I read all the reviews and decided to purchase it myself. I have a Duron 650@950 on KT7 Raid. I have been using the Radio Shack stuff. When I put on the Arctic Silver, my cpu temperatures go up!!! After a few minutes of Seti, it reaches 46. The Radio Shack stuff never passes 44. I've tried applying the silver stuff twice with similar results. Went back to the Radio Shack stuff and it's back to the lower temperature. What is going on here. All the reviews say it's the best thing out there. I have an Alpha also...any ideas?
