Well, I just bought a Be Quiet Dark Rock Pro: Be Quiet Dark Rock PRO BK016 CPU Cooler - Scan.co.uk
and it is excellent! But I cannot stress just how huge it is...
I have a big case, and it just fitted in (I couldn't slide in the motherboard tray from the rear, how to remove the motherboard tray bottom rail, slide up the tray, reinstall the bottom rail whilst holding up the tray in some precarious maneuver, and then the case side fitted on with literally half a centimetre to spare.
But despite it being huge, and being the most evil looking cooler I have ever seen
, I love it (but it sounds like an aeroplane at full power - which fortunately it rarely reaches)
