It should run hottest during tests like prime95 or aida, should run a bit cooler while actually using real programs like gaming. How hot is it getting during games? It may shorten the lifespan some if running at 80c all the time, for regular use (not testing) I'd prefer to run around 70c or under at the top end.
To give an idea, it's 28c in my pc room right now. My dark rock pro 3 is keeping my 4690k at 37c, 35c, 36c and 35c at idle. It's oc'd to 4.6ghz with a vcore set just under 1.29v. Just played far cry 3 for about 10min running various scenarios, firefights, driving etc and topped out at 67c, 65c, 65c and 61c across the 4 cores under a typical gaming load.
