Easy fix fan/temp OS6 issues on x86 legacy #no support

I'm running in a similar behaviour on my Ultra 6 upgraded to 6.1.4. the fan slow down when I run /etc/init.d/fancontrol start but after few minutes I get a warning on hdds temperature:

Thu Nov 7 2013 23:34:23	Disk: Disk in channel '5' (Internal) exceeded safe temperature threshold (70 C).

and after few minutes the Nas shutdown automatically.

Any suggestion ?

Here my /etc/fancontrol file

# Configuration file generated by pwmconfig, changes will be lost
INTERVAL=10
DEVPATH=hwmon0=devices/platform/coretemp.0 hwmon1=devices/platform/it87.2576

You can try to upgrade a little bit the fan speed.
Test 45 or 50 as fan speed. Change this lines in fancontrol file:

MINSTART= hwmon1/device/pwm3=50
MINSTOP= hwmon1/device/pwm3=50
MINPWM= hwmon1/device/pwm3=50

Hi glem,

thanks for the help, I did set 50 but unfortunatly after 1 hour the hdd temperature went close to 70°C again :(

OS 6.x on it8721 chip use fan1 sensor to drive enclosure fan and temp2 sensor to monitor enclosure temperature (this configuration works fine on Ultra2 model, for example).

Unfortunately, ultra6 model use fan3 and temp1 sensors.
To activate reports and history on frontview on ultra6 model running OS 6.x, you must add this sensors.d config file to compute the correct values:

in /etc/sensors.d add this file rndu6000.conf

chip "it8721-isa-0a10"

compute fan1 0+fan3_input,0-fan3_input
compute temp2 0+temp1_input,0-temp1_input

and restart your ultra6 NAS

no luck :( had to stop fancontrol manually

Have you installed sensors.d file conf as described in this post http://www.readynas.com/forum/viewtopic.php?f=51&t=71155&start=60#p411650 ?
Are you able to see on frontview the speed of your ultra6 fan ?
Did you change the fan or is it regular fan ? fancontrol values are different for each fan.

You can see 400 or 500 rpm as fan speed in this nas log. it's not enough .... With regular fan, speed would be 850 rpm minimum to keep cold the ultra6 enclosure.

Tune your fancontrol file to have 850 rpm minimum

Hi glem,

thanks again for the help!
* yes I installed sensors.d file conf as suggested
* yes I'm able to see on frontview the speed of my ultra6 fan
* it is a regular fan

how I can tune fancontrol file to have 850 rpm minimum ? here my fancontrol file:

upgrade pwm3 values : for example try 70, and after 75, 80 ....

change these lines in /etc/fancontrol file

MINSTART=hwmon1/device/pwm3=70
MINSTOP=hwmon1/device/pwm3=70
MINPWM=hwmon1/device/pwm3=70

and then execute this command to override fancontrol daemon

/etc/init.d/fancontrol restart

look on frontview the speed fan ... and try again


You can also run pwmconfig (as described in the second post of this topic) to look at concordance between pwm3 values and fan speed

I installed OS6 on my old version ReadyNAS Pro 6350 (MB version is Flame 6 Ver 1.1) and all works fine except that in Frontview both the fans constantly show as running at 5355RPM and Temps are as follows Aux 40degC CPU 43degC and System 40DegC

Fans seem to be working normally but the speeds are not being reported properly. Not sure about the temps at the moment.

Any tips?

Cheers

Did you install 6.0.x or 6.1.x ? if you have 6.0.x, update first to 6.1.x and check reports.

If all fans and temps seem to be working fine, you have just to add a sensors.d config file to compute the real values in fan and temp input expected by frontview.

Use this example working on ultra6 model to define your own config file. http://www.readynas.com/forum/viewtopic.php?f=51&t=71155&start=60#p411650
- chip statement is the name of your chip
- compute statement : example: compute fan1 0+fan3_input,0-fan3_input
The first argument (fan1) is the feature name. The second specifies how the raw value must be translated to the real-world value (0+fan3_input); The third specifies how the real-world value should be translated back to the raw value (0-fan3_input)

Find in the folder /sys/devices/platform/it8.... or w... or i8... (depend of your chipset) the files temp(x)_input and fan(x)_input which report your box values and use compute statements to put these values in the files expected by OS6 (files are not modified, changes affect only memory).
