  • Did this add the variable speed fan control as well or was fan speed slightly reduced?  I just performed the update.  It seems the switch dropped 1 or 2 db but I see nothing in the UI to indicate this.  Currently I am only using 2 POE ports, drawing under 10w total and it runs cool even with the lower fan speed.

    Hi @GadgetryTech
    The release includes the smart fan design as the variable speed fan control you mentioned. The system will start up at the lowest fan speed, and during operation, fan speed will be adjusted linearly based on system temperature.
    So basically this is determined by the device itself.

    BTW, the NebulaFlex switches are less noisy by hardware nature since the maximum fan speed has lower rpm.

    Cheers :) 
  • Thank you.  I heard the fan drop a little in speed when it rebooted after the update.  At least I know I'm not crazy.  Are the plans to for more insight on hardware such as sensor thermals and fan speed (rpm).  The switch is currently drawing less than 10w so I wonder if the fan speed could be dialed back even more.  Thanks!

    Hi @GadgetryTech,

    Thanks for your advice, I will post a new topic in Idea section for "Current temperature and Fan speed of Switch can be shown on Nebula CC".
    Please note that the smart fan feature only supports on NSW200 series and Hybrid Switch due to hardware limitation. Also the fan speed depends on the temperature of Switch, not how many PoE power Switch send.

    Hope it helps.
