So i'm thinking of picking up some high speed/high cfm fans. I have a few questions.
Would it even be worth it to get 1 or 2 38mm thick fans for my Megahalems? AKA would i see a big improvement in temps over my 2 CM r4's, and would it give me any more oc headroom?
Are Delta's or Panaflo's worth it, or should i just get some Ultra Kazes and hope the sleeves don't wear out to fast?
I feel like a huge noob asking these questions

, but i'm just thinking for benching air when i can't do sub zero.
