Desktop CPU 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

Note whether temperature rises quickly after startup or only under sustained CPU work. Keep the case closed and avoid load tests if the cooler may be loose or the pump has stopped.

Stop point: A loose cooler can allow unsafe temperature rise within seconds.

Workshop confirmation and repair

Device-level check: Compare pump or fan speed, cooler mounting, case airflow and processor power under a controlled test.

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 confirmed fan, pump, mounting, compound or airflow fault before extended load.

Related cause to rule out

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

Checks after the work

After repair or replacement, check idle, processor stress, fan or pump speed and cooldown.
