MY 3570k seems to be running hotter than it should. In a 75 degree room. its topping out at 70c using prime95. I don't have an overclock on it. Using evo 212+. Fan is set up to push air through heatsink towards back. I've redone the heatsink paste three times with no change. my case has 2 front intake, 1 back exhaust, and 2 unused top vents. Any ideas?
