I've had both the OCZ & the corsir domibator cooler. The OCZ is imo mobo jewlerry, pretty but does nowt. The Corsair by comparison:-OCZ dedicated memory cooling
1) easier to fit & remove
2) Far better cooling.
I bought the ocz originally thinking 2x45mm fans would be quiter & more effective than the 3x60mm on the corsair, but sadly it ain't so.
Luck with build
