My PC's temps suddenly gets higher the longer it is running

Hi, I've been experiencing some issues with my PC recently. The temps are usually at 60°C when I am playing a game on RT Ultra. I noticed 3 days ago, after 4 hrs of gaming - with the same applications open - my CPU temps would rise up to 93°C.

I am not sure what is happening since I just cleaned my PC. The CPU load is 30% max.

I am using i7 14th Gen though but it was undervolted since it was built 2 years ago. As for the thermal paste, I am using Thermal Grizzly Conductonaut, so I don't think dried thermal paste is the issue.

My AIO - which I also bought 2 years ago - is Deepcool Mystique 360. I am not hearing a rattling sound, so it should be in good working condition.

The issue is not limited to when I am gaming. When I was working last Friday, my PC is on for 9-10 hrs. Normal boot temp is 38°C (ambient temp 26°C), after I finished my job (which is mostly some browser and MS Excel open) I noticed that the temperature was about 80°C. The usual temp when I am working is 48°C (highest).

Current Windows Version is: 25H2

Anyone else encountered the same issue?
