Hi, I hooked up my XaserIII case fans today and when I turned the power on nothing happens. Some fans are hooked up in a chain and connected to fan2. I connected the ends of the chain to the power supply which is a Thermaltake 480 silent purepower. Now, I did not have power connected to the mobo because I am just setting the computer up. I have a case open switch which was open, but I held it closed when I powered the unit on. Are these swithched on automatically by the thermostat?
