Which fan header did you plug the fan into?

It connects to the CPU fan header. I verified that. That’s why I’m confused about how it can’t be adjusted.

What's the CPU temperature? Have you attempted to restore default BIOS configurations? Would you consider reattaching the fan header? SpeedFan is quite outdated; FanControl would be a better option if available.

CPU temperature stays within normal range, around 35-40°C at idle and 50°C during web browsing, and 80-90°C while gaming. The cooler isn't designed for this level of heat output. I attempted to adjust fan speeds via the header, but it didn't respond or control the fan at all. After reseating the header, no improvement was noticed. Eventually, I switched to using the system fan 1 header, which performed well. I modified the fan curve and BIOS settings, and it now adjusts smoothly—spinning down at idle and up under load. So I decided to skip the original header entirely. Oof.
