Hey just curious to if any one know a way i can use the macro keys on thelogitech g510 keyboard to change my gpu fan speeds on the fly would like to have 1 key to set the fans to 40% one to 60% one to 80% and one key to 100%. I do have 2 7950s in crossfire so it would need to change them both at the same time or i can have 2 buttons if binding the command to both card on one button isnt possible.
