So, I was installing a new heatsink about 3 weeks ago and for some reason my comp didnt work afterward... So, I returned the mobo, and got another one, figuring I had damaged it during the installation... NOW, all is working fine EXCEPT.... I am getting an alert on the asus probe....it is saying, Chasis fan below threshold!! What the heck does this mean? and how do i fix it? I am thinking it has something to do with the PSU....but i dont really know... On the mobo i plugged a 3 prong power into the Cha 2 fan slot....this didnt fix the problem... Any help would be MUCH appreciated...thanks! Chaz D.
