Is it true that when the video card of the laptop becomes critically overheated, it will always warm up later?

Question

Do it yourself

Friends, hello everyone!
I gave the sony vpcz12v9r laptop to the service, due to the high temperature without load, they shrugged their hands in the service, they said that in case of a critical overheating of the video card, it will now always warm up above the norm, to be honest, I’m not sure about this thesis, tell me the service specialist is right?

Answer 1

except perhaps if the tempopaste has deteriorated due to severe overheating, but in this case it is enough to change it and that's it ..
critical overheating can cause the chip to "fall off" when contact with the board is lost and the video card stops working (or starts to artifact). heating should not be affected.

Answer 2

In some videos there is a blade of the cover. Symptoms are the same: overheating even without load.
I saw a repair of a similar video on YouTube on the channel "CoRE: Center of Repair Engineering".
The case is nasty, long and unguaranteed. Many people find it easier to solder a new video chip.
UPD. Found a video at home. https://www.youtube.com/watch?v=044CyNRR2FE

Answer 3

Lol, no. It doesn’t mean) they disowned you either because they can’t solve the problem according to the conditions to which you agree or because there is no problem. Tell me all the background, then it will become clearer what happened

Answer 4

that with a critical overheating of the video card

Chips of nVidia, Intel, and recently AMD processors cannot overheat in principle, as well as motherboards that have a built-in overheating warning system and a forced shutdown if it is detected.
I omit the description of other modes as the temperature rises, such as skip cycles, frequency reduction, etc.
