I'm thinking of getting some quiet fans for my Quicksilver. I have searched and cannot find any specific details on what are the fan sizes and what kind of fans to use. Most case and power supply fans I find are with the regular 4 pin connector- does anyone have fans that use the same connectors as Apple does? In my case the machine has one hear the processor, one in the case and one in the Power supply. Are they 60, 120 and 80?
