i've heard the OCZ Gladiator is good, although many members have qualms with that company, an equally good replacement is the Millenium Glaciator, of which i'm in the process of getting(was going to get the gladiator but after talking with a few members on this board regarding OCZ's customer service, decided to switch) I'm running a Duron 800 and a Tbird 1.2.....grabing one for both...they're both about the same price(40), but the glaciator cooled better by one degree in a review i read. good luck picking a good one, and as mentioned before, don't skimp
