Yah I saw that as an option also. Unfortunately I live in the US and due to reasons (tariffs) the creator of the open fan is currently not selling to US customers. So this is not an option currently for me. 

Bummer...

 

If you can get one pwm fan header to work, then split it and use this https://www.amazon.com/Thermalright-Integrated-10-Port-Controller-Support/dp/B09CH31RM6/

 

If not then maybe CORSAIR iCUE COMMANDER CORE XT

 

Neither worm as good as an OpenFan

 

Or better yet, see if you can find an OpenFan used...

Or maybe have it to delivered to a friend somewhere else, maybe Mexico or Canada, then go pick it up from there...

Or order it for hotel delivery on your next business or hotel trip.

  • Thanks for you greate step-by-step guide Works for ASUS W680-ACE

  • You need to install this and reboot afterwards:   (please keep in mind that this is not related to this thread because NCT chips are completely different).

  • It seems that it cannot load correctly due to the drivers for the Kraken not being part of the OS. Looking at others online, Kraken AIOs seems to be very sporadically supported on Linux and many optin

i dont know if this is a good place to look for help.

Hello .. been playing around with the IPMI and I can not under understand. I don't seem to be able to edit anything. the IPaddress is there and i have entered the username and password. I know the username and password it good.

I am using a SuperMicro :

Supermicro X9QR7-TF+/X9QRi-F+ , Version 123456789
American Megatrends Inc, Version 3.0a
BIOS dated: Thu 3 Apr 2014 12:00 AM

No sure will it work with my computer setup. i have looked for any fan drivers from supermicro but could not find anythihng yet, if not any thoughts.

Thanks John G.

Not really the right place, but I know Supermicro boards can be a b* because their fan control runs through the BIOS and ipmi commands.

What you could try to do is:

Run lm-sensors to see if it works

Then run fancontrol to see it works now

If it does then try to not use Dynamix but the new FanControl Plus https://forums.unraid.net/topic/191722-plugin-fancrtl-plus

If this all fails and you want actual control, you're better off with a fan controller like OpenFan.

Sorry couldn't be of

more help!

Hello,

I am having weird issues with PWM, and fan speed sensors. I expect it is related to the drivers. How to find out which driver I need to use? System temp plugin detects it87 k10temp. However I am having weird issues.

I have 3 fans connected on different mobo headers. Sys fan 1,3, CPU. Issues:

  1. Unraid only detects fan speed for sys fan 3.

  2. PWM control only works at 1000 - 1700 rpm. Fan does not slow down bellow 1000 rpm.

Mobo: Gigabyte aorus b550 v2

I expect that my issues are due to wrong drivers?

I'd like to be able to see all 3 of my fans and have my case fans spin up only when my disks are active... FanCtrl plus seems perfect for this task yet my fans do not spin down bellow 1000 rpm...

pwmconfig command returns the folowing:

Found the following devices:
   hwmon0 is acpitz
   hwmon1 is k10temp
   hwmon2 is nvme
   hwmon3 is nvme
   hwmon4 is nvme
   hwmon5 is it8792

Found the following fan sensors:
   hwmon5/fan1_input     current speed: 0 ... skipping!
   hwmon5/fan2_input     current speed: 0 ... skipping!
   hwmon5/fan3_input     current speed: 1695 RPM

Testing pwm control hwmon5/pwm3 ...
  hwmon5/fan3_input ... speed was 1695 now 1136
    It appears that fan hwmon5/fan3_input
    is controlled by pwm hwmon5/pwm3

The RPM of a fan it's driven by it's design. Not all of them go down to low or zero RPM. I am dealing with this today, got numerous that would not go below 750rpm. Without restarting the system or changing any settings,I swapped it for Noctua NF-P12 redux-1300 PWM and it manages to drop to 0 RPM. That fan spec specifically says from 0 RPM, that is why I bought it. Many other models don't go down to zero.

Typical CPU fans, especially the cheap ones bundled with CPU have about 1000RPM minimum. Also, the higher the power/max RPM, the lower the chances it will spin down to zero RPM.

I do see that you have a chip it8792 - this is what lead me to this post. I have the same chip controlling 3 of my 6 fans and I can't get it to control speed at all thru unRaid 9but they do report RPM). My other 3 are on it8688 and I have full control of them

I know the limitations of fan RPM and I know it is not the case as the same fans were plugged on different headers yielding different results. Issue was due to it8792 chip and its implementation on unraid. I just switched to a header that is on it8688 which solved all of the issues. So most likely case is that the driver has an issue with this chip.

Regarding fan speed not displaying - apparently playing around with PWM causes issues with the driver which in turn can brick systemp temps plugin from loading the proper driver to display RPM. System restart usually fixes that...

Anyway summary for PWM on unraid - pray that it works and don't touch it if it does. If it does not - 1st try server restart.
