Experiencing Frame Drops and High CPU Temperatures After Moving My PC

Hey everyone! I recently relocated my PC to a different room, and now I'm dealing with some serious frame drops while gaming, and even on the desktop. I noticed this issue especially after long gaming sessions. I've tried lowering my graphics settings, but that only made things worse, dropping my frames by about 30. I did my homework online and ended up trying a bunch of things: lowering settings, restarting, reinstalling drivers, and using HWMonitor to check my setup. When I opened my PC, I discovered that my CPU temperature was alarmingly high, hitting around 98-100 degrees Celsius. That seemed way off, so I made sure the cooler was properly seated and cleaned out any dust. Even after all that, my framerate improved a bit, but the temperature was still high, plus one of the fans started squeaking.

In HWMonitor, the CPU was the only thing out of whack. I decided to turn off one GPU setting (DSR factors), and the temp dropped a bit to 89-91 degrees. Lowering my resolution to 1440p helped more, bringing it down to 67-79 degrees, which is better, but still not ideal. I'm considering replacing the CPU cooler, but I'm confused about how to test or swap it. I followed some instructions that suggested stopping the fan to check for noise, but I don't see an obvious fan on the CPU cooler.

Now that I've removed the CPU cooler, my PC is silent, but the CPU temperature hasn't changed much—still sitting around 69-79 degrees at idle. This is puzzling because I expected the temperature to spike without the cooler. I truly believe the CPU cooler is the problem, but I'd love to hear if anyone has any other insights or thinks I might have misdiagnosed the issue! Here's my setup: Intel Core i7 10700F 2.90 GHz, Nvidia GeForce RTX 3060 12GB, and 24GB RAM.
