I recently purchaced a XFX Pro650W Powersupply unit, with a 5 yaer warrenty but it's making a rattling clicking noise on the fan. I know this isn't normal but the shipping factory is in Japan and I am in Britain, so it's not the most accesable return policy in the world. What should I do, return it and wait (a long time), phone them first(they might not speak english), see if there is another factory in a closer location(how?), or just try to fix it myself?
