Just wanted to share something I though of and had good results. I bought a Taisol CGK 742 and found it was a bit noisy. Even more so when I put the 26CFM Y.S.Tech fan of my Alpha on it. I noticed the fins where very easily bendable and still had a 80mm 4500 rpm fan laying around. So I bent the fans à la Zalman and glued the fan on there with a plastic glue gun.
Result where that the cooler became nice and quite and performance improved by a few degrees compared to the Y.S. tech. I have just the in-socket thermistor that gives unreliable results. But the CPU seems to get just a little warmer than the Silverado I currently have on my 1333 Mhz T-bird.
