      Hi All,

       

      I have a problem...Ive had this board for a couple years now and its worked perfectly on the lastest bios.  Recently I installed a 3 pin fan to the rear and aux fan header on the motherboard and the cpu wont turn on and its giving me the 3 beep and error code 20.  I took out the 2 fans from the header and everything is back to normal.  I looked in the bios and the fans are set to Auto for both headers.

       

      Can this board work with 3 pin fans? if so how? what do I have to change in the bios to get this to work?

       

      Thanks
