There is an electrical device designed for this purpose sold at Fry's here in Central Calif. It is described as a "Heat pump", get cold on one side and hot on the other, plugs into the 5V connector & costs around $20.00.You will probably find it wil the cooling fans & accessories. AMD needs about 31x31mm and goes between the chip and the heat sink. So far my AMD6/350 is a happy camper @ 400Mz. CC
