Hey everyone! I recently faced a pretty alarming problem with my CPU heating up to 99°C, which shocked me since my PC is only a couple of years old. I was gaming on 'Lords of the Fallen' with medium graphics when I started noticing some serious FPS drops. After quitting, I switched to 'League of Legends' for comparison, only to find my FPS dropping to 15 at times, even hitting 1 FPS! When I checked my CPU temperature, it was still at 99°C, which freaked me out since I've never dealt with overheating issues before. I thought I bought a solid rig, so I was pretty scared.
To try and fix it, I did some updates and tried a few fixes suggested by a friend: switching my power settings to balanced, disabling Peer-to-Peer sharing, scanning for malware (which came up empty), and even disabling Cortana through regedit. After a restart, everything seemed to work perfectly fine—my FPS in League shot up to 800 when uncapped! My friend mentioned he had CPU overheating issues too, but his case was really hot while mine always felt cool despite the CPU reading.
Now, I'm really curious—why did these changes fix my issue? What exactly caused the overheating in the first place, and how are my games running smoothly again? Here are my specs if that helps:
Windows 11 Pro 64bit,
12th Gen Intel(R) Core(TM) i7-12700KF (20 CPU's), 3.6GHz,
32GB RAM,
Nvidia GeForce RTX 4060 Ti 16GB,
Cougar Poseidon GT AIO Liquid Cooler,
Gigabyte MB Z790 Gaming X AX motherboard,
Kingston 16GB 5200MHz DDR5 RGB Fury Beast RAM.

Your CPU running hot isn’t uncommon, especially with high-powered chips like the i7-12700KF, which can heat up quickly under load. It sounds like your cooling setup is decent, but sometimes things like driver conflicts or power settings can cause weird performance issues, like overheating or low FPS. The power setting switch to balanced is a good move since it can help regulate performance without pushing your CPU to max all the time.
As for why the fix worked, it might be a combo of resetting some settings and keeping your system from working harder than it needs to, preventing overheating. Just keep an eye on your temps with something like CPUID Hardware Monitor and feel the pipes on your cooler to make sure it’s working as it should. If it gets hot again, you might want to check that AIO cooler.
Yeah, when I noticed my temps spike, I had to dive deep into my cooling setup too. It’s wild how minor changes can have such a big impact. Definitely keep monitoring those temps!
