Loool well I have thought about that as well I am either going to make a heater pad up for testing and then stick the unit onto my own 64 setup as I know basicaly what temps I get from my GT I will tune it that way or just get a test pc with a nice hot chip thinking maybe a pally they run nice and hot and I do have a cheapo setup at home I can drag in and use as a test machine the prob is if I overcharge the units then you will all have to clock the crap out of your cpus so the mach wont plink lool
