Compact 40 mm 12 V case fan

This 40 x 40 x 10 mm fan runs on 12 V and draws 0.5 W through a two-wire connection. It is built for tight spaces where a small form-factor cooler is required. The kde1204pfs3-8 model fits standard 4010 mounting holes in compact enclosures.

Suits small chassis and replacement builds

Buyers needing higher airflow or PWM speed control should look elsewhere. The two-wire design does not support variable-speed headers. Systems that demand larger frame sizes or greater static pressure will not be served by this unit.

Questions about this item

Does this 12 V .5 W fan plug into a standard 3-pin or 4-pin motherboard header?

The fan has a 2-wire lead so it connects to a 2-pin 12 V header; a 3-pin or 4-pin header will work but speed reporting and PWM control are not available.

Will the 40 mm frame fit the same mounting holes as my existing 4010 fan?

Yes, the 40 x 40 x 10 mm dimensions match the 4010 form factor so existing screw holes line up.
