Replacement fan for HD 7750 and HD 7770

This frameless cooler is built as a direct drop-in for the reference graphics cards HD 7750 and HD 7770. It serves repair technicians and owners who need to restore original cooling performance without modifying the board. The unit is a fan-only assembly with no heatsink or mounting hardware included.

Thermals noise and power draw

The sleeve bearing runs on 12 V at .5 A through a standard 4-pin connector, allowing the graphics card to control speed automatically. In normal operation the fan spins only when the GPU temperature demands it, keeping acoustic output low during idle and moderate under load. Power consumption stays minimal, drawing just enough current for targeted airflow across the existing heatsink.

Build quality and daily implications

The red frameless design saves space inside tight card profiles and avoids interference with nearby components. A 4-wire PWM connection enables precise speed curves, so the cooler ramps smoothly instead of jumping between fixed steps. Buyers who need a different voltage, a larger frame or a complete heatsink assembly should look elsewhere.

Questions about this item

How do I install the 4-pin connector on this frameless fan for an HD 7750 or HD 7770, and which step is often missed?

Align the keyed 4-pin plug with the graphics card header and press firmly until the latch clicks; the step often missed is verifying the latch is fully seated so the PWM signal and 12 V .5 A supply both make contact.

What maintenance will the sleeve-bearing fan need over time?

Sleeve bearings cannot be relubricated easily; when noise or vibration appears, plan to replace the entire FD8015U12S unit rather than service the bearing.

What limit appears first when this 12 V .5 A fan runs continuously on an HD 7750 or HD 7770?

The sleeve bearing’s wear rate is the first limit under sustained use; expect rising noise and reduced speed before the motor or frame shows any issue.
