Good afternoon.
There has been a problem with this Vaio (vgn-cr41zr) for quite some time now.
With any more or less strong load, it starts to heat up wildly, Everest shows the CPU temperature is more than 90 degrees, after which the laptop turns off.
The BIOS lacks PC Health and cooler / overheating protection settings (BIOS is very cut off, only the simplest settings). At the same time, no programs for working with coolers and changing the speed of their rotation simply see this same cooler.
I took it apart, blew the inlet / outlet grilles of the cooler on the case with a vacuum cleaner, changed the thermal paste - to no avail, the thermal paste is enough for a week, after which overheating occurs again. It feels like it simply “burns” the thermal paste (I don’t know how to explain this), because the next time the laptop is disassembled, it becomes noticeably smaller. I tried different thermal paste - both KPT-8 and Alsil-2 (if it matters).
Hence the question - are there any other ways to fight, or is there only one way - to the Service Center?

Of course, with such abnormal behavior, it is best to go to the service, but as an alternative “at least some” option, you can try overclocking on the contrary and a laptop stand.
The first is in the BIOS or special. program (of which there are many) to change the frequency or even the voltage on the processor down (after all, the processor should be seen). By the way, maybe the BIOS settings have gone astray and the percentage has begun to receive pressure beyond measure?
Secondly, many laptops cannot cool properly when working on their knees, a blanket, and even sometimes a flat, even surface. A laptop stand will facilitate air access or even create forced draft (cooler).

There is only one way - to the service center.
I remember once my laptop started to overheat and nothing helped.
After changing the cooling system - again peace and order.

Hello, first check that the cooler is spinning. Secondly, when you changed the paste, did you change it on the video chip as well? Thirdly, it is possible that the passive cooling mode is set in the Windows cooling settings. Fourth, try Arctic Silver paste, MX2 - for example and above. I have it in a laptop for 2 years on average. Fifth, you may have lost the thermal pad when you changed the paste and now there is a large gap between the processor and the heatsink.
