I just got myself one of those thermaltake silent heatsinks and it's good. temps seem to be pretty much on par with coolermasters jet 7 wich costs more and is damn noisy. My temps on the jet 7 were 45-46c when set on a pretty high/nosy level. Even on low speed I found the noise of the jet 7 anoying. One question though. When I put on the thermaltake one I put a very very thin layer of artic silver 5 on the die. Is it possible not to have enough on? The layer I put on was very thin so I'm a little worried. temps seem really good though.
