I've been going through the hoops trying to find a HSF that would cool my AMD2100. I finally had a buddy of mine turn me on to the Vantec TMD. This fan and heat sink combo dropped my temps from the mid 50's down 7 to 8 degrees into the 40's. It runs at near 5500 rpm and is the most quiet fan I've heard in a long time, about 35-38 decibles. I am using a Raid Max case and an Abit KD7-RAID board. This darn thing has always run way too hot for my liking and I just could'nt take it anymore. Using Artic Silver III, Round Vantec Cables, and this HSF. I'm really pleased with it. Retail is about $30.00 US and it's worth every dime !
