  • Compact 40 × 40 × 10 mm size fits tight chassis

Compact 40 mm 12 V case fan

This 40 mm square fan fits tight chassis spaces where larger units cannot be mounted. It runs on a standard 12 V supply and draws 1.08 W, making it suitable for targeted component cooling or small-form-factor builds. The slim 10 mm profile helps it clear low-profile heatsinks and crowded motherboard layouts.

Low power draw and modest airflow

At 1.08 W the motor adds minimal load to the system power budget and generates little heat of its own. The small frame moves a focused stream of air through restricted vents without the noise penalty of larger fans spinning at high speed. It is not intended for high-static-pressure radiators or builds that demand maximum case throughput.

Questions about this item

How do I install the 40mm FD1240105S-1N fan and which step is commonly missed?

Mount the 40mm frame using four screws through the corner holes, then connect the two-wire 12V lead to a motherboard header or fan controller; the step often missed is checking airflow direction so the fan blows the intended way.

What maintenance will the FD1240105S-1N 12V 1.08W fan need over time?

Expect to clean dust from the 4010 blades and frame every few months with compressed air; if bearing noise appears or airflow drops, replace the entire 40mm unit as it is not serviceable.
