Is there a way to turn the GPU off when the monitor is not running?

I don't see why the GPU fan should be working long hours when I am downloading stuff and the monitor is off ?!,help please..

You video card is always being used, not until you shut your system off. So regardless it being idle the graphic card needs constant cooling. Usually cards clock down when not in use so it saves power, as for the fan you can control it yourself and drop the speed (rpm)

Just because you turn your monitor off does not mean that the GPU stops sending a signal down the cable.
