My friend juveduke has a silverado. Apparently it is a great cooler and really quiet (not to mention that the fans are adjustable). Only cons are that it is like $70, tall and heavy, and has a two clip prong (I wouldn't take a computer like that back and forth to lan parties). I personally have a Thermalright AX7. Great cooler, better than the alpha as far as cooling, but only with fans with high cfm ratings, starting to wish I had gotten an alpha instead though because it would have been an excelent cooler even with one of those 25 cfm panaflos. Main reason I had gotten the ax7 was to have better cpu temps without having all my case fans running (just wanted only one exhaust), so it was the wrong fan for my choice because the ax7 really comes alive when you have lots of air flowing. If I only had one case fan running (top exhaust) I would probaly have idle 44*c and load 48*c. Whatever you want to do is up to you. I like what mystif recomended. Think that some of the presure problem with the ax7 would be solved if a square rubber pad (with 80mm hole in the middle and 4 holes for screws) were used to replace those rubber gromets. More air would be directed to the hs and whatever needs to come off will escape through the fins only (where you want the air to go). By the way, unlike the alpha, the ax7 is a heatsink that works better if cool air is being blown on it (thus having a fresh suplly of cool air from those intake fans is very beneficial.
