Fan Speed Controller?

  1. Hey Guys,
    I'm currently in the progress of making a stealthy closet grow.

    However my 4" inline fan is making a LOT of noise. I have already put the fan in a fireproof, noise-insulated box. I have also switched to using insulated ducting, which definately made a huge difference.

    The only thing I could wish for was a way to control the speed of the fan.

    I have heard about hertz-regulators and so forth. But people often say that these make some sort of humming noise. And the other types of controllers are usually rated for 8" inch fans or larger.

    The last (and pretty important) thing is, that I live in Europe and therefore need the controller to be rated for 220V AC, and equipped with a EU-Plug.

    What can you recommend for my 4" inline fan?

    Cheers, Paternoster [​IMG]
