I've been having some issues with my PC's temperatures. Normally, when I'm gaming on ultra settings, my CPU temps hover around 60°C. However, recently I noticed a significant jump—after about 4 hours of gaming, my temperatures shot up to 93°C, despite having the same applications open.
I recently cleaned my PC, so I'm puzzled by this spike. My CPU load stays around 30% max. I'm using an i7 14th Gen processor, which is undervolted since I built it two years ago. I also have Thermal Grizzly Conductonaut thermal paste, which I don't think is the issue since it shouldn't be dried out yet.
My AIO cooler, a Deepcool Mystique 360, is also two years old, and I'm not hearing any unusual sounds from it, so I believe it's functioning well. This problem isn't just during gaming; when I worked last Friday for 9-10 hours, my PC started at a normal boot temp of 38°C but rose to about 80°C after being on for so long. Typically, my working temp is around 48°C at most and it shouldn't peak like this.
I'm currently running Windows Version 25H2. Has anyone else dealt with similar temperature issues?

Have you checked the orientation of your AIO radiator? It's crucial for the pump and radiator positioning to ensure proper airflow. Also, make sure your AIO pump is running at max speed constantly—fluctuating speeds can create issues. You might also want to consider updating your BIOS if you haven’t done it in a while!
If your CPU cooler is on correctly and the pump feels like it’s working, I’d lean towards checking the thermal paste application. A poor application can lead to overheating. Another possibility is the radiator—make sure it’s not being obstructed by case fans. If all else fails, consider re-mounting the AIO cooler.
Sounds like it could be an issue with your AIO pump or fans. If you unplugged anything while cleaning, try double-checking those connections. If you re-seated the cooler, sometimes that can cause poor contact with the thermal paste. Make sure everything's plugged in and running properly!
Thanks for the tip! Just to clarify, the high temps started before I cleaned it. I did use a blower for a quick dust removal, but it didn’t help. I'll check connections again just in case.
The AIO is mounted at the top of my case, and I ensured the pump header is set to max speed. I cleaned without disassembling anything, so the scent of danger was there before cleaning. As for the BIOS, I haven't updated since January last year.
