Desktop GPU Cooling System: poor heatsink contact. Uneven mounting leaves part of a chip without effective thermal contact.

The distinguishing clue

Temperature rises almost immediately under modest load.

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 screw order, contact pattern, pads and chassis deformation. If confirmed: Refit or replace the cooling assembly with even specified pressure.

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

Related cause to rule out

When load temperature is high even with good airflow and fan speed, also consider Desktop GPU Cooling System: dried thermal compound before choosing a repair.

Checks after the work

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