Is this possible, feasible, or a total waste of time? I've been contemplating replacing the fans on my 290x to get better cooling peformance but retain the original heatsink, but I also want to keep the pc as quiet as possible but not use a bay mounted fan controller so I thought of using a pair of pwm fans spliced into the gpu circuit board header, so enabling me to use afterburner or trixx to control the fans. Is this doable or am I wasting my time?
