I just upgraded my system from an ab350 itx to a B550 Phantom Gaming ITX/ax. My issue is that the new motherboard can't seem to detect or control my CPU fan speed. Doesn't seem to matter what fan header it's plugged into or what fan settings I change in BIOS. This, of course is resulting in the CPU temps get pretty warm while doing anything even moderately intensive.

I'm on BIOS 1.8, and the fan is a Noctua NF-A9x14 PWM.]]> Sat, 23 Jan 2021 05:08:21 +0000 https://forum.asrock.com/forum_posts.asp?TID=17876&PID=83339&title=b550-phantom-itx-ax-cpu-fan-speed#83339
