i'm going to cut and rout out holes in my desk to fit 2 60mm fans so i can cool off my laptop when it's on my desk. i don't want to buy a laptop cooler tray thing because i'm cheap, and i've already got fans and broken usb peripherals to get the cable from. i know you can do it because most laptop coolers are usb powered. i need to know what part of the usb cable conducts the power to the fans. help?

The voltage of USB ports is only 5v which in some cases isn't enough to start a fan let alone run one at anywhere near full speed.

8 x 1.5v batteries to get to 12v but they'd likely not last long. Better to get a 12v transformer with enough ampage to run them.

You might try something like this. I'm sure there are other fans that run natively on 5V as well. I like the USB idea. Very convenient :thumb:

Somehow I don't like the idea of straining the usb power to it's limit. But I agree it would be very convenient.. :)
