I'll be running a i7 6700K and planning on overclocking (for gaming use etc, not competitions) I have some very strict requirements (due to the case setup etc) - radiator thickness that cannot exceed 30mm - radiator must be a 240 or 360 format (not 280) - available locally (ideally) So as much as I'd love a Corsair, given it's 30mm radiator that's a risk whereas one with a 27mm radiator gives me that all important whisker of extra clearance. So my choices come down to: Cooler Master Nepton 240M Liquid CPU Cooler ($139. God that tubing is ugly) or Silverstone Tundra TD02-E Liquid CPU Cooler ($129) or Thermaltake Water 3.0 Riing RGB 240mm AIO Liquid CPU Cooler ($185, so a bit of a step up) I'd even consider the 360mm version but at $249 that's really getting up there. But if there's a compelling reason.... I welcome suggestions as to which of these to avoid or go for. If you have personal experience - all the better.
