Desktop CPU Cooling System: incorrect fan or performance profile. Software or firmware commands an unsuitable balance of heat and fan speed.

The distinguishing clue

Temperatures or throttling change sharply between power modes.

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: Compare approved profiles and reset only the relevant thermal control. If confirmed: Restore the correct profile or firmware after hardware cooling is verified.

Repair boundary: Repair the confirmed fan, pump, mounting, compound or airflow fault before extended load.

Related cause to rule out

When the fan runs at full speed constantly or reports an error despite spinning, also consider Desktop CPU Cooling System: fan control circuit fault before choosing a repair.

Checks after the work

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