Compact 4 cm case fan for tight builds

This 40 mm square fan fits small-form-factor cases and server chassis where space is limited. The hydraulic bearing reduces friction for quieter operation than sleeve alternatives. A three-pin connector provides simple voltage control on most motherboards. It suits builders who need basic airflow in confined layouts.

Low power draw and quiet running

At 12 V the unit consumes 0.72 W, adding minimal load to the power supply. Hydraulic bearing construction keeps acoustic output low during normal use. The 10 mm thickness allows installation in shallow mounts without blocking adjacent components. Buyers needing PWM speed curves or higher static pressure should consider other models.

Questions about this item

How do I install the 40 mm hydraulic-bearing fan and which step is often missed?

Mount the 40×40×10 mm frame with four screws, connect the three-pin plug to a 12 V header, and check the wire order — reversing the sense lead is the step most people miss.

What maintenance will the YY4010H12S need later?

The hydraulic bearing is sealed; just blow dust off the blades every few months — no lubrication or bearing replacement is required.
