Bizarre temperature changes.

Hello everyone!
I'm having a bit of a issue with my computer, not sure what is causing the problem but the issue is very weird.
I was playing cyberpunk on my pc, it would usually run at 70C GPU and 70-80C CPU.
The temperatures of my CPU would usually fluctuate quite a lot. Idle would be 45C and while browsing somewhere around 50C. It was very common to rise by 10C for half a second to drop right off. It would rise up to 75C on certain games. So while I was playing cyberpunk my pc froze for a second showing no display on my monitor and then it just rebooted. My first thought was that the cpu overheated and shut off. Which was worrying. The weird things started to happen afterwards though. There is quite a few minor issues that I noticed with the temperature from that point on, like for example the temperature being very similar regardless of my fan setting in bios, but that biggest thing for me is how the games run. Now the CPU while being in game like Divinity original sin 2 runs at around 55C when it used to run at around 70 just yesterday, overall most of the games I play have the CPU running cooler, but unfortunately I feel like some of the performance is also gone. Games that used to be locked at 165fps now fluctuate a lot between 130-165 which makes the game not run as smooth as it used to, and that seems to be the issue with a lot of them. One game actually runs better than before. It is something unusual that is why I'm writing here to see what thoughts anybody may have. The only thing that comes to my mind is the power, maybe the cpu isnt getting enough of it? I tried running prime95 and the wattage seemed to be alright. My system would run very hot when doing the test though hitting 90C or more during small FTT. My Cpu was never overclocked.

Any ideas of what happened would be appreciated.

Here is my components:
Intel Core i5-10600K 4.10GHz (Comet Lake) Socket LGA1200 Processor - OEM
Asus ROG STRIX B460-F GAMING (Socket LGA 1200) DDR4 ATX Motherboard
ASUS ROG Strix LC Performance AIO CPU Liquid Cooler - 120mm
Team Group Vulcan Z T-Force 32GB (2x16GB) DDR4 PC4-24000C16 3000MHz Dual Channel Kit - Grey
MSI GeForce RTX 2080 Super Gaming X Trio 8192MB PCI-Express Graphics Card
Samsung 970 EVO Plus 500GB M.2 2280 PCI-e 3.0 x4 NVMe Solid State Drive
Seagate 4TB Barracuda 5400RPM 256MB Cache Internal Hard Drive (ST4000DM004)
Asus Strix SOAR 7.1 PCI-E Sound Card (90YB00J0-M1UA00)
Leadex II 750W 80 Plus Gold
 
An Update.
Tried several things including a system reinstall but didn't help.
Games run at high fps but very unstable and I have big drops from 140 to 80 fps.
I run latencymon as I saw it being suggested online. This is what it showed me:

I'm not sure where to go from here considering I reinstalled all the drivers when I installed a fresh windows.
Could this be my aio failing and so cpu is throttling?
 
They're both lower than anandtech's numbers, so there's definitely something up.

I'd start with a full bios reset and take it from there. Remember to check your memory speed and that your FCLK is running in 1:1 mode.

It's possible your aio is bad - any unusual noises? I'm not familiar with Asus' cooler, so I can't say how reliable they are. That said, it's only 120mm and I'd be tempted to switch it for a 240mm at least.
 
Hi, thanks for trying to help!

I did already try resetting the bios with the touching 2 pins with paperclip method and it did not help.
Im not sure where to look for FCLK in the bios, what I can tell you about my ram is that its running at 2666 mhz because thats the max my motherboard allows. (Lack of information on my part when buying it.)
The aio is indeed making a weird scratching noise, the temperatures dont rise above 65 when playing games though, could that still be the problem?
 
From your description it does sound like your CPU isn't being properly cooled, yeah. If it throttles due to heat that could cause your framerates to drop.

Grab GPU-Z if you don't have it already, and make it log to a file (on the sensors tab) while you play a game.

You can use a program called Generic Log Viewer (https://www.techpowerup.com/forums/attachments/genericlogviewer_v5-4-zip.170633/) to graph the log files it produces.

Look at the times when the framerate drops, and see if they are in sync with CPU temperature going too high - fortunately GPU-Z records the CPU temp too.

You could also tell from this if the GPU is overheating and throttling - look at the GPU clock figure.

Thanks for the suggestions.

I did the exact steps but I couldn't notice anything out of the ordinary in the log file, not sure if its because I just dont have the knowledge to see the problem or is it actually completely fine.
My game drops frames every second basically but the cpu temp fluctuation doesn't seem to correlate to that, the temps for CPU topped at 68C (same goes for gpu that topped at 66C).
What I did notice is that my CPU temperature overall is fluctuating quite a lot even when just browsing.
At this point after trying all possible software fixes I'm quite confident its some kind of hardware issue. Not sure if its PSU, cooler, CPU or the GPU.

I'll include a link to the file in case you'd like to take a look yourself.

Sending my system off for warranty repair. Hope they will figure it out and swap the faulty part.

Thanks for help guys, appreciate it.
