Why is the Intel CPU heating up on a laptop, replacing thermal paste does not help?

Question

Do it yourself

Good afternoon.
There is an HP G62 laptop, the percent is heated on it. Even goes into a sharp shutdown. In the logs, Windows writes about the huge temperature in Kelvin, in Celsius 98-99 degrees. And the laptop goes out. At rest, the temperature is 68-70 degrees at the processor, according to Everest. I changed the thermal paste, there was almost none of it at all either on the processor or on the radiator .. However - again, when idle, it was already 58 degrees. Which is too much. Working t should be about 40-50 degrees ...
Is the percentage pouring in?
P.S. The AMD video chip was burned a long time ago, now the laptop is loaded strictly on the integrated Intel video.

Answer 1

The cooler can't cope, the heatsinks are clogged with dust, the heatsink is loosely pressed, the thermal paste is a ton of options.
PS In kelvins, measuring the temperature of the processor is strong, but it is not clear why.

Answer 2

Perhaps the thermal tube connecting the CPU to the heatsink has broken.

Answer 3

Let's start with the fact that there really should be very little thermal paste. Thermal paste is only needed to fill microroughnesses between the CPU and the heatsink. Thermal paste is liquid only in a tube, spread it dries very quickly. After drying, the quality of the paste does not change.
In short, you need to change the thermal paste only when dismantling the radiator, apply a thin layer of 0.1-0.2 mm (it will turn out less, good).
There are few reasons for overheating, the main ones are:
1. The radiator is clogged with dust.
2. Dead fan

Answer 4

I have the same problem "Stump" heats up under 100 and this is already the maximum, I lowered the frequency, nothing changed to 99, it fell and that's all and then the new cooling rolled up and everything returned to 20 degrees in idle time on the desktop

Answer 5

pushes hot air back. or percent dies (accelerated). or the capacitors on the board are dying. choice =)

Answer 6

It is possible that the thermal paste that is between the crystal and the processor cover has dried up. There are reviews on YouTube with parsing the processor and replacing the paste.
