OK....so I just finished this build extremely happy so far i7-930.
Running Prime now core at 4.ghz with vcore at 1.328v this is reading from CPU-Z my temps are 79,78,76, 74 at load, and idle is 39c, 35,38, 36 realtemp.
H-50 single fan air being pulled in. HT is on I may try a little less vcore and see if it remains stable.
