Corsair H70 Hydro Series CPU Cooler Review
 

The good news is that the Corsair H70 is a hell of an improvement over the H50. This is not just a re-skin with a larger radiator. The whole assembly has been rethought in partnership with Asetek to deliver cooling performance on par with and better than most of the high-end after market cooling solutions available today. You get a larger radiator for more cooling "capacity", you get not one but two fans for use in a push-pull configuration and a new pump/waterblock assembly that combine to get within striking distance of the NH-D14.
