Desktop GPU Cooling System: incorrect thermal interface material. The wrong pad, compound or thickness prevents even contact between a hot component and its cooler.

The distinguishing clue

One component overheats after a prior repair while airflow remains normal.

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 interface type, coverage and thickness with service information. If confirmed: Fit the correct compound or pad without stacking random materials.

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

Related cause to rule out

When temperature rises almost immediately under modest load, also consider Desktop GPU Cooling System: poor heatsink contact before choosing a repair.

Checks after the work

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