    S1200BTL system fan speed




      I have an S1200BTL motherboard in a non-Intel chassis.  The system fans appear to run at full speed all of the time and it is LOUD.  There are two system fans connected: one on SYS FAN_1 and one on SYS FAN_4.  I installed what I believe to be the latest firmware package (S1200BTL_S1200BTLRM_SUP_EFI_BIOS40_BMC1.15_FRUSDR1.16.zip), but it did not help.  The BIOS still only has an option to change the altitude (the fan speed is set to auto and is not configurable).


      Any suggestions to make these operate properly?
