Hey everyone! I just built a new PC and I'm a bit worried about my 7700X's temperature while in the BIOS. Here are my specs: AMD Ryzen 7 7700X CPU, Noctua NH-D15 cooler, Asus TUF B650-E motherboard (BIOS v. 3263), a Gigabyte 3080 12GB GPU, 32GB T-Force Vulcan DDR5 RAM at 6000MHz, a 2TB Samsung 990 Pro NVMe SSD, a Fractal Design Meshify 2 case, and an EVGA SuperNOVA 1200 P3 PSU. This CPU is supposed to run hot, with a max of 95°C, but seeing it idle at 83°C in BIOS is concerning. Usually, in Windows, it fluctuates between 54°C and 95.9°C even with the case open. I used a decade-old tube of thermal paste and noticed that one side of the cooler screws in faster than the other. Could it be unevenly seated? However, it runs fine in Windows. In BIOS, the fans ramp up, and the CPU just stays locked at 83°C. Is it normal for this chip to behave like this in BIOS? What temperatures do you get? Should I reseat the cooler or reapply the paste?

It's definitely not normal for the CPU to stay so hot in BIOS. Typically, that's when it's at idle temperatures, so I'd lean towards it being a sensor glitch. Maybe someone with the same ASUS motherboard can shed more light on this!
Hitting 83°C in BIOS is way too high! Your thermal paste might not be working anymore, especially if it's that old. You could also double-check that you removed any plastic film from the cooler. If it stays at that temp and doesn't fluctuate, it could just be a weird sensor issue or something with the motherboard's readings.
I used an old NH-D15 too, but I cleaned it really well and made sure there was no plastic film left. Even with old paste, the temps shouldn't be that high, right?
I suspect it's an issue with your ASUS board too. I'm using the same setup, and my temps in BIOS are way lower.
