Frameless 75 mm graphics-card fan runs at 12 V, 0.25 A via 4-pin connector
This 12 V 0.25 A frameless fan measures 75 mm by 75 mm by 10 mm and uses a 4-pin power connector. It is designed as a cooling fan for graphics card heatsinks. The copper heatsink material and lower noise operation suit repair or upgrade work on compatible video cards.
Technicians replacing a noisy or failed cooler on a card that accepts 40 mm centre-to-centre mounting holes can install this unit directly. Builders whose board uses a different hole pattern or a larger fan frame will need a different cooler.
The 4-pin power connector is the single specification that determines whether this fan matches the graphics card header. Verify the card’s fan header pin count before ordering.

The fan pulls 0.25 A at 12 V, so it adds roughly 3 W to the header load — well within the typical 1 A limit of a standard 4-pin GPU fan connector.
The fourth wire carries a PWM signal from the graphics card, allowing the GPU BIOS or driver software to vary the fan speed automatically based on temperature.
The fan has four mounting holes on a 40 mm square centre-to-centre pattern; measure your existing cooler to confirm the same spacing before ordering.
