Love the looks of the new Kraken X62 ... wish I hadn't bought the Corsair H115i, even though the latter is working just fine ... but I like the Kraken more.
I'm going to do a bolt through mod on the H115i as the mount pressure isn't that great ... but really, any of the dual 120mm or dual 140mm AIO's should be fine.
The Thermaltake one gets rave reviews too ... the one with 3 120mm fans, forget the name. If I had the room, I'd go with the Thermaltake.
Best of luck...
