I just purchased the CNPS9700 LED and the cable that comes with it is 3 pin but my M4A79XTD EVO motherboard's 'CPU Fan' is 4 pin. Questions: can I plug the 3 pin into the 4 pin missing one pin (and risk a short) or do I connect it to one of the other 3 pin fan such as the PWR FAN or the CHA-FAN2? Thanks
