ReadyNAS Ultra6 system temp warnings every 15 minutes

[MueRNL]

My Ultra6 keeps emailing me about system temperature alerts.. at ~25 degrees celcius. So basically room temperature. I've been messing about with the sensors configuration, but for some reason I cannot seem to get the desired results. I would appreciate any help with the sensors problem, and with fancontrol.

The system is operating on ReadyNAS OS v6.10.2.

The problem sits in the min/max temps. Here is my sensors output:

System:      1054 RPM  (min =  399 RPM)
System:       +28.0°C  (low  = +28.0°C, high = +28.0°C)  ALARM  sensor = thermal diode

Due to the low and high being set to the current temp, it's in a constant alert state.

And my /etc/sensors.d/system.conf

root@MueR-NAS:~# cat /etc/sensors.d/system.conf
chip "coretemp-isa-0000"
        label temp2 "CPU"
        compute temp2 @%35, @%35
        ignore temp3

chip "it8721-isa-*"
        ignore in0
        label in0 "V+12"
        compute in0 @*4, @/4
        set in0_min 10.8
        set in0_max 13.2
        label in1 "V5_0"
        compute in1 @*1.68, @/1.68
        set in1_min 4.7
        set in1_max 5.3
        label in2 "V3_3"
        compute in2 @*1.649, @/1.649
        set in2_min 3.135
        set in2_max 3.465
        ignore in3
        label in4 "V1_2"
        set in4_min 1
        set in4_max 1.3
        ignore in4
        label in5 "V1_8"
        set in5_min 1.5
        set in5_max 2.1
        label in6 "V-12"
        compute in6 @*19-50.4, (@+50.4)/19
        set in6_min -13.2
        set in6_max -10.8
        set in7_min 3.135
        set in7_max 3.465
        ignore fan1
        ignore fan2
        label fan3 "System"
        set fan3_min 400
        ignore temp1
        label temp2 "System"
        set temp2_min 1
        set temp2_max 80
        ignore temp3
        ignore intrusion0

I've reloaded the sensors configuration several times to no avail. Does anyone have a working RNDU6000 sensors system config that doesn't spam to death about the system temp?

On a related note, due to the constant alarm state of the system temp, fancontrol is all over the place. Spins up, then 5 seconds later spins down again. Really annoying to say the least. While I'm pretty sure that this problem might fix itself once the temperature issue is solved, if someone does have a working Ultra6 fancontrol config, I would appreciate it.

Thanks in advance for any pointers!

What is the history here?  Did it begin misbehaving when you converted to OS6, or is this new since an OS update?

[MueRNL]

Ah yes, sorry, I forgot to add that. It started misbehaving when I updated from 6.9. I do recall having had this problem with an earlier version of OS6, but can't recall how I fixed that as that was roughly when OS6 became available for the Ultra6. It's just weird that the system apparently chooses to ignore min/max temperature settings as configured.
