Desktop GPU Cooling System: incorrect fan or performance profile. Software or firmware commands an unsuitable balance of heat and fan speed.

The distinguishing clue

Temperatures or throttling change sharply between power modes.

Checks before an assessment

Record whether visual artefacts, fan noise and loss of video occur together. Stop graphics load when there is excessive heat, a burning smell or a stopped fan.

Stop point: Stop graphics-load testing if artefacts combine with excessive heat or burning smell.

Workshop confirmation and repair

Device-level check: Log graphics temperature, hotspot, clocks and fan speed while checking case airflow and card condition.

Targeted check: Compare approved profiles and reset only the relevant thermal control. If confirmed: Restore the correct profile or firmware after hardware cooling is verified.

Repair boundary: Repair the fan, heatsink, pad, compound or controller fault confirmed on the graphics card.

Related cause to rule out

When the fan runs at full speed constantly or reports an error despite spinning, also consider Desktop GPU Cooling System: fan control circuit fault before choosing a repair.

Checks after the work

After repair or replacement, check video output, graphics load, fan response, hotspot and cooldown.
