    Still a nice write up to reference for future use. I'm sure I will give it a go someday...
    I have a stash of fans I bought from newegg a while ago which i'm planning on putting on the wire shelf. I have to figure out how to fix them so that can be easily adjustable, some sort of a swiveling clamp or something . I'll post pics when I'm done.

    I also use switchable voltage power adapters, as above. Some of them are not voltage regulated though and are designed to deliver the specified voltage at the near the maximum current output; therefore, at lower currents such as those required by a fan, the voltage can actually be higher that that selected. Basically with these it is best not to run a 12V fan with the adapter set to 12V output, as it's likely to over-voltage the fan.

    What do you do when you have a four-pin fan? I have a MacBook Pro, and the fans just got replaced on it, but they're still good (just noisy) and I want to wire them up for my terrarium. A link to a picture from Amazon is below. I've wired case fans before, but all these wires are identical and I dont know which to hook up. I'm fairly hesitant to do trial-and-error, out of fear of electrocution or shorting a circuit or something.

    Thank you for any input!
