Enermax (fc) or no (fc)

What's the difference? During normal operation is one quieter than the other?

The FC power supplies have Fan Control. The FC power supplies adjust fan RPM depending on temperature.

But I though they all did.

The shortcoming of fan control is that when the fan slows down the case temp goes up, waaaayyy up, until the power supply also gets hot and then the fan speed picks up again. If you're going to be using one of these things be sure you have alternate case exhaust fans.

bump for a good question.

NVS, I'll call you around noon about PC Expo

The bottom 92mm on my Enermax EG365P is controlled with a temperature sensor that you can place about anywhere inside the case. I have mine wedged up against my CPU heatsink. The fan spins pretty slowly even with it stuck there but the 80mm in the rear runs full blast all the time.
