[lm-sensors] Asus H87-PRO /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

[Michael Vorburger]

Hello,

On an Asus H87-PRO, running on Ubuntu 13.10, if, I'm getting
"/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed"
from "pwmconfig" [revision 5857 (2010-08-22]. I've tried
the acpi_enforce_resources=lax thing, which doesn't seem to help.
http://pastebin.com/Up6KFRyu has full log from sensors-detect.

Do I need any special drivers or other settings, for this motherboard? -
Thank you for any tips!

PS: Same also on
http://askubuntu.com/questions/408929/asus-h87-pro-usr-sbin-pwmconfig-there-are-no-pwm-capable-sensor-modules-instal

Same mainboard here :-) Debian 7.3. My logfile looked almost the same.
The chip on the mainboard is a NCT5538D. You have to get the module
nct6775 from: https://github.com/groeck/nct6775

Build, install it and load the module. Run sensors to ensure that
values are shown now. dmesg should something like:
nct6775: Found NCT6791D or compatible chip at 0x2e:0x290

I had some issues with pwmconfig. The script tries to stop the fans
completely. This does not work for the cpu fan (pwm2). I had to assign
the pwm output pwm2 by hand to the inputs fan2_input.

This is my !! preliminary !! config for the mainboard:

Hi Mathias,

you were faster than me ;-). Michael, let me know if you have any problems with
the driver.

Note that the upstream driver supports the chip starting with kernel version 3.12.

Interesting that pwmconfig doesn't recognize this. CPU fans usually never stop
completely, and afaik the script should recognize the speed change.

Anyway, I would recommend to use the chip's automatic fan control if possible.
It doesn't rely on a script running in the OS to control fan speeds, and
usually works pretty well (and can be reconfigured if you dislike the BIOS
settings).

Thanks,
Guenter

During this few seconds test, /sys/class/hwmon/hwmon1/device/pwm2 is
set to 0. But if you set this pwm2 to 0, the CPU fan runs with full
speed (same rpm as with pwm2=255)
The other pwm output with a fan connected (pwm4) does not behave like
this and stops the fan with pwm0.

Normally, yes. But it was not possible to go that low with the fan
speed within the BIOS settings (20% or 25% is the minimum IIRC)
But with my current setup (i3-4130T, 35W TDP) the CPU temperature is
the last problem. I can go down till pwm 7, the fan (A.C. Freezer 13)
still runs silent and stable at ~550rpm.

@Michael: Could you give me some feedback to my mainboard config file?
Could you especially take a look at the +5V and +12V readings,
compared to the reading in the BIOS. Its possible that they are
inverted. But with my readings from the PSU I had idea how to verify
the assignment because the raw values were almost the same..
The scaling should be ok. Thanks alot!

Interesting. Obviously that doesn't help ;-). What is returned back
if you read pwm2 after setting it to 0 ?

You might try setting pwm2_auto_point1_pwm to your preferred minimum
(assuming pwm2_enable is set to 5). If that doesn't help, please send me the
output of all pwm2 attributes ('grep . /sys/class/hwmon/hwmon1/device/pwm2*').

Side note: If you run 3.13 or later kernels, the attributes will move to
/sys/class/hwmon/hwmonX/.

Thanks,
Guenter

0 (zero). Maybe some sort of protection?

Thanks for this hint. I didn't knew about this possibility.

For my needs I set these values:
pwm2_auto_point1_pwm	7
pwm2_auto_point1_temp	30000
pwm2_auto_point2_pwm	178 (default)
pwm2_auto_point2_temp	55000
pwm2_auto_point3_pwm	255 (default)
pwm2_auto_point3_temp	75000 (default)

With these settings the CPU fan (fan2) runs quiet as wished :-)

No idea. Might be the fan itself doing it. What happens if you set it to 1 ?

Excellent. Note there is one problem in the driver - any changed pwm
settings will revert to the default after a suspend/resume cycle.
That requires a major change to the driver to fix, so it will take a while.
Until then, you'll have to re-apply the changed configuration after
suspend/resume.

