I have used a Corsair H60 since June. Yesterday I replaced it with a Corsair H80 (ignore my sig, it doesn't cover my X-mas upgrades). I'm a huge fan of this line. Easy installs, no absurd pressures on the mobo AND you can actually use all of your RAM slots.
I guess I will keep this thread instead of make a new one.
I decided to grab the 800D and the H100 looking for 120mm fans I hear good things about the AP15 but I don't like the white fans I would jump on them if they were black.
Either way I will try the stock fans on the H100 unless that is highly unrecommended but I still have a spare 120mm slot on the top of the 800D to fill
I have been using the stock fans on my H100 which I bought a week ago. I keep it set on "medium" and am actually really impressed, they are quiet even when I ran prime95, much cooler and quiter then my H60 with 2 yateloon's.
