Replacement GPU Turbine Fan

The OEM Industries F8025B12UB is an 80x25mm turbine-style cooler designed for specific legacy graphics cards. It operates on a 12V 0.35A 4-pin PWM connector with a ball bearing for durability. The red frame distinguishes it visually while the 4-wire control allows automatic speed regulation by the GPU.

Suits owners of HD4890, HD6970.

This fan matches the original form factor and connector for those models, making it a direct mechanical swap. Builders repairing other GPUs, or anyone needing a standard case fan, should look elsewhere because the turbine housing and mounting points are card-specific.

80x25mm turbine form factor

The compact radial blower draws air through the heatsink and exhausts it out the rear bracket slot, a layout that only fits the listed reference designs. Verify the original cooler dimensions and screw spacing before ordering, as no other compatibility is implied.

Questions about this item

How do I install the F8025B12UB fan on my graphics card, and what step is often missed?

Connect the 4-pin PWM connector to the GPU fan header, then secure the 80x25mm frame with the original mounting screws; the step often missed is verifying the red blade orientation matches the heatsink airflow direction.

What maintenance will this ball-bearing fan need over time?

The ball bearing is sealed and requires no lubrication; if noise or vibration appears after extended use, replace the entire F8025B12UB unit as the bearing cannot be serviced.

At 12V and 0.35A, what thermal limit appears first during sustained load?

The motor draws 0.35A at 12V, so the first limit under sustained load is the fan's maximum RPM ceiling; if the GPU heatsink cannot dissipate heat at that airflow, temperatures will rise.
