I have one and all I can say these units are much more then the specs. OCZ was very conservetive when they listed those.

They run strong and keep it cold till 4700Mhz on a Q9650 with heavy stability tests like Linx and Prime95. Much more then I wished for really.

I'm moving to Ln2 soon so keep an eye for a nice unit with very little use shipped anywhere in USA with the upgraded Duniek hold down plate on the FS thread.
