lxtwin Posted January 25, 2013 Share Posted January 25, 2013 I have just connected the two fans to my cooler and noticed that the button /switch on the H80 that changes the speed has no affect on changing the speed. Is this normal ? If so I think I will have to return them as the fans at full speed all the time are a little noisy. Link to comment Share on other sites More sharing options...
