just recieved the new Silverado HSF from England. I am running it at the 12 volt range. It is reasonably quiet and I can imagine it would be considerably quieter using the 6,8,or 10 volt ranges. The problem is that my CPU still idles at 45c with 2 80mm case fans and the power supply fan going. I expected a lot lower temps. I am running an AMD t-bird 1.2 not overclocked. I used the thermal paste that came with the fan. It might run cooler with some Arctic Silver but I doubt it. This thing is HUGE. I am worried about the Horizontal load on the Socket A on the Abit KT7A-raid Mobo. Well, if it falls off I will have to regroup. Does anyone have experience with this HSF?
