110mm Blower Fan for Server Power

The Zyvpee BL4447-04W-B49 is a 110mm case fan built with a blower housing that directs airflow along a narrow path. It runs on 12V power through a 4 pin connector and uses a ball bearing for durability. The 110 by 28mm frame fits server and industrial chassis that require this specific form factor.

Suits tight server bays.

This fan suits administrators upgrading or repairing 1U and 2U server power modules where a 110mm blower is specified. Builders assembling standard desktop towers or GPU coolers that expect a conventional axial fan will not be able to mount it. Buyers who need addressable lighting or a different mounting pattern should look elsewhere.

4 pin PWM connector decides motherboard control

The 4 pin power connector enables pulse-width modulation speed control from a compatible header. If the target system only provides 3 pin voltage control, the fan will run but speed regulation may be limited. Verify the header type before purchase.

Questions about this item

Will the 110mm by 28mm frame fit my server power-supply bracket?

The fan measures 110 mm square and 28 mm thick with a 4-pin connector, so it matches standard 11028 blower mounting holes used in many server PSUs.

How do I wire the 4-pin connector so the PWM control works?

Plug the 4-pin header into a 12 V PWM fan header on the motherboard or controller; the fourth wire carries the speed signal and PWM duty cycle.

When should I plan to replace the ball-bearing blower?

Ball bearings run continuously at 12 V; monitor for rising noise or vibration as the indicator that the fan is nearing end of life.
