my cure was to put both of my cpu fans on aux 1 & 2 fan controller heads and those two work with no problem at all when you change the settings....just put another fan sensor on the cpu controller head to keep the board from shutting down.
Thank you. Can I just disable the shut-down and beep for the CPU fan if I put it on a different header?
