          | I updated the BIOS for my rig tonight. Now the fan is running extremely fast. Upon review temps are at 67C and speeds Wraith Prism speeds are 2880 rpm. Is there anyone else having issues or could relay some help? |

          | First you have to choose the profile of the cooler on the side. There is a little switch L|H where in a nutshell max RPM 2700|3600
 
 Then in bios you have to chosse what the fan should monitor: mobo (almost steady, so useless) or tCtrl that is 10°C more of tDie.
 Set the mode to Auto (PWM speeds at max RPM the fan, useless) and chose one of the preset (silence, performance, ...) or customize the fan curve to follow your likes.
 
 You can profile also the fans with fan-tastic
