I just updated my firmware to 2.19 on my CRS310-8G+2S+ and the fan has ramped up dramatically.
Finally got it to stable level with...
Fan Target Temp (C) = 60
Fan Control Interval (s) = 30
Current temps:
CPU Temperature 41C
Board Temperature 1 32C
PHY Temperature 52C
FAN1 6780 RPM
Are there any recommendations/guidance on the best settings for this model and firmware?
It used to be a little loud, but this is considerably worse than it used to be!
