Laptop 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

Use the laptop on a firm surface with its vents unobstructed. Record whether exhaust airflow and fan noise change during normal work; stop after a thermal shutdown.

Stop point: Do not run heavy workloads when the fan is stopped or exhaust air is absent.

Workshop confirmation and repair

Device-level check: Record fan speed, temperature and workload, then inspect the complete air path and mounting.

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, heatsink, pad, compound or control fault as one cooling path.

Related cause to rule out

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

Checks after the work

After repair or replacement, check idle, processor load, fan response, sleep and cooldown.
