BurnOutPC.com has posted their review on the Arctic Cooling Accelero S2 Heatpipe Videocard cooler.

Well, I'm pleased with the results. But I was not so happy about the compatibility issues this cooler has. If Arctic cooling made the mounting bracket just a bit larger, than it would be compatible with cards like the Jetway and Sparkle without a problem. Another problem I had were the fins touching the parts on the video card. An increase in height from the cooler would make things a lot easier and again a lot more compatible with all sorts of cards. The Accelero S2 comes with lots of bits and pieces which is great, the heat sinks make life for the memory a little bit cooler and the Arctic Ceramique is a nice addition although you don't have to use it since the cooler comes with pre-applied thermal paste.
