Thermal Throttling at ~80 celsius

[iQuimper]

Hello. A week ago i had my laptop cleaned of dust and the CPU thermal paste replaced and in the last few days i noticed in XTU that my cpu thermal throttles at around 80 clesius. This only occurs sometimes and only in XTU, while in  HWiNFO64 everything seems normal, except "IA:PROCHOT" turning to "Yes". To give you an example when this happens, today i was playing Skyrim and just as soon as my save loaded i was experiencing horrible freezes every two seconds and audio lag. From what I've read on other forums, those freezes might occur because of the VRAM. I am aware that this problem might occur in Skyrim because of the mods that i have installed, but this happens in other games too that aren't necessary very demanding, like Overwatch with everything on low . So my question is, what might cause these performance problems and thermal throttling at only 80 celsius?

 

I'll list below my system specs, also i use a CPU undervolt of 85mV.

Update the bios if one is available. 

And with a 1050 ( assuming it's a 2 gig model ) you'll 90% of times end up running out of vram and page filing. 

Check vram usage.

Sounds like the power delivery is overheating.

It's the 4gb model. A while ago, like 5 months or something, I tried to update my bios with Asus EZ Flash, everything went ok but might have been a dumb choice. Do you think that might cause this problem now?

And how can i fix this?

Highly unlikely. Usually bios updates fix power throttling problem. 

Check vram usage again. Try cleaning the laptop. Dust it off etc.

You can't fix a shit design. From what I remember correctly about the XPS models, Prochoot throttling is the result of the CPU power delivery hitting 125*C and reducing CPU performance so as to not melt the power delivery on the board. It's what happens when the board design is bad and the VRMs are not cooled.

It has just been cleaned, but i ll try to update my bios again

Updated the bio, nothing's changed

So what you are saying is that i can't do anything about this problem, and just live with it?

Then it's probably what @5x5 said..

If that's the case. Sadly not much can be done other than maybe  directing airflow at some part of the pcb.

Sadly, most likely yes.

What exact model is the laptop?

 Thanks both of you for all the help so far. My laptop is an Asus VivoBook Pro 15 N580VD

Then I assume it has an HQ i5 or i7 - go into your power plan settings and set maximum CPU performance state to 99% - that'll disable Turbo boost entirely so you'll have ~2.8GHz but at least it should mitigate Asus' terrible design. Basically, this thing needs cooling on high end parts

I understand, thank you!
