Jo because I'm gonna give my two cents ... So I bought last month a XFX Radeon HD 6850. After the stock cooler but so unbearable was loud and Furmark temperatures up to 90 degrees zulies needed a new radiator. Since the card from XFX but does not match the reference design turns out the search a bit difficult. I have previously tried a Gelid Icy Vision rev. To install 2, however collide since the heat pipes from the radiator with components on the graphics card. So after a long search, I chose the Arctic. The installation is very simple, but the curing of the supplied thermal adhesive for the passive heatsink bit annoying. 5 are indicated hours !! Drying time, but I would let dry the card rather longer because it can happen that otherwise dissolve the heat sink again. Everything is assembled and dried Should the cool super work: If the fan rotates at 100% it is still relatively quiet and I get at Furmark only a maximum of 65 degrees ... 25 less than the original cooler ... However, there are something negative: on my card is the GPU relatively far to the right. That causes that the weight of the mounted radiator draws the card down. Looks just not as great when the graphics card is seated imbalances in the housing ... Otherwise everything was great.
