Replacement fan for HD 7750 and HD 7770

The LORDWORLD FS1290-AP084C is a 12 V four-wire cooling fan designed for HD 7750 and HD 7770 graphics cards. It suits owners of those specific models who need a direct replacement for a worn or noisy original cooler. Buyers with different card models or mounting patterns cannot use this fan.

Mounting constrained to 39 mm hole spacing

The fan frame measures 85 mm in diameter with mounting holes spaced 39 mm apart. Only graphics cards that match this exact hole pattern and voltage requirement will accept the cooler. Installers must verify their board layout before purchase because no adapter bracket is included.

Fluid Circulative Bearing for quiet operation

A Fluid Circulative Bearing reduces friction and acoustic output during extended use. The four-wire connector supports temperature-controlled speed regulation by the graphics card. This combination targets reliable airflow with minimal mechanical noise over the component lifespan.

Questions about this item

Which FS1290-AP084C version fits my HD 7750 or HD 7770 card?

The fan is built for HD 7750 and HD 7770 models with an 85 mm frame and 39 mm mounting holes, so match those two dimensions to your existing cooler.

What does the 12 V rating mean once the fan is installed?

It draws power directly from the graphics card’s 12 V header, so the GPU controls speed without an extra cable.

How does the 4-wire PWM interface limit speed control in practice?

The fourth wire carries a PWM signal from the GPU, letting the card vary fan RPM precisely instead of running at a fixed voltage.
