The fans improved GPU thermals about 3-5C for me but only at full throttle so overall it didn't really help with the noise unfortunately...I've cut and soldered a custom cable to run all three fans off one PWM motherboard header, but you can also order a cheap 3 to 1 fan splitter cable. For mounting I've just used some "foam tape" between PSU and the inner case part to hold the fans in place.
