Gaming Laptop Cooling System: fan control circuit fault. The motherboard cannot command or sense fan speed correctly.

The distinguishing clue

The fan runs at full speed constantly or reports an error despite spinning.

Checks before an assessment

Record the game, power mode and time before throttling or shutdown. Do not continue a game to reproduce a fault when airflow is absent or the machine is excessively hot.

Stop point: Continued gaming through thermal shutdown can damage the battery and board.

Workshop confirmation and repair

Device-level check: Log processor and graphics temperature, clock, power and fan behaviour during the same repeatable scene.

Targeted check: Compare temperature, command and tachometer behaviour. If confirmed: Repair the controller or sensing path after testing a known fan.

Repair boundary: Repair the specific airflow, fan, heat-pipe, pad or control problem and repeat the game workload.

Related cause to rule out

When fan speed rises but exhaust airflow remains weak, also consider Gaming Laptop Cooling System: dust blockage before choosing a repair.

Checks after the work

After repair or replacement, check processor load, graphics load, game load, fan modes and cooldown.
