I need the quietest Cooler for a i7 6700k. I am doing a very quiet build. I have looked at Noctua nh d14 and nh d15. Which is the quietest? Which Cooler would you go for If quiet is very important? I will not overclock it in the near future, maybe in some Years. I actually dont know If i am getting the i5 6600k or the i7 6700k though. I will use the pc for gaming. Need answer before black friday, thanks
