Why is my CPU temperature so high even in BIOS?
Asked by

I've just built a new PC from a well-known company in Denmark, MMVision. It has a 98003xd CPU, a 5070 12 GB GPU, and 16 GB of DDR5 RAM at 6000MT/s. My motherboard is a B850-PLUS II, but I'm not sure about the cooler model. My main issue is that the CPU temperature is sitting at 70°C right in the BIOS. I get that it might rise under load, but this seems excessive! I ran some OCCT benchmarks for both the CPU and RAM without any errors. I also tried playing CS2, where it initially gives me 400+ FPS, but then drops suddenly to 30-40 FPS for a couple of seconds before going back up. The RAM usage is around 70%, which could be a factor, but the CPU seems like the bigger issue. I also noticed that the CPU cooler feels a bit loose. There's a 3-pin cable from the CPU_FAN on the motherboard that isn't connected - could this be causing the overheating? What steps can I take to fix this? I'm not too experienced with PC parts, so I'm worried about making things worse if I try to fix it myself.

70°C in BIOS does sound a bit high! It's usually cooler before anything starts running. Definitely check that fan connection. If you didn't apply thermal paste, or if the cooler isn't seated well, that can cause temp issues. If the cooler feels loose, it's worth checking on that too. Just be careful; if you decide to take the cooler off, make sure you clean off old thermal paste and reapply new paste correctly. You’ll get a better connection and hopefully lower temps!

First off, make sure that the CPU fan is connected properly. If it's loose, that could definitely lead to higher temps. Also, try tightening the cooler a bit more; just a quarter or half turn on the screws might help. It's essential that the cooler makes good contact with the CPU, so check if there's thermal paste applied or if there’s still a protective film on it. If you’re not sure about removing the cooler yourself, it might be a good idea to ask a friend who has more experience or look for some video tutorials online.

ChillTechie: Exactly! And remember, if you take off the cooler, do it gently to avoid damaging anything. It might be scary, but it’ll be worth it for better cooling.
