Back to my 30W LED project, I have a small northbridge heatsink with a fan on it that I've mounted to the back of my LED.
I'd like to poer it from the LED driver, but it's constant current and pumps out 1A, whereas the fan is only 50mA.
Would there be a way to restrict the current to 50mA for the fan without a drop in voltage? it doesn't move a lot of air so I don't want to slow it down, but it seems to move enough to keep the LED cool.
