I've had this rig for about 2 weeks now I built it myself. Everything was fine it would be around high 50s to low 60s n load and mid to low 30s on idle but then for whatever reason the temperatures starting getting extremely high. I'm not sure if it's because I moved my computer under my desk (That's when it started getting hot). I moved it from under there and put it on top of the desk and it's still having problems. I have a fan blowing directly onto it and that doesn't help at all. So I reseated the fan and the temps got even worse( Mid 50s on idle!!) I can't even play minecraft without hitting the 70s. I have stock settings and stock cooling.
(1) Moving the computer probably loosened on of the locking lugs. To quote an OLD poster Supremelaw, "Intel should be sued" for such a poor design. Many Have problems with installation and The stock HSF is at the BOTTOM of the todum Pole. And yes it will work @stock, but just barely.
(2) ALLways reapply HS Coumpound if you remove the HSF. Can use alcohol to clean off old compound (is Use the 91% found at walmart). And for AS5 - peas size in center then spread evenly.
(3) google installation of the Intel HSF for a video.
