how can you make a inverter that input 5v dc and output is 12v dc?

I'm making a usb fan but it need more voltage to the fan 12v im only getting about half from the usb.

Fist choice would be to get a 5V motor.

Second choice would be to buy or construct a dc to dc converter.  Google that and see if you come up with anything that looks useful.

Remember that the usb port will only supply 1/2 amp safely.

invert thatto ac, transform it (5:15), bridge the transformer, (full wave diode rectifiyer) 12v almost dc. done.

Have you got a spare MOLEX connector inside the case? It'd be much easier.
