How did your install go Numpsy?
Getting the cpu block screwed in was a bit of a pain (holding the block in place and getting the first screw in need a bit of force!), but fine otherwise - nice how it doesn't fill up the whole case!
As far as noise goes, I can't hear the pump when the fans are running at standard speed, but if I set them to Quiet mode on Gigabyte software then I can hear a buzz over the top of the fans(not very loud, just stands out a bit).
I haven't had chance to have a real go at overclocking it yet, but the gigabyte auto overclocking app took it up to 4.2ghz and hit around 50c while doing it.
This is using it with the stock fans - haven't tried others yet.
Actually, I'm thinking about getting a pair of Orange Phanteks PH-F120SP LED ones to go with the case lighting, not sure how they compare for effectiveness though?
