Easy fix fan/temp OS6 issues on x86 legacy #no support
>> EDIT - 2014-04-12 <<
Before to hack your system, update first to 6.1.7. Built-in fancontrol support is there!
6.1.7 has been released: http://www.readynas.com/forum/viewtopic.php?f=1&t=76000
>> EDIT <<
Here is how to fix fan and temperature issues on legacy x86 systems running OS 6.x, until built-in support is there.
I'd previously created this post http://www.readynas.com/forum/viewtopic.php?f=51&t=70133&start=255#p393886 but it will be easier for community to have fancontrol file examples for all models in a dedicated post.
It's a very easy and reliable method to monitor fan and temperature with lm-sensors and fancontrol standard packages.
No change on GUI reports.
NO WARRANTY / NO SUPPORT !!!
with root access, execute the following commands:
edit /etc/fancontrol file and copy the following file example corresponding to your model http://www.readynas.com/forum/viewtopic.php?f=51&t=71155#p395324
or create your own /etc/fancontrol file using pwmconfig command http://www.readynas.com/forum/viewtopic.php?f=51&t=71155&p=395324#p395318
fancontrol daemon start automaticaly when you install it.
restart fancontrol daemon for changes in file /etc/fancontrol take effect
to interact with fancontrol daemon, use
You can display sensors values with sensors command

- Do you still get the fan warnings now that it goes down to 900 rpm? It may be that a reboot is needed after the firmware update for the new minimum fan speed of 900 rpm to take effect.
- I got bad news. I installed the OS6.1.9 RC8 yesterday, it seemed to be working fine and I stopped getting the fan warnings and the fan ran at ~850 RPM.
But today I got a FAN warning (0 RPM) and temperature was at 65 C. The fan started again, but I did a reboot to get it to run at 2000 RPM to cool the system down. It slowly goes down to ~900 RPM.
@Skywalker : Is there a settings-file I can modify to get this to run at ~1300 RPM as it did in version 4.2.26?
My stats used to be HDD 35-40C, SYS 40-45C, CPU 25-30C in 4.2.26 (SYSFAN at ~1350 RPM, CPU at ~2100 RPM)
Now I'm at HDD 41C, SYS 60C, CPU 45C (only showing (SYS)FAN, FAN ~900 RPM) - I installed 6.1.9-RC-8 testerday afternoon around 15:00 and since then no longer have fan errors. My ReadyNAS Pro does still seem to run quite warm but that can also be due to the high temprature
- 6.1.9-RC8 may help with this. It will keep a memory of the last setting where the fan dropped below the minimum, and avoid going that low again.

I would love to update my Pro 6 to OS 6.1.8 but have only one concern. Has the fan issue been resolved and will it impact the longevity of the Pro 6 or is it simply a matter of disabling the email alert? Any concerns or new files to download and use? The forum thread has been mostly inactive. Will 6.1.9 or future versions address this issue such as a calibration button like on 4.2.26
Thanks. Any help would be appreciated.
Bigbearf - I've also just updated a Pro 6 for the first time from 4.2.26 to 6.1.8. I'm also getting the warning
Fan 'Fan' in enclosure 'Internal' speed is below threshold. (482 rpm)
The SYS, Disk and CPU temperature goes up and the fan speeds up, but the values are higher than on 4.2.26.
Do anyone have a suggestion on how to set a minimum speed on the fan? Is there a config file for the builtin fancontrol on 6.1.8? - I also just updated a Pro6 for the first time from 4.2.x to 6.1.8 and have the fan problem. Note that this is not a false report, my fan is really going to zero RPM! There must be something wrong in the database that lets it go that low. The system temperature does start to rise, as expected without the fan running, and then the fan kicks back on. It appears that there is hysteresis built in to the speed control, which is good to prevent "motorboating". but maybe that's also a contributor to the problem. It looks very much like the fan is not capable of running at the slowest speed in the database, and so stops. But it isn't immediately cranked back up until it overcomes the programmed hysteresis. Or maybe it's a genuine physical hysteresis - the speed to which it is set after it stops isn't high enough to get it started, but is enough to keep it moving once started.
- On my Pro 6 I have CPU 19.5 and SYS 51°C with 17.5°C ambient. Anybody knows where the "SYS" sensor is?
- Anyone concerned or having issues with the lower fan speeds? My temps on 4.2.26 are SYS 40c and CPU 29c. Any thoughts on long term effects?
Thanks
Bigbearf - After some time after the first reboot, the system temperature now stabilizes at 62 deg. and the fan at about 800 rpm. CPU temperature being still at 39 deg. Maybe the reboot did help
