just wanted to share this... is your Notebook acting like a radiator, bursting hot air into the room while it's already damn hot anyway?
In my case, simply using a vacuum cleaner on all the ventilation holes and the keyboard worked a mircacle. The additional use of a CPU limiter software reduced the noise to zero and the heat to a minimum.
BUT check the cooling fans (if there are any) for clogged dust bunnies that were sucked into the fan. Kills off components in a matter of few minutes.
I wrote this because my boss almost killed his PC by vacuum cleaning it. The GPU fan was clogged and broke down so the GPU ceased working and the machine did a emergency powerdown.
Another point is people using their laptop in bed or on other soft surfaces - don't do that! It hinders air flow a LOT!
Do you hear popping sounds when the machine is hot? Check electrolytic capacitors with the cross mark on top on the mainboard - if that surface is cracked, the capacitor is damaged; this triggers random malfunctions and shutdowns and might also kill other components.
