HP 470 G7 constant temp spike and overheating issue

[rocksolid87]

My wife has a HP 470 G7 notebook for work (Intel Core i7-10510U). It’s been having a consistent random core temp spike of 100 C and sometimes shuts down due to the spike in temperature. I’ve been having her monitor the temps with Core Temp. Nothing that is being done on this computer even comes close to putting any strenuous load on the CPU as it’s used mostly for typing documents (yes, overkill I agree). I’ve disassembled it, cleaned it, replaced the fan and thermal paste. The fins and all air intake holes are completely clean as is the fan. I first used Zalman STC7 paste, but after that made no difference I cleaned it off and applied Cooler Master CryoFuze. After that still made no difference I replaced with fan with a new one identical to the original. The temp still seems to be spiking to 100 C. The PC receives proper ventilation, but that doesn’t seem to make any difference.

Any idea why the temp is spiking and overheating like this? Anything else I can try to remedy the issue?

Forgive me if I’m just simply misunderstanding, but are you saying you’d rather members either post here alone or go elsewhere?

No that is not what @phillpower2 is stating.

What if you do what you are instructed here counter reacts what they are having you do or bricks the working system. Happen more than one thinks.

Plus, you are out of pocket to replace the parts.

While cross posting in social media is fine doing it and following instruction on several technical forums can and have turned into a disaster for users.

Now if you have not received an answer from a forum in let’s say 24 hours then by all means post it and reference the fact that you have posted and not received any response in x amount of time.

Hope this helps.

No worries and in answer to your question, no, I have replied to you on another forum and as per the above explanation advises to avoid accidents people should not follow advice from more than the one forum at a time, it can lead to a blame game if something goes wrong, all forums have such etiquette and will likewise always point people in the direction of another forum if/when they cannot help.
