[SOLVED] Thinkpad T61p fan

How do I know if my fan is working like it should? I have cpu scaling, and "acpi -t" gives

Battery 1: charged, 100%
     Thermal 1: ok, 48.0 degrees C
     Thermal 2: ok, 45.0 degrees C

the temperatures look ok, but I'm not really doing much, and it's quite a cold weather today.

Following the thinkwiki, I entered

modprobe thinkpad-acpi experimental=1 fan_control=1

, but what's the daemon or module for this to so that the fan starts up on bootup? does this modprobe thing last permanently or just for this session?

Hello

I believe in the rc.conf file, there is a "MODULES=" field (sorry I'm at work so I can't check) and just enter the module you want to start up automatically.

Correct me if I'm wrong

Re: [SOLVED] Thinkpad T61p fan

What is the modules name?

I just typed "$acpifan" into my .conkyrc and it said "no fans?" This is starting to worry me.

I'm trying to follow the guide here: http://gentoo-wiki.com/HARDWARE_Lenovo_ … an_control, but #pwmconfig stops me. It says there are "No usable PWM outputs"

According to the wiki you linked, it's "thinkpad_acpi"

And did you follow Archlinux's wiki for the thinkpad t61 instead of using the gentoo wiki?  http://wiki.archlinux.org/index.php/IBM … d_T61#ACPI

Hmm.. I did that. How do you black list asus and toshiba's acpi?

# blacklist asus_acpi

and

# blacklist toshiba_acpi

?

Re: [SOLVED] Thinkpad T61p fan

Create a new file in /etc/modprobe.d/ (myblacklist or so) with exactly those two lines in it.

Re: [SOLVED] Thinkpad T61p fan

Did that. Thanks. Is there any way that I can, detect the fan spinning in real-time?

Re: [SOLVED] Thinkpad T61p fan

Install lm_sensors, run sensors-detect, see what module(s) you need for monitoring and put them into MODULES in rc.conf. A simple 'sensors' should then output what you want.

Edit: seeing your first post, you can define module options in /etc/modprobe.conf: options thinkpad-acpi fan_control=1 experimental=1

Re: [SOLVED] Thinkpad T61p fan

please bear with me, because this is the first time I'm doing this. I did

# sensors-detect

and just pressed enter for all the choices. And this is what I got as the summary:

Driver `coretemp' (should be inserted):
  Detects correctly:
  * Chip `Intel Core family thermal sensor' (confidence: 9)

Do you want to generate /etc/conf.d/lm_sensors? (YES/no): 
You should now start the lm_sensors service to load the required
kernel modules.

Now, I have lm_sensors installed, so I'll need to include it into my modules in /etc/rc.conf? Do I put "coretemp" (as said above in the summary) into modules in /etc/rc.conf as well?

For the second part, I just add "options thinkpad-acpi fan_control=1 experimental=1" into the /etc/modprobe.conf file?

Yes.

Yup.

But in general, I think your best source of information should be thinkwiki.org.

Re: [SOLVED] Thinkpad T61p fan

Aye. Me too. But the thinkwiki said to d/l this tp-fancontrol thing, and I have no idea what to do with it. I just migrated from Ubuntu where everything was served on a gold plate. So this is all rather new for me.

Right, I've added the stuff. Let's see how they do. I'll give an update after I restart my computer.

Re: [SOLVED] Thinkpad T61p fan

Right. After a restart, the modules loaded ok, but when I tried to run "lm_sensors", it said "command not found". However, running a yaourt on it says that I've installed it.

what? why?

Re: [SOLVED] Thinkpad T61p fan

'sensors'

Also, running 'pacman -Ql packagename | grep bin/ ' comes in handy if you don't know how some tools are named.

Re: [SOLVED] Thinkpad T61p fan

Wow, that's quite a lot of temperatures, but yes, looks ok.
The coretemp values should be the most accurate and the fans also seems to work.

Re: [SOLVED] Thinkpad T61p fan

Quite a lot of temperatures? ooo...k... I guess from your post that it's not a bad thing. But as long as the fan's working as it should, I'm happy. Thanks to dduong and byte for all the help.
