Well, maybe not but it is something to think about...
I took a look at the Arcticooler review on HardOCP (http://www.hardocp.com/reviews/cooling/arctic_ca/index.html)and noticed that Kyle's readings were with the CPU at (most likely) full load. Then I looked at 2Cool's review (http://www.2cooltek.com/socket_test.html) and it looks like his temp readings were taken at idle. But the interesting thing was when I read a post on this forum (http://forums.anandtech.com/messageview.cfm?catid=37&threadid=233690) of bmg's personal experience with an Arcticooler. He compared it to his Alpha I believe. With both the Alpha and the Arcticooler the idle temps were the same, it was not until a full load was applied that the Arcticooler kept the CPU cooler than the Alpha.
