High temperature spike on idle

[enderman712]

I got back to my gaming pc after it was hibernating overnight and then I see that my idle temperature was 76 degress celcius I waited for a few minutes because I thought it was just my corsair aio needing to spool up or something and I open the app and it was running at high speeds so I could tell something was wrong. I open task manager to see "PresentMon" at the top of my cpu usage list. I killed the process and my temperature dropped by 30 degrees near immediately
It was a file present in the Nvidia FrameViewSDK
I ran an antivirus scan and no results came up

This is absolutely unacceptable behavior for any software to exhibit if there any fixes please let me know.

system specs:
Ryzen 9 5900x
H100i elite capellix xt
RTX 4070 SUPER 12gb gddr6x
16gb ddr4 2666mts
asus TUF 570x gaming plus (wifi)
850w 80+ gold

I confirm all of this, it just happened to me browsing the internet (Google Chrome) and having accidentally enabled the Nvidia overlay (RTX 3070), the fans of my PC, which is quite silent, started making noise, particularly the CPU (Ryzen 5 5600X). I looked at Ryzen Master and the two main cores were at full use alternating each other, raising the temperature even more than the heaviest application I use for the CPU.

What kind of garbage is this?

After upgrading PresentMon to v2.2.0 (embedded in HWiNFO), we're also getting reports of high load after running for some time. Seems like something gets stuck in PresentMon resulting in excessive work loops.

So it seems like that's where my issue is coming from. I use HWiNFO all the time for my StreamDeck and then magically out of nowhere my temps spike, and it starts using like 30% of my CPU usage. Then I have to force close PresentMon in Task Manager. Hopefully they have a fix in the works soon for PresentMon.

So you're running both HWiNFO (with the PresentMon sensor enabled) and Intel PresentMon in parallel? That could be another problem.

That's possible however I didn't even have anything open and nvidia overlay was disabled and PresentMon was on the task list and I genuinely thought it was a virus until I found this page for its legitimate use

I also ran into this issue. After the NV APP auto update to the newest version the PresentMon have sign by Nvidia. Also have this issue and have 2 cpu thread have 100% load.

Has been a problem for me as well.
