Lenovo y50-70 "There are no pwm-capable sensor modules installed "

yusufmoh · 2017-02-27 10:15:14

Hello Every one,

I have been using Arch linux on my Lenovo Y50-70 (exact model number : 20378) for a while now, and everything seems to be working great actually, one problem is annoying me though, the fans keep running at high speed all the time, and the sound is really annoying sometimes, although the cpu temperature appears to be fine (between 45 - 55 ℃), when I try to enable fan control using the procedure in the wiki page, I get stuck at the pwmconfig step.

sudo sensors-detect --auto output:

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

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      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): 
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): 
Using driver `i2c-i801' for device 0000:00:1f.3: Intel Lynx Point (PCH)
Module i2c-dev loaded successfully.

Now follows a summary of the probes I have just done.

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

Do you want to overwrite /etc/conf.d/lm_sensors? (YES/no): 
Unloading i2c-dev... OK
Unloading cpuid... OK

I have checked the official lm-sensors devices list (https://hwmon.wiki.kernel.org/device_support_status) but I am not sure about the chip name for my laptop.

any help will be much appreciated

Hi, have you been able to solve this issue? I'm having the exact same problem, it's quite annoying sometimes.

Or, is there anyone else who could help?

Unfortunately I was not able to solve this issue.

I only improved ventilation beneath my laptop by keeping it elevated from the table
