So here's what it's doing to my one-fan setup......I set speedfan to 85% on that one fan channel. When you startup, the fan runs at 100% voltage until Speedfan loads, at which time the fan-speed is automatically reduced to 85%. This assures the fan starts spinning.
The fan itself is a 120mm PowerLogic thermal-controlled fan from CompUSA. At about 24C ambient it starts up about 1150rpms. It idles about 1230rpms, and at 100% load speeds up to about 1360rpms. This gives me CPU temps and PSU temps (only one fan here) around 40C max. Almost perfect. I'm happy......
