Direct GPU Cooler Replacement

The SXDOOL FD8015H12S is a 75 mm hydraulic-bearing fan built specifically as a replacement cooler for the AMD Radeon VII graphics card. Each unit runs on 12 V at .32 A through a standard 4-pin connector. The pack contains three identical grey fans with no LED lighting.

Restores Original Cooling Performance

These fans replace worn or failed original coolers on the Radeon VII, restoring the airflow the card was designed around. The upgrade is worth it when the original fans develop bearing noise, vibration or reduced RPM that lets GPU temperatures climb under load. They are not suited for other graphics cards or case-mount positions.

Mounting Pattern Limits Compatibility

The 39 mm centre-to-centre mounting hole spacing and 75 mm by 15 mm frame dictate fitment; the fan will only install on coolers that match those exact dimensions. The 4-pin header provides PWM control, but the card’s firmware governs the speed curve. Buyers must verify both measurements before ordering because the same GPU model can use different coolers.

Questions about this item

What are the exact mounting-hole dimensions for the 75 mm frame?

The centres are spaced 39 mm apart in a square pattern, matching the original Radeon VII cooler layout.

How do I connect the 4-pin header without damaging the board?

Align the keyed notch on the plug with the tab on the graphics-card header, press straight down until it clicks, and avoid bending the delicate pins.

When should I expect to replace the hydraulic bearings?

Hydraulic bearings typically run for several years; plan a swap once you hear new rattling or notice RPM dropping under load.
