The board has 8 fan connections of which 5 are currently used, the w83793 sensors show 10 fan outputs, I plan to add 2 more fans next week as the hot swap drive bay has slots for 4 but only comes with 2, I have not disabled any of the fan sensors in the config file so every minute sensord logs alarms for the unused fans: Oct 4 16:34:06 supermicro sensord: Sensor alarm: Chip w83793-i2c-0-2f: fan9: 0

system with these modules unloaded but I wondered if this was a known issue that has already been fixed?
