    Well, it’ll work, but really not as well as fan could do, the fan normally taking 12v and the USB connection only supplying 5v. I think firewire has a 12v line in it, but of course firewire is much rarer.

    Besides the fact that it’s 5v instead of 12, since that’s what the fan wants. A fan like that needs 1A, and usb can only provide 500mA(if negotiated, if not then 100mA); so by using this you’ll probably burn a mobo

    Hey, I have some terrible noises coming from my laptop fan, especially when it s getting hot, I believe that the heat provoke the noises, they suggested me to open it and clean it inside, I did, the noise became less violent and not current like before, but it’s still there from time to time I hear it,

    Should I change the fan of my laptop by a new one (may be the engine inside the fan is getting tired ?) here is a picture of my fan : when I opened it there were a lot of dust.
