mine idles at about 30 31, ran aida64 for an hour last night and went to 40c.
Really impressed running a Phanteks PH-TC14 as well brilliant cooler.
Only running at 1.25v 3.6ghz on my 1600 though but can't grumble at those temps. for gaming the extra heat from overclocking not really worth it.
Yep ,Phanteks PH-TC14s is my Fav Air Cooler , used it on the I7 4790K & 7600K, Also & Keeps really cool .
I also got a Noctua NH-D15S Dual Radiator Quiet CPU Cooler But that is only 2/3 c More Better Temp & takes so much room up ,
That Cooler really only benefits the x99 Socket High end OC to Get full potential out of the cooler.