Thanks,
Guenter

Unlikely. The same fan model is installed on my other main-board
(Gigabyte with it8728) and its possible there to bring down the fan to
0 rpm with pwm set to 0.

> What happens if you set it to 1 ?
Set to [0-4] => fan spins up to maximum rpm (~2250rpm)
Set to > 5 => fan spins at desired rpm (~600rpm upward)

No problem for me. This box runs all the time with no suspend mode
anyway :-)

Mathias,

Can you send me the output of "grep . pwm2*" ? I'll see if I can
find anything in the datasheet that might explain this behavior.

Thanks,
Guenter

Sure. Here is the output:
pwm2:27

pwm2_auto_point1_temp:30000
pwm2_auto_point2_pwm:178
pwm2_auto_point2_temp:55000
pwm2_auto_point3_pwm:255
pwm2_auto_point3_temp:75000
pwm2_auto_point4_pwm:255
pwm2_auto_point4_temp:75000
pwm2_auto_point5_pwm:255
pwm2_auto_point5_temp:75000
pwm2_crit_temp_tolerance:2000
pwm2_enable:5
pwm2_floor:1
pwm2_mode:1
pwm2_start:1
pwm2_step_down_time:100
pwm2_step_up_time:100
pwm2_stop_time:6000
pwm2_target_temp:50000
pwm2_temp_sel:7
pwm2_temp_tolerance:0
pwm2_weight_duty_base:0
pwm2_weight_duty_step:0
pwm2_weight_temp_sel:1
pwm2_weight_temp_step:0
pwm2_weight_temp_step_base:0
pwm2_weight_temp_step_tol:0

BIOS profile set to "Quiet", values modified like mentioned in my previous
post.

Maybe Michael (with the same Mainboard) could try to reproduce this effect
on his hardware?

Thanks!

Might be a good idea. For my part I have no idea why that happens. I don't find
anything in the chip datasheet, nor in the code, nor in your configuration,
that would explain this behavior :-(.

One interesting experiment might be to check what happens if you set
pwm2_auto_point1_pwm to a value between 1 and 4. If that results in the fan
running at full speed, we have some indication that either the fan or the
board hardware is causing this behavior.

Thanks,
Guenter

Same result. If the calculated pwm value (pwm2) is smaller than 5, the
fan spins up to maximum rpm.

Today I disassembled my other pc (on which I'm able to completely stop
the fan by reducing the pwm value) with the same model of CPU fan
(Arctic Freezer 13) and hooked it up to the ASUS H87-PRO. The fan
looks a little bit different than the other, but the values are almost
the same.

Arctic Cooling Freezer 13 (Old Model)
- -------------------------------------

pwm2	rpm
1	2064
2	2064
3	2064
4	2064
5	393
6	272
7	398
8	187
9	196
10	423
11	493
20	486
30	630
40	730
50	912
60	1060
70	633
90	859
128	1251
255	2261

Almost the same result with the original fan

Arctic Cooling Freezer 13 (New Model)
- -------------------------------------

pwm2	rpm
1	2257
2	2253
3	2261
4	2180
5	551
6	451
7	407
8	370
9	366
10	370
11	392
12	411
13	433
60	1203
70	1355
90	1580
128	1836
255	2260

Then I took the boxed Intel fan and hooked it to the ASUS Board.

Intel Boxed Cooler
- ------------------

pwm2	rpm
1	976
2	974
3	972
4	976
5	978
6	972
7	975
8	973
9	973
58	976
59	1005
60	1018
61	1021
70	1072
90	1184
128	1393
255	1953

And now the interesting part ;-) Connected the original fan to
CHA_FAN2 (controlled by pwm3)

Arctic Cooling Freezer 13 (New Model)
- -------------------------------------

pwm3	rpm
1	0
2	0
3	0
4	0
5	0
6	0
50	0
55	430
60	512
70	633
90	859
128	1251
255	2261

On this pwm3 output I'm able to let the fan spin down until it stops
(around pwm 50-55)

So it seems that the CPU fan output is somehow special - but I guess
only ASUS knows how exactly and why.
