Ordered a Corsair 650D and would like to put a 140.2 rad in the roof. Specifically the "Hardware Labs Black ICE Radiator GT Stealth 280". http://www.overclockers.co.uk/showproduct.php?prodid=WC-021-BX Which 140mm fans would you guys recommend? I know that rad has a high amount of fins, so guess it will need good air pressure. But I'm struggling to work out what's best. I would like the fans to be silent though, probably run through a fan controller too.
