[FIXED!!] need help with weird cpu temperature spikes

[aremicchi]

hello. ever since yesterday i've been having a problem with my cpu. whenever i open an app/program or do an action, my temperatures spike up. for example: refreshing desktop makes cpu spike to 70 celsius. opening chrome is 97, restarting windows explorer 100, etc etc. on a game it stays at 90-100. idle is going around 50-80. when i restart my laptop, it stops spiking like this. but on the first boot after closing my laptop completely, it definitely happens. my normal temps are 50 on idle, max 70 on any game.

changes i've done before yesterday are enabling secure boot state from my bios (for riot vanguard), and updating to 24h2 (win11). i'm unable to rollback the update.

cpu boost is always disabled. i dont see anything using the cpu too much either.

things ive tried:

resetting bios settings to default (both general and security settings)
performing clean boots (the situation is the same. first boot has temp spikes, after restart it stops)
disabling secure boot

i want to avoid reinstalling windows so i'm open to anything.

FIXED: reinstalled windows, problem was the 24h2 update. currently using 23h2, everything is fixed.

How old is the CPU thermal paste and what type is it (oh, I read it's a laptop so yeah, those can get a bit hot and sometimes the fans build up dust or stop working, then you have the issue with the heatsink itself, when the tiny amount of liquid dries up in the pipes) - I mitigate heat by using a laptop cooling fan/pad and if you are technically/mechanically inclined, you could change out the (possibly garbage) factory thermal paste.

The real problem with laptops are the tiny fans that they use are not proper, especially for "gaming" laptops as a lot of heat generates; therefore, the viscosity and thermal breakdown of that thermal paste happens at increased levels as opposed to a desktop.

Perhaps best to ask how long have you owned the laptop and if this is a new issue?

What apps are you using to Monitor the temps?

Do you allow the cpu voltages to be left on Auto? Never so that. Manually lower them.

Your apps could be wrong. At around 95*C then it should be thermal throttling the cou clocks, is that happening at all?

As I had mentioned in the post, this isn't a cooling issue. It only happens on the first boot, fixes after restart. The thermal pastes are new. Fans are working well. After restarting, I see 70 celsius max once again. The laptop is able to cool itself. Still, thank you for your answer.

HWMonitor. I did consider it to be wrong but I didn't see the need to use another app after noticing that I was also having FPS drops due to high temperatures. So it /does/ spike, for sure. I don't manually control the voltages, but I don't see the need to do that either. It's all fine after the restart, after all. I just want to understand why this happens on the first boot.

Out-of-date BIOS/UEFi

I've recently sent my laptop to services due to another problem. The motherboard was changed and I made sure the BIOS was up-to-date because there is no way to manually update it, since updates aren't given by the manufacturer. Is there nothing else that might be causing this? Or any other solutions?
