    This is for regular AC powered fans, not computer fans.

    Anyone know how to do this? I saw a video a long time ago about soldering on some capacitors or resistors, etc. I have some industrial fans that I need to speed control to be more quiet which they do wonderfully but I need to remove the hum noise in the motor that most fans seem to make when doing this.

    Would greatly appreciate any info, thanks.

    Somehow found my way onto Variable output Transformers. Think I may be onto something.

    This does the trick! Fantastic, smooth as ice sounding fans ahh I love it. To think all those crap speed controllers on the market make people think that's the proper way to do it.
