I'm running that exacted setup curently with a 4.8ghz overclock with 1.35v. At idle its around the 34°c on the package, on full load stress test with adia 64 it maxed out at 69°c after 15 minutes but i have seen it occasionally hit 72°c when running CPU intensive games for a few hours but only for a few seconds before cooling down again. On my H100i I've got my pump running max speed 2900 rpm and ive binned the the standard fans for two corsair SP120 fans running at 1300 rpm, as the standard fans sound like jets taking off when the raditor starts to get hot. At idle the water temp is at 29°c with the room amibent at 25°c and after 2 hour intense gamming it will hit 39°c .
Hope this helps
