm drop and swap the unit when either appears.
