Okay, so here is what I tried. I have an HP case that I Moded. I added a 90mm intake fan located on the bottom back and the only other fan was the 120 fan on the PSU for exaust, note I have a gtx 460 which cuts off air flow though my case. My core temp hit 73c. I turned my 90mm fan around to make it exhaust and added an 80mm intake fan to the side. That dropped the temp down to 66c under load. Any other ideas that might help?
