Query: Incredible Cooler

This cooler is fantastic. The build quality is very very good, and it dropped the temperature of my ATI Radeon 4850 video card from 70C down to 36C.It's also whisper quiet.I'm definitely building this brand again.Installation was very easy. One word of warning: you should buy the heat sink paste cleaner kit and clean the old paste really well, on both the graphic chip as well as the memory chips (the latter will be cooled by the small aluminum heat sinks which come with this product).I bought the Arctic cleaning solutions for that. Quite often people also buy the Arctic Silver heat-conducting paste. I just used the zinc paste which came with the product and I didn't have any troubles with it.
