Suits owners repairing that specific tower

Builders maintaining a Dell OptiPlex 3050 MT can install this unit without adapters or wiring changes. It is not for other Dell models, custom builds, or systems needing different dimensions, voltage, or connector pinouts.

Questions about this item

What motherboard header do I need for the 4-wire 4-pin connector on this SUNON MF80201VX-Q060-S99 fan?

A standard 4-pin PWM fan header on the motherboard supplies the 12 V power and speed-control signal this fan requires.

Will the 80 mm x 80 mm x 20 mm frame fit the same mounting points as the original W52D3 fan in my OptiPlex 3050 MT?

Yes, the dimensions match the factory W52D3 cooler, so the four screw holes line up with the existing chassis brackets.

How can I confirm the fan is running at the correct speed after installation?

Check the RPM reading in BIOS or a hardware-monitoring utility; it should report a stable value once the PWM duty cycle is set.
