pwm not detected

[svenvg93]

I'm trying to setup Fan Auto Control.  But can't seem to detect the pwm controller and fans. 

Using the Gigabyte H370 HD3-CF motherboard which should have pwm.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): yes
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): yes
Found unknown SMBus adapter 8086:a323 at 0000:00:1f.4.

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

Do you want to generate /etc/sysconfig/lm_sensors? (yes/NO): no
To load everything that is needed, add this to one of the system
initialization scripts (e.g. /etc/rc.d/rc.local):

#----cut here----
# Chip drivers
modprobe coretemp
/usr/bin/sensors -s
#----cut here----

You really should try these commands right now to make sure everything
is working properly. Monitoring programs won't work until the needed
modules are loaded.

Unloading i2c-dev... OK

 

root@unRAID:~# pwmconfig 
# pwmconfig revision $Revision$ ($Date$)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

 

How can I get pwm working so I can control my fans within unRAID.

[ibasaw]

i got same problem here

[desinox]

same problem here

[jayephx]

Is there a solution to this problem? I am running into same thing, cannot detect PWM.

[Bender Seb]

same problem here

[Wicked_Chicken]

LIkewise. Fans set to PWM mode in BIOS but still can't be found. 

[MRBONDY]

Not a super advanced user so take all of this at your own risk

I also have a Gigabyte board - gigabyte z270mx gaming

 

So using sensors-detect this is the only module detected other than coretemp

ITE IT8686E Super IO Sensors
(address 0xa40, driver 'to-be-written')

 

I used this command to force load the it87 driver under a different an ID which it recognised which works correctly with the IT8686 chipset (for me)

modprobe it87 force_id=0x8628

This got my PWM fans working and detected by Unraid

I was then able to see the fans in Dynamix System Temp and enable the fans so that Unraid can see them and display them on the dashboard

You then need to put that last command into your go file so it gets loaded at boot

I used 'Config Editor' by Squid to edit this easily

 

Using pwmconfig or pwmcontrol in the console just ended up messing with things and I had to reboot to get it all fixed

 

Dynamix Fan Auto Control was then able to see the chipset and PWM fans

It could see the fans in this fan control fine before my reboot but it wasn't able to control any of my fan speeds

After the reboot Fan Auto Control was able to correctly detect my 4 fans and detect the minimum PWM value (min PWM detect was a particular issue before reboot)

I was still having trouble before I realised that you have to enable the fan control function individually for each of the PWM fans

 

Finally success, I have conquered this Gigabyte board!

 

You may need to add this line below to syslinux.cfg to get this to work on some boards

acpi_enforce_resources=lax

 

 

Here are some links to key resources that helped me:

In reality all of this is just saying that Squid's advice just below works for Gigabyte boards

i have similar issues. i installed unraid on a mini pc based on Intel H270 board as far as i know. sensors-detect found this:

 

Do you want to scan for Super I/O sensors? (YES/no): yes
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               Yes
Found unknown chip with ID 0x1e11

sadly motherboard temperature and fan are not detected. what kind of workaround should i do?
