Compact 40 mm server fan

The Zyvpee FFB0412EHN BL2R is a 40 mm by 28 mm case fan built for server CPU cooling. It runs on 12 V and draws 0.40 A through a three-pin power connector. The black frame houses a ball bearing for continuous operation.

Straightforward three-pin fit

Installation is a direct plug into any standard three-pin header; no adapters are required. The 4028 form factor leaves little room for error, so verify the mounting holes match your bracket before securing the screws. Incorrect orientation will reverse airflow.

Suits tight 1U and rack builds

This unit fits builders who need a 40 mm replacement for dense server chassis or compact industrial enclosures. Buyers who want PWM speed control, larger frame sizes or RGB lighting should look at other models.

Questions about this item

How can I confirm the 40×28 mm fan is spinning correctly after connecting the 3-pin header?

Connect the 3-pin connector to a 12 V header, power on the system, and verify the blades rotate smoothly; the ball bearing should run quietly at the rated 0.40 A draw.

What comes in the box and do I need any extra cables or mounts for the FFB0412EHN BL2R?

The package contains the 40 mm × 28 mm black case fan with its attached 3-pin lead; mounting screws and any adapter cables are not included and must be sourced separately.

Which version of the 12 V 0.40 A 4028 fan should I choose for a server CPU cooler?

The FFB0412EHN BL2R is the single listed variant with ball bearing, 3-pin connector and non-LED black frame, matching the 12 V 0.40 A specification for server CPU cooling.
