Compact 40 mm case fan

The NDLIULEI KF0420S1H-R is a 40x40x20 mm case fan designed for tight chassis spaces. It runs on 12 V power and draws 1.6 W, making it suitable for small-form-factor builds or targeted component cooling. Buyers needing higher airflow for larger enclosures should look elsewhere.

12 V 1.6 W power specification

The single specification that decides fit is the 12 V, 1.6 W electrical rating. This determines whether the fan matches the header or controller available in the system. No other voltage or power option is offered for this model.

Sustained low-power operation

At a constant 1.6 W draw the motor maintains steady rotation without the current spikes seen in higher-wattage fans. This behaviour keeps thermal output predictable during extended use in confined layouts.

Questions about this item

How loud is the 1.6 W fan in a live system?

At 1.6 W the motor draws little current, so the 40 mm blade typically runs quiet enough for desk-side builds.

What connector does the 12 V unit use and what does it limit?

The two-wire 12 V lead plugs into a standard motherboard header and fixes speed at full voltage.

Will the 40×40×20 mm frame fit my tight bracket?

The 40 mm square by 20 mm thick body matches the 4020 form factor and clears most compact chassis slots.
