Thanks for all your help with my last question. I've got my Gridseed working and I'm mining BitMiles and HamRadioCoins. So far, so good. The thing now is I'm not sure if too much power is going to the Gridseed. I'm using a 12V 6A power supply and the gridseed starts to get warm to the touch after running for awhile. The fan is supposed to be cooling the gridseed. Should I be concerned and use something less like a 12V 5A power supply?
It's impossible for a device to get "to much power". Volts are are pushed, amps are pulled. Meaning it will always output 12 volts, however, the amount of amps pulled is determined by the devices and will pull NO more than it needs. If you power something with a 12v 6A power supply and it needs 12v 5A it will only use 12v 5A. In other words the volts are constant, the amps are variable based on need.
Now if you power a device with say a 15V power supply and it only needs 12V, it will likely burst into flames regardless of the amount of Amps pulled (unless it has some kind of voltage regulator in it).
