    The jumper would allow you to switch between running at 5v or 12v, if I understand the diagram right. :)

    These Rosewills are pretty spiffy; http://www.newegg.com/Product/Product.aspx?Item=N82E16835200028 That is when they're in stock, and you tag them onto another order, due to the shipping cost for one. Although, the controllers do eat up PCI expansion slots. The controllers are active amplifiers, not just variable resistors. You can get 80mm too.

    Oh, and blue LEDs also, that dim when the fans are turned. I'm not a case mod freak, but a blue fan glow through the front grille is kinda soothing.

    I ran the Homemade fan controller on an old pc for testing overnight and everything works. I hope this is ok to use long term

    I might try doing this myself, even though I only have one fan...
