Replacement fan for legacy ATI cards

The OEM Industries FD9238U12D is a 12 V, 1.2 A circular cooler with a 4-pin power connector. It is built as a direct drop-in replacement for reference-design ATI HD4890, HD5850, HD5870 and HD5970 graphics cards. The red LED housing matches the original aesthetic while the ball-bearing motor targets long service life in older systems.

Cooling capacity and headroom

As a fan-only unit rated at 12 V and 1.2 A, it delivers the airflow specified for the listed ATI models under stock clocks. It will handle typical gaming loads on those cards but offers no margin for heavy overvolting or sustained compute workloads that push the original thermal design power higher. The single-fan layout cannot dissipate heat from heavily modified BIOS profiles.

Four-pin PWM interface limits

The 4-pin connector enables PWM speed control so the motherboard or GPU firmware can modulate RPM based on temperature. On legacy ATI boards the header supplies a standard 12 V PWM signal; the fan will not respond to voltage-only control schemes. Builders adapting the cooler to non-ATI boards must verify that their header provides a compatible PWM signal and 1.2 A current capability.

Questions about this item

Will the FD9238U12D fit the mounting holes on my HD 5870?

The FD9238U12D is listed for the ATI HD 5870 among other models, so the mounting pattern matches that card's reference design.

How can I confirm the fan is running correctly after installation?

Connect the 4-pin connector to the graphics card header; the ball-bearing fan should spin up smoothly at 12 V and report speed via the fourth wire.

Does the package include mounting screws or thermal pads for the HD 5970?

The product is supplied as the fan unit only; mounting hardware and thermal interface material are not included and must be sourced separately.
