Compact 40 mm cooling fan

The Zyvpee U40X12MLZ7-51 K16 is a 40 mm square case fan designed for tight spaces such as small-form-factor builds or CPU cooler replacements. It suits builders who need a low-profile airflow source where larger fans cannot fit. Buyers requiring higher static pressure or greater airflow volume should look elsewhere.

Ball-bearing construction with two-pin power

A ball bearing supports the rotor for consistent rotation over extended use. The two-pin connector supplies 12 V DC power without speed reporting or PWM control, so the fan runs at a fixed rate when connected. Black non-LED blades keep the appearance neutral inside any chassis.

Low power draw and simple thermal role

Rated at 12 V and 0.04 A, the fan draws minimal power from the supply rail. In normal operation it provides steady airflow for component-level cooling while the ball bearing keeps acoustic output predictable. The 10 mm thickness allows installation in slim coolers or restricted mounting points.

Questions about this item

What voltage and current does the 2-pin connector draw?

The fan runs on 12 V and draws 0.04 A through its 2-pin connector.

What are the exact mounting dimensions for this 40 mm frame?

The square frame measures 40 mm by 40 mm with a 10 mm thickness for standard 40 mm mounting holes.

How do I correctly connect the 2-pin plug to the motherboard header?

Align the keyed 2-pin plug with the 12 V header and press straight in; reversing the pins will prevent the fan from spinning.
