40 mm Delta server fan

The Zyvpee FFB0412UHN is a 40 x 40 x 28 mm case fan built around an original Delta 4028 motor. It runs on 12 V and draws 0.75 A through a standard four-pin connector, providing DC speed control for precise airflow management. The two-ball bearing is chosen for long service life in continuous operation.

Suited for tight server chassis.

This fan fits 40 mm mounting holes in rack-mount servers, compact workstations or embedded appliances where space is at a premium. The four-wire PWM interface allows the motherboard to regulate speed automatically. Buyers who need larger airflow volumes or near-silent running in a home PC should look at bigger frame sizes instead.

Two-ball bearing for continuous duty

The dual-ball bearing construction resists wear better than sleeve alternatives when the fan spins twenty-four hours a day. That mechanical choice is the primary indicator of whether the unit will survive the intended workload without premature failure.

Questions about this item

How do I mount the 40x40x28mm fan and which 4-pin header do I use?

Align the four screw holes with the chassis fan mounts, secure with standard 40mm screws, then plug the 4-pin connector into a 12V PWM header so the speed signal works.

When will the 2-ball bearing need replacement?

The dual ball bearing is rated for long continuous operation; expect service life of several years in a server chassis before noise or vibration signals wear.

What thermal limit appears first during sustained 0.75A load?

At 12V and 0.75A the motor hits its current ceiling before the frame temperature becomes critical, so the fan maintains speed until the supply or header limits current.
