Dell M5786 Heatsink Fan Assembly

The Dell M5786 is a replacement heatsink and fan assembly built for the OptiPlex GX280 desktop. It fits directly into that chassis to cool the processor and maintain stable operating temperatures. This part suits technicians or owners repairing or maintaining that specific legacy system.

Direct replacement for GX280 cooling

The assembly installs as a direct swap for the original cooling unit in the OptiPlex GX280. It handles the thermal load of the processors supported by that platform. It does not fit other Dell models or custom builds requiring different mounting patterns or airflow profiles.

Questions about this item

Will this heatsink fan assembly fit the OptiPlex GX280 I already have?

The M5786 is built specifically for the OptiPlex GX280 chassis and mounting points, so it installs directly without adapters or modifications.

How can I confirm the M5786 is spinning correctly after I install it?

Power on the system and watch the fan through the case vents; it should start immediately and run steadily, and the BIOS hardware monitor will show a valid RPM reading for the CPU fan.
