Weird Fan Problem on RNDP6000 with 6.4.0

Hello,

 

When I have my stock 120mm rear fan (or aftermarket) plugged in, it will spin fast at boot up, but it will not spin after that.

 

I thought the fan was bad, so I purchased a Noctua replacement, which did the same thing.  The fan spins at bootup, then once booted no more.

 

I saw a thread about a CPU fan and there is a BIn file called ToggleSwitchProFan_1.0-x86.bin, but I have not used that yet.  The fan is plugged in correctly to the stock connector.  I even tried the other unused connector on the daughtercard, that does not work either.  Either 120mm fan will spin fine when using any other power supply.

 

While I just noticed this recently, I am not sure how long it has been happening.  I did a complete factory reset when I went from 4.x to 6.4.0.  I am not sure if this existed before or after the upgrade.

Thanks for the help.

  • I fixed it, this is the post that tells you what to do:

     

    https://community.netgear.com/t5/ReadyNAS-Beta-Release/Fan-CPU-Enclosure-Errors-on-Pro-after-upgrading-to-6-4/m-p/990914#M6842

     

    Add the following line to the system.conf file (I added to the end of the file& beginning) in the /etc/sensors.d folder:

     

    ignore fan3

     

    I actualled added both ignore 2 & 3, not sure which did the trick.  There is also a file called pro6-fan.conf, so I added there as well.

     

    Here is my entire system.conf file:

     

    root@RNDP6000:/etc/sensors.d# more system.conf
    chip "coretemp-isa-0000"
    label temp2 "CPU"
    ignore temp3
    ignore fan3

    chip "w83627dhg-isa-*"
    label in1 "DDB18"
    set in1_min 1.62
    set in1_max 1.98
    label in2 "AVCC"
    set in2_min 3.3 * 0.90
    set in2_max 3.3 * 1.10
    label in3 VCC3
    set in3_min 3.3 * 0.90
    set in3_max 3.3 * 1.10
    label in4 VCC1_25
    set in4_min 1.17
    set in4_max 1.32
    label in5 "VCC1_5"
    set in5_min 1.41
    set in5_max 1.58
    label in6 "VCC1_05"
    set in6_min 0.98
    set in6_max 1.10
    set in7_min 3.3 * 0.90
    set in7_max 3.3 * 1.10
    set in8_min 3.0 * 0.90
    set in8_max 3.3 * 1.10
    label fan1 "System"
    set fan1_min 600
    label fan2 "CPU"
    set fan2_min 150
    label fan3 "System"
    set fan3_min 600
    ignore fan4
    ignore fan5
    label temp1 "System"
    set temp1_max 80
    ignore temp2
    ignore temp3
    ignore cpu0_vid
    ignore intrusion0
    ignore fan3

     

    I hope this helps someone else.
