For all three values of bios_disable_method, I get the error: g128·0 gƒ(2) set_fan_state smm_send error

I see there are some extended diagnostics in smm_send commented out in the code. I uncommented them and ran it again, in case that's useful.

I wonder if the problem is that my bios is too old. dmidecode reports:

BIOS Information
        Vendor: Dell Inc.
        Version: A15
        Release Date: 05/19/2015

Hi! Seems problem in detection gpu (sensor & fan)
Could you provide next information:

  • output of sensors -u (dell_smm-virtual-0 section)
  • device model (i'm interesting: is it has discrete gpu and real number of fans?)

Thanks. It's a Dell Latitude E6540 (Version 01, according to dmidecode) made mid-2015.

Problem is that yours device has 1 fan, and current code expect 2 fans.
I need some time to make workaround about fans detection.
I'll let you know when finish.

Okay, thanks! Let me know if I can help.

Okay, please check last master - i think it will works for you.
Could you please provide me your auto-detection lines (sudo ./dell-fan-mon -t -v):

Sensors autodetect: t0·0·cpu·44° t1·1·gpu·44° t2·2·53° t3·-1
Fans autodetect: ƒ0·0·cpu ƒ1·0·cpu ƒ2·-1 fans_count = 2

It works! Thank you! For me, a t_low of 50 will mean the fan is almost never on. Very nice.

Interesting that the low fan speed is a lower fan speed (2500 RPM) than the BIOS lowest fan speed (3200 RPM). Seems fine. Two CPU threads stays about 60C.

I don't see a "Fans autodetect" line there. Here's the full output:

$ sudo ./dell-fan-mon -t -v
/etc/dell-fan-mon.conf line 49: parameter monitor_fan_id is deprecated(ignoring). Please remove this line.
/etc/dell-fan-mon.conf line 75: parameter cpu_fan_id is deprecated(ignoring). Please remove this line.
Sensors autodetect: t0·0·cpu·51° t1·4·54° t2·2·33° t3·1·128°
If you don't have discrete GPU - you can ignore this message.

Couldn't autodetect gpu_temp_sensor_id. Seems there no discrete gpu.
Using discrete_gpu_mode 0 (cpu temp monitor only)

PLEASE NOTICE: If you have discrete gpu and can get temp via command line utilites
You can set get_gpu_temp_cmd in /etc/dell-fan-mon.conf to provide command for acquiring gpu temp
As output of command dell-fan-mon awaiting line with number.

Oh, one little thing, when I start it, and we're already below t-low, with the fan on because the BIOS had it on, the fan stays on. Once t goes up and comes back down below t-low, the fan shuts off.

Please check last master: i'm fix startup issue.
Also please edit /etc/dell-fan-mon.conf and set discrete_gpu_mode 0 - to avoid message about GPU. Also remove lines with monitor_fan_id and cpu_fan_id.
After that please send me output of sudo ./dell-fan-mon -t -v.

@sandhawke

$ sudo ./dell-fan-mon -t -v
Fans autodetect: ƒ0·0·cpu ƒ1·-1 fans_count = 1
Sensors autodetect: t0·0·cpu·55° t1·4·57° t2·2·38° t3·1·128°

And startup seems to work now, shutting down the fan immediately, when the system is cool.

Thank you again!
