Hey guys we want add a second fan to my friends Corsair H60 (old one). We don't have the screws and we can't buy the additional screw kit that corsair sells since they are not available in our crappy country. So can we get our screws from a normal hardware store that sells paint, screws etc? If we can what kind of screws should we buy? I think M3x30MM screws would be enough for radiator but we are afraid of the possibility that we might damage the rad. And also, we have a spare fan for the case but we can't find the screws for it. What kind of screws do we need for the case fan also?
