Default Power per fan or pump

How much power does each fan take? Is it all that much?? And how does it compare with water pumps?

Anyone know some stuff about this?

Multiply the amperage rating by the voltage

An example would be a .25A Lafan 80mm which uses 12volts, which is 12 x .25 which is 4 watts. This is a pretty power hungry fan too.

My 2 fan controlers have 18watt channels. So im guessing it dont get much higher then that. If your going to do air cooling, make sure you get a nice fan controler. Make life much easier.
