Zyvpee DFS40105M 40 mm 10 mm 5 V .8 W 2 pin sleeve case fan

Compact 40 mm case fan

The Zyvpee DFS40105M is a 40 mm by 10 mm case fan designed for tight spaces inside a computer chassis. It runs on 5 V power and draws .8 W through a two-pin connector. The sleeve bearing keeps the motor simple and the black frame blends into most builds.

Practical limits of the two-pin interface

A two-pin connector supplies constant voltage without a speed signal or PWM control. The fan therefore spins at a fixed rate up to 1600 RPM and cannot be regulated by the motherboard. Builders who need variable speed or fan-curve tuning should choose a three-pin or four-pin model instead.

Sleeve bearing and day-to-day implications

The sleeve bearing uses a thin oil film that runs quietly at low loads but can wear faster than ball bearings in continuous operation. The 40 mm square frame with 10 mm depth fits narrow mounts such as router enclosures or small-form-factor cases. Two wires keep cabling minimal for cramped routing.
