Desktop GPU Cooling System: external airflow obstruction. Soft surfaces, covers, damaged feet or poor case placement block designed intake clearance.

The distinguishing clue

Temperature improves when the intended intake and exhaust clearance is restored.

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: Inspect feet, filters, case position and the complete external air path. If confirmed: Restore the designed clearance, feet, filters or damaged covers.

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

Related cause to rule out

When fan speed rises but exhaust airflow remains weak, also consider Desktop GPU Cooling System: dust blockage before choosing a repair.

Checks after the work

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