I bought a little pc fan and tried to connect it to a 9 volt battery and it wouldnt work. The wires are very small and im not sure how to connect it to power?
you have to strip both wires about half an inch or smaller, enough to twist up to ur 9v n wrap it with electrical tape. there are some tutorials on youtube to get a better idea. i didnt see 3 wires on ur pc fan, but for future reference you only need to strip red and black
