ok, it does reach above 70 C, but the fans speed up significantly when that happens. normally it reaches 70-71 and then the fans bring it down to about 65 C.
running a full scan of MSE (over an hour, i had 180GB to scan) caused 72-75 C on the four cores, and 78 C on the CPU package, but those were very temporary, the fans sped up and dropped the temperature quickly
default 'high' preset, with reduced shadow quality (lush grass, lush trees and more grass tank my FPS in the rift if shadows are high detail) and no AA (not really needed at 1080)
