EK-FC6970 AcetalProduct Review (submitted on January 16, 2011):
I got 2 of these blocks straight from the source and I can say the fir and finish of the product is great. It took no time to get these on my 2 Sapphire 6950's. the adapter they give you that you are supposed to use on the copper side I could not get on, no matter how hard I tried, but besides that they keep the cards very cool I have had a hard time going over 42C. I would recommend these to anyone who has xfire in their system as if you stay with stock cooling you better have a MB that allows you to keep the cards a good distance apart or you will soon cook one of your cards.
Great fit and great cooling. Highly recommended
