The aquaero has the full-range for the fans (0-12V). Moreover you can control the fans by the power (0-100%) or by the Speed (0 UPM - Max UPM).

as far as I know the Aquaero gives the Fans 12 V for the first few seconds so you should be able to use every fan you want. But I am not sure about that.

Use the fan you want to (I have got fans from "Papst"), some like "Revoltecs" more, ... . It's a question if you want just "normal" fans, some with lightening, some made of Aluminium or some which are extra quiet. With Rev. 4 you won't have any problems, like Rev. 3.07 had, so use what you like best .
As rebyC wrote, the Ae will test the fans at startup two times (100% for a few seconds), then the fans will be regulated to the speed/power-settings you'd choose. The only problem would be, if you control the fans by temperature and they're turned off -> they won't start until there is enough voltage, althoug they can run at lower voltages after the first turns, so you will have to except this or control the fans per speed/upm :-/.

Zitat von »Top_Nurse«

I was actually wanting to control my fans by using the temp coming off the radiator. Can the Ae be programmed to initially start up at say 50% voltage or power and then decrease to a user specified parameter after so much time?

Actually, I have no idea if there is a chance (maybe with a small temperature-range, but then you have the problem to start at, let's say 100% and the fans will decrease back to 0% :-/)
