I recently build a new PC with a corsair H80 and a sabertooth Z77 motherboard but when i boot up my pc the fans dont work unless i plug in the molex conection but it still says cpu fan error on boot anybody know what to do?
email the cooler tech support people and ask asus what pin on there fan header in the pin used to know that a fan is connected.
the other three pins two are used for power and the last is pmv to speed a fan up or down. the asus mb the fan header on the outside of the mb and there two of them. cpu main and cpu backup. you need to connect it to the right header and not miss any pins.
