Is this the correct place for tech issues/help? Having a serious, out of nowhere CPU heat problem that has me pretty concerned and looking for some advice. I know there was another thread floating around but I couldn't find it and had this one bookmarked. If it's cool to post issues here (build is about 2 months old) I will reply with the details. Very confusing.
Alright thanks. So, funny the 5800 is getting attention this page, when that is the CPU I am having issues with! Just a brief blurb on my setup:
Phanteks P400A
Ryzen 5800X with/Noctua NHD15
Gigabyte Aorus B550m Pro-P
Crucial Ballistix 3600 MHz DDR4 16GB (8GBx2) CL16 BL2K8G36C16U4B (X2)
Zotac GeForce RTX3080
800W Silverstone Gold-rated PSU
1x500gb Crucial SSD
1X2TB Crucial SSD
1x4TB Western Digital HDD
So, the setup - I don't overclock anything except change BIOS settings so my RAM will properly run at 3600MHZ. I got the thing built and running great on the first try and that surprised me. Performance was great, and other than EGS glitch with the AMD 5xxx series that caused heat to spike, the heat levels were great with the Noctua and the default 5 fans in the Phanteks. It would idle, even with my typical (and admittedly absurd) 50-60 Chrome tabs open at anywhere from 38-50deg Celsius, typically in the low 40s. Games would spike up to the 60s, 70s for demanding games - the only game I ever saw take it above 80degrees was Warzone, but it would typically sit right around 80 and lower. I would almost never hear fan noise, so it was fantastic.
Then I went on a short trip where I had the PC switched completely off while gone, came home (3ish weeks ago) and then realized I was hearing more fan noise than normal. I hadn't had Ryzen master on for a week or so because I had forgotten to turn it back on to monitor temperatures. I randomly flipped it on one day because I heard so much fan noise and realized the temperate was in the high 80s - I then tested benchmarks on multiple games - Division 2, Borderlands 3, Metro Exodus, Horizon, and more - the temperature was up near the maximum limit of 90deg celsius (or at that mark) in almost every benchmark. Then I started noticing even playing games like FFXIV, or less intensive games the temp would also go up to high 80s/90 flat.
I am now at the point where as I type this the temperature is fluctuating just below or hitting the 90'c max, and with no games or applications running in the background my CPU is showing at 4,000+ mhz (typically is below 1000mhz when just browsing the web). All my settings are on auto and have not been changed. I have never overclocked. The PC has not been moved, bumped into, or damaged. It was seated properly with an adequate amount of thermal paste purchased for its efficiency.
I have restarted multiple times, checked my task manager and tried to close other programs, and have not seen much change. Fortunately games still work pretty well - I get a lot more random FPS drops than before this happened so clearly performance is suffering, but I guess the overall power of the system keeps things running pretty well.
I am mostly worried that at this point I am risking lasting damage to the internal components or the CPU because of this. I was scared of reports of excessive heat with the 5800x but like the poster above could not get the 5900 so settled on this in the interim. I am willing to do a full Windows reinstall if necessary, and while I desperately don't want to undo my entire desk setup and take the PC apart, I will do that if that is the recommendation to try to fix the problem.
Oh- last thing - the PC is in a well ventilated area and none of the fan enclosures are blocked. As I said, this issue was non-existent for nearly two full months of daily operation.
Thanks for any help you all can give, I just have no idea what to do at this point.
PS: BIOS is driver updated, GeForce drivers are updated. GPU temperatures appear normal when running games/tests according to MSI afterburner, so I am fairly certain this is almost entirely a CPU heat issue.
