Super quiet. Everything is black and looks bad ***.
Case is amazing to work in with excellent cable management.
Able to play Witcher 3 at 1080p on ultra.
OC'ed CPU by 16% and able to get the GPU up to 1450mgz and it's memory up to 7800mgz with no issues at all, giving me about +12fps.
Got this for $75 on NewEgg and it awesome. Yes, it is gigantic and needed to be carefully installed, but it is dead quiet, with killer low temps and looks better than any other cooler out there.
Zero problems with this board so far. It has everything I need and nothing I don't. Able to get a 16% overclock on my i7-4790k.
