Compact 40 mm Hydro Bearing Fan

This 4010 case fan measures 40 mm square by 10 mm thick and uses a hydro bearing for quiet operation. It is designed for CPU coolers and other tight spaces where a small frame is required. The fan runs on 12 V power and includes both 3-pin and 4-pin connectors.

Fits Restricted Mounts

The slim 10 mm profile allows installation in narrow chassis, laptop coolers or compact heatsinks where larger fans cannot fit. Dual 3-pin and 4-pin headers give flexibility for voltage or PWM control without needing adapters. Builders needing higher airflow or larger frame sizes should look elsewhere.

Questions about this item

How does the 12 V 4010 fan cope with continuous 24-hour operation?

The hydro bearing is built for long running times and keeps friction low, so the fan stays stable during all-day use.

What noise and heat should I expect when the 40 mm fan runs at 12 V all day?

Hydro bearing operation stays quiet, and the low power draw at 12 V means little extra heat inside the case.
