    I'm trying to hook up these 2 bilge fans in parallel to this speed controller. They will be powered by a car battery. I don't know a lot about electronics, is it possible that I will run too much power to the fans if I turn the fans to the max possible speed? How do I hook this up safely? Thanks. Links to the products i'm using above.

    Welcome to EP.

    Should be o.k
    The controller is PWM and can supply up to 10A
    The fans are 2.5A each .
    You can also fuse each fan(separately !) with a 5A fuse .

    BTW,
    In this kind of parallel operation the fans will work at about the same speed.
    If separate control is required ,you should use a separate controller for each fan.
