Desktop GPU Cooling System: open fan motor winding. An internal winding or cable conductor no longer carries current.

The distinguishing clue

The fan remains still despite a valid control command.

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: Check supply, command and tachometer lines before condemning the fan. If confirmed: Replace the failed fan and inspect its cable routing.

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

Related cause to rule out

When rattling, scraping or delayed fan startup changes with orientation, also consider Desktop GPU Cooling System: worn fan bearing before choosing a repair.

Checks after the work

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