CPU Fan stuck on 4218 rpm

Hi,

 

The CPU of my Pro RNDP6000 is stuck on 4218 rpm. The box is on 6.9.0. The cpu temp is 47. The  fan starts off slow at around1500rpm and works its way up 4218 rpm after about 10 minutes and stays there, all day. It's always 4218rpm. I've tried it with the side off, still does it.

The system temp is 45 with 852 rpm, the 6 disks are between 38-40.

 

It's been like this for a few months. I've tried the three setting, still does it.

 

Any idea whats going on?

  • Sorry for you to hear this, but happy you are sharing this.

    I'm still running my PRO 6 on 6.5.0 (my best fan behaviour experience since I bought it 5 years ago) and will avoid 6.9.0. based on your message.

     

    Needless to say that I hope for you that your problem gets fixed.

      Hi,

       

      Nothing to do with 6.9.0 because as stated it's been like this for months.

        Do you know if your CPU fan is of the three-pin variety connected to the I/O board or 4-pin variety connected to the motherboard?  Another user reported a similar problem and he got it fixed by making changes in the system.conf file, though he had just changed from 4.3.x to 6.x.  Did it happen at some OS update?  Somewhere along the line in 6.x, Netgear may have left out the configuration for the 3-pin fan in the 6-bay Pro models.  I frankly have no idea how it could tell which it is, so maybe that process just fails sometimes during an update.
