I recently upgraded to this motherboard Supermicro | Products | Motherboards | Xeon® Boards | X9DR3-F from this Supermicro | Products | Motherboards | Xeon® Boards | X10SL7-F the issue i'm having is that the fans will speed up all of the sudden then they will slow down. It does it non stop no matter if i set the ipmi fan speed to Optimal. The work around i came across was setting the bios under cpu performance to energy efficient. I did change it back to performance after the fans would stay at optimal speed which i thought was weird. But after a reboot they went back up to spinning up fast then slow , and once again i had to change the cpu performance to energy saver. Is there a reason why this is happening and is there a solution to be able to run the cpu's on performance mode without running into this problem?
