I have a launch wii and modded it last year. Lately after playing a game for more then an hour it will randomly just shut off and the led will go out. To get it to turn on again i have to unplug it and plug it back in. I think the fan might of failed on it and i was wondering if there is any way to test it. Also would a usb fan be enough to cool it or if not is there anywhere that i can get a replacement fan?
