I finished my new rig last night and this morning ASUS Probe is reporting my PSU fan at 950 or lower RPM. It was fine last night and some times today it will show 1200 or so. Does Enermax have a built in Smart fan controller in the Liberty series of PSU's.
I dont know much about that, but it seems that your powersupply cant handle your new rig. OR you need to re-enable those features on your motherboard
It could b many things, but i think those might b it
