Why not just use and extra 12V plug from your computers power supply? Computers usually have a few extra 12V plugs.

If the system can actually provide the current to BOTH the usb ports and if you get a device that can make use of both (don't want to just connect the two together) and also convert the voltage, then in theory it might work, but you are going to be draining power from the laptop. The cost to properly do all of this is going to exceed other better means to run the fans.
Instead, I would suggest getting a 12v battery or adapter to run the fan and not try to extract power from the USB port.
