    So, I have a Lap, but ultimately, is getting a bit hot. Not to the point that it burns or it slows down the performance, but I won't wait 'till that happens... So I went to the Flea Market and bought a cheap CPU Fan.
    So, I joined its Red/Black cables with a USB that I had laying around. And it works.

    But, the Fan is much slower that I expected. I'm guessing that it must be because the voltage difference.
    Either way, I wan't to ask you guys if you know a way to make CPU Fans faster.
    FYI
    - It's not a thermal fan.
    - I don't know the brand nor the voltage. It came withouth a Label.
    - I'm using a 2.0USB in a 2.0USB entrance. I tried one 3.0USB entrance, but the speed remains the same.

    USB is 5v, so your fan will run at about 40% speed because it expects 12v. You cant do anything about that unless you hook it up to a 12v mains adapter.

    Yes, that's what I was thinking...
    So... is there any (...any...) way to remove a resistor or something to make it faster?

    Nope, that's part of the USB spec, it is always 5v. And before you consider it, joining 2 together will fry your USB ports :ha:

    Haha... I can imagine that. That's the perfect picture of me.
    I guess I'll have to stick with it until I can buy a Laptop fan...thing...

    Didn't they make a Fan header splitter (Y cable)? You could connect two fans on that one 12v line, however that might be pushing it.
