Thats good to hear since I am getting a Trupower 430W. I wondered at that. They probably swith between 7v and 12 v depending upon the temperature sensor in the PS. Works well since the temperature in there "should" be just a bit higher than the case temp. I rfeally wish I knew if the fan controlls were stepped or actually adjusted the voltage linearly with temperature. The latter is proabbly to much to ask though.
I've measured the voltage on the fan only connectors on a True380 and a True480. The nominal voltage is a little over 5V and it raises sort of linearly up to a max of about 10.5V. Things have to get pretty toasty (over 40°C in the case) before the fans start speeding up though. They almost always run at 5V.
