Compact 40×40×20 mm case fan

The Zyvpee FD054020EB is a 5 V, 0.32 A axial fan built for tight spaces inside computer cases or network equipment. Its three-pin connector supplies power and a tachometer signal for speed monitoring. Dual ball bearings support continuous operation in a square DC cooler layout.

Suited for small-form-factor and embedded builds

This fan fits 40 mm mounting holes and low-profile brackets where larger coolers cannot go. It is not intended for high-airflow CPU towers, radiator stacks, or builds that demand PWM speed control or illuminated blades.

5 V three-pin power requirement

The unit draws 0.32 A from a 5 V header, so the motherboard or controller must provide a compatible 5 V three-pin socket. Without that exact voltage and connector the fan will not run.

Questions about this item

Will the 40×40×20 mm frame fit my router's fan slot?

The fan measures 40 mm square and 20 mm thick, so it fits any 40 mm mounting pattern with at least 20 mm clearance.

How do I connect the 3-pin lead to a 5 V header without reversing polarity?

Align the keyed 3-pin connector with the header's missing pin; the fan runs on 5 V at 0.32 A and the key prevents backwards insertion.

When should I replace the 2-ball bearing fan?

The 2-ball bearing design lasts longer than sleeve types; replace it when noise increases or airflow drops noticeably.
