Laptop CPU Overheat. Reaches Beyond 80°C

Yo! Guys what's up?
My dad has a big problem recently, and is with his HP Pavilion DV6 -1280us.
Its AMD Turion X2 ZM-87 @ 2.4 GHz is Overheating, and reaching mid 80°C temperatures.

I've checked this with Speccy.

Eventually the computer either freezes or Shuts Down (No BSD yet, AFAIK)

Motherboard seems to also get a temperature increase.

The computer was recently cleaned, since it was thought that the vent had been blocking the air flow.

I've tried putting the PC to Power Saver, but nothing.

Wait... I've found the CPU usage is around 90%. I've just killed WD Management engine, which was using 64 - 70%.

I thought, that it was need of thermal paste (which I don't know if the guy who the computer was sent to applied it or not).

I'll post back if that was the main problem.


Edit: Seems I've sorted out the problem. It seems that the WD was the main cause of the Processor Overheat.

Now the CPU has dropped to 55°C which is the normal temperature for the laptop.

Anyways, thanks for the help
