Hi, Gotkevlar
quote, (
If I take off the cover of my rig, it does NOT lockup)
Try as Elemental_dragons post,
You may have 4 case fans on your case, but how are they configuired?, for best results, front should suck into the case and the rears blow out of the case,
You may have a dead spot in the airflow that is allowing temp to rise in that one component causing your problem of lockups,
If it is stable with the side panel removed But, locks up with it on, you have an airfow/cooling problem
Regards
