I have had the Aerocool F6XT fan controller for around a year now and when i put the fans on the minimum setting it makes this noise from the fans that are really annoying. i have recently bought some speed reduction cables but it is still making the noise. The fans that I have are the coolmaster sickleflow 120mm fans.
does anyone know how to fix this problem?
i have tried the exact voltages when plugging the fans into the motherboard and it does not make the noise
Hmm, that's very weird. In that case, it might be the fan controller. Don't quite see how that's possible though. A fan controller should should feed a voltage to the fan, higher volts = higher speed. I don't understand how it could cause a fan to vibrate. Have you made sure none of the wires are getting stuck in the fans?
