coastie65 :
I agree with the Cooler Master 212 EVO. I am running a Gelid Tranquillo on my i7 6700k and it does well. If the CPU starts running at 100% which it has been doing of late for some reason that I have yet to find, the temp will get up to around 53c while playing the Witcher 3.
100% during the Witcher 3? Sometimes during loading or in the UI it spikes to 100% for me, but during gameplay it doesn't get much higher than 25-30% IIRC. Also, 53C is REALLY good for a load temp, if that's really at 100% load that's insane. Mine (NH-U14S) will get 67C max (in the summer, ambient 27-30C) in stresstests.
But yeah, if OP is looking for budget coolers the 212 or M9i would be decent choices.
