Zyvpee 110mm Blower Fan

The Zyvpee BL4447-04W-B49-71 is a 110mm blower-style case fan designed for server power supplies and compact chassis where directed airflow is required. It operates on 12V DC with a 2.0A current draw and uses a four-pin power connector for PWM control. The unit features a black frame and non-LED construction with ball bearing internals.

Installation Notes

The fan measures 110 by 28mm and uses a standard four-pin connector that fits typical server or motherboard headers. Ensure the mounting holes align with 110mm spacing and that the blower orientation matches the intended exhaust path. The ball bearing design reduces friction but requires correct voltage polarity to avoid damage.

Sustained Operation

Under continuous load the ball bearing maintains consistent rotation without the wear patterns common in sleeve alternatives. The 12V 2.0A rating supports steady airflow for server power supply cooling over extended periods. Blower geometry focuses air through restricted channels rather than open fins, sustaining pressure where axial fans would stall.

Questions about this item

How can I verify the blower fan is spinning correctly after connecting the 4-pin power connector?

Check that the 4-pin connector is fully seated on the motherboard or fan controller header, then confirm the fan RPM appears in BIOS or monitoring software at the expected 12V supply.

What comes in the box with the Zyvpee BL4447-04W-B49-71 and do I need any extra mounting hardware?

The package includes the 110mm blower fan with its attached 4-wire 4-pin cable; mounting screws for the 110mm frame are not supplied and must be purchased separately.

Which version of the 110mm blower should I choose for a server power supply that requires 2.0A at 12V?

Select the BL4447-04W-B49-71 model rated at 12V 2.0A with ball bearing and 4-pin PWM control to match the server power supply specification.
