Hello everyone. I have a can fan 5inch being used for intake and have been using an sms dimmer switch type controller. The problem is with the hum on low speeds , I was about to order a variac controller when my freind gave me this flaktwoods controller me 1.3, 1ph 3 amps max output. My question is , is this ok to use with my 5inch can fan and does it work the same as a variac eliminating hum??
