VRM temperature issues

[vininhosts]

Good morning!

 

Yesterday, I took apart my PC in order to clean it. Now that I rebuilt it, the VRMs are getting very hot, to the point where it throttles the CPU. All fans are working and blowing air to the same direction. I believe it's the VRMs because it is not Windows related, since I installed a new  version, it's not the BIOS, because settings are the same, and the CPU temps never go over 70C.

 

I am using an I7-9700, Corsair H60 and an ASUS TUF H310M Gaming Plus

Get Intel XTU and see what it's actually happening, It will offer you detailed info about your CPU. It may just be a bad thermal paste application

I could see on HWMonitor that the throttling happens when TMPIN3 reaches 56C. I guess that indicates the vRMs are getting too hot?

TMPIN3

from what I found online it's a "TMPIN 3 = Sensor near GPU/VRMs". When cleaning your pc did you take out your GPU or CPU? Try reseating the GPU first.

Power components can safely work at really high temperatures, like 100+C will be totally fine. If you look at datasheets most of them have 175C maximum.

What you have are just assumptions and nothing more, you need to measure component temperatures if you want to be sure. Otherwise you might spend a bunch of time trying to solve an issue which does not exist.

Ok then so what else could it be? Because drivers are up to date, BIOS as well, temps don't go over 70C, thermal paste has been reapplied 3 times and windows has been updated and reinstalled

And what is happening exactly? Define "throttles". What the frequencies are, how they change and when etc...

OK.

 

I start running Cinebench. Everything is normal in the beginning. After about 3-4 minutes, when TMPIN3 reaches 56C, I see the clocks on about 3-4 cores go from 4.5GHz to 3GHz. From then until the end, those clocks continue, but the throttled cores vary (sometimes Core #1 is throttling, sometimes it isn't)
