But turn the speed controller up and it sounds like an airplane taking off

Depending on what im doing i can adjust for maximum cooling or minimum noise or anywhere in between infinate varibility not stepped or fixed speeds

The controller bracket kind of fits in my floppy drive slot in the front of my computer the side tabs could have been longer

It would have been nice if silverstone had placed extra holes for future use in these brackets it would have saved the need to remove the controller and drill more holes myself
