    Oh ok. I didn't know if it would stop working eventually or something.

    However, the PC fans are electrically isolated due to the fact they are not line voltage... so there is a definite safety advantage to their use,

    so if you do use the walmart fan, IMHO I would use ground fault protection (which your lights should be using anyways) and run a ground bonding wire between the steel fan and the plant rack

    Always make sure everything is grounded properly, electricity will take the path of least resistance... be it a ground wire or you

    Maxx,

    simply put, it is electrically connecting all metal components with wire, so any leakage will be given a low resistance path to dissapate...

    its easier then it sounds

    have a look at a few threads on the subject:
    http://terraforums.com/forums/showth...ight=grounding

    http://terraforums.com/forums/showth...ight=grounding

    http://terraforums.com/forums/showth...ight=grounding

    if you want more, just search for "grounding"

    chances are good you will never have an issue, but anytime you mix electicity, water and your butt... well a couple minutes of time, a gfci and a few sections of wire is a small price to pay to possibly save your life

    but that is just my opinion, I dont want to tell you what to do or how to do it

    always consult a licensed electician

    Fan

    I have a several in my set ups... just get a PC fan (3-4") ... get a small adapter (usually you might have one sitting around from some old small electronic device (An old Cell phone adapter for example).

    Splice the wires together. Wrap them individually well with electric tape. Plug it in. If it doesn't work, swap positions of the wires. Wrap. Plug in.

    Now I am not electrician.. so don't do this if you aren't one either.

    The end.

    ok I got a little 5in fan from radioshack. It's got 32cfm so it's pretty powerfull. Problem is that it isnt reducing the temp by more than a few degrees. What could I doing wrong? Is there a certain way to position the fan?
