40 mm Mgalev fan for compact cooling

The OEM Industries KD1204PKVX is a 40 mm square fan built with Mgalev bearing technology. It runs on 12 V and draws 1.6 W through a standard three-wire connection. The unit is sold new and contains no LED lighting. It suits builders who need a low-profile airflow component for tight spaces.

Straightforward three-wire mounting

Installation consists of aligning the 40 mm square frame with the matching cut-out and securing it with four screws. The three-wire lead plugs directly into a 12 V fan header; no adapter or PWM configuration is required. The only common issue is forgetting to route the short cable clear of adjacent heatsink fins before tightening the last screw.

Targeted airflow for small heatsinks

At 1.6 W the fan delivers enough static pressure for 40 mm tower coolers or chipset heatsinks in industrial and embedded systems. It cannot sustain the airflow demanded by larger desktop CPU coolers or multi-GPU enclosures. Buyers needing higher CFM for overclocked processors should look at larger frame sizes.
