With stock cooler i used to have temps up to 85-90C, now using Corsair H60 and temps dropped down to 65-70C while gaming. i7 4790K processors tends to run a bit hot. Make sure your PC case is cooled very well if you're going to stick with stock Intel cooler.
since Ivy Bridge intel Stopped to use soldering between CPU Die and I.H.S, so new processors tends to get a little bit hotter, is a problems that stills on Devil's Cannyon, Broadwell, haswell and as far as I know skylake has the same problem…
So stock cooler may handle just a normal use, for gaming use, better get a aftermarket cooler,
I've ran my i7 with stock cooler and temps were like 90's then put water cooler, temps were max at 70, then delidded that dude … temps never goes up 60 and stays on 26-30 at idle,
The stock cooler is crap in general, and it doesn't matter what CPU you're running. Using that "thing" will give anyone high temps.
