I have found a 400mm - 2x200mm radiator and was wondering if this could be used in a custom loop, the case I purchased has support for 2x200mm fans mounted in the front of the case.. The radiator is a Phobya Extreme 400 (V2).
Thermaltake view 37, I haven't received it in the mail just yet, i read that they do fit 2x200mm fans in the front.
Just keep in mind that radiators require some extra clearance on both ends. I guess that this is the one you've looked at: Phobya Xtreme 400 - V.2 - Full Copper. Its specified length is 445mm.
Well if the fans are directly next to each other it will fit
