Replaced the top fan in my PC-V354 case with a noctua 140mm fan to make it a bit quieter.
Well, now that its installed, the CPU fan (FAN4) and the top fan (FAN3) both spin up and down repeatedly. FAN3 reports "Lower Critical 400RPM", then fan3/fan4 spin up to max, and alert clears. Only to repeat 5 seconds later. Continues in a cycle.
Can of course run the fans at full speed and the problem goes away.
Anyone seen 4pin headers with low RPM have this issue? Opened a case w/ SM to see if the rpm is just too low or something and it detects a critial situation.
Tried FANA (based on System temp, not CPU temp) and same deal.
