lm_sensors fan

Nareto · 2011-04-01 10:35:35

Hello, I'm following the wiki instructions here:

https://wiki.archlinux.org/index.php/Fa … ng_fan_div

but I can't figure out what chipset I have. Below is the output of sensors-detect and sensors.

The computer is a Toshiba Satellite A200 laptop with an Intel Core 2 Duo.

Any help appreciated

renato@tosharch /etc $ sudo sensors-detect

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): 
Module cpuid loaded successfully.

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'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      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 82801H ICH8
Module i2c-dev loaded successfully.

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 overwrite /etc/conf.d/lm_sensors? (YES/no): 
Copy prog/init/lm_sensors.init to /etc/rc.d/lm_sensors
for initialization at boot time.
You should now start the lm_sensors service to load the required
kernel modules.

Unloading i2c-dev... OK
Unloading cpuid... OK

Well, that looks like the laptop simply doesn't have any supported monitoring chipset ... that's not too uncommon.
If the cooling is working fine otherwise, I wouldn't worry.
You could test it by running 'cat /dev/urandom > /dev/null' (Ctrl-C to cancel) and listening to the fans; should get noticeably louder after a while.

Nareto · 2011-04-03 20:43:23

is that simply a way to see if fan speed increases with CPU load? yep, it does. Unfortunately I do have cooling problems, and that's the only reason I'm looking in lm_sensors, to try and set the fan up full speed all the time or something (that probably would be too much, but I'd like to experiment)

so there's no hope for me to control the fan speed?

cheers

Hop to this and adjust the script to your needs. It allows you either to manually set the fanspeed or just switch back to auto-mode.

happy tweaking

Have you tried this on anything other than an EeePC? I have yet to come across anyone who's successfully gained manual control over the cooling fan of a Toshiba laptop, and I've been looking for some time. Toshiba (along with Sony, I hear) are the worst violators when it comes to "forcing" their customers to use Windows; a debugged DSDT file may be necessary. Otherwise, if this works, I may have to use it myself.

itman · 2011-04-04 18:20:45

Nope - just used it on my eee. But I guess you could use it on that Toshiba too. Just give it a try...

#path may be other in other kernels, mine is kernel-netbook, so check it and correct, otherwise it won't work!

see that pwm1_enable points to your correct directory and file.

happy trying and good luck

uhm I don't quite understand what the script is doing but I don't seem to have any relevant files in /sys/class/hwmon, only related to CPU temp

renato@tosharch /sys/class/hwmon $ ls
hwmon0  hwmon1
renato@tosharch /sys/class/hwmon $ ls hwmon0/
device  power  subsystem  uevent
renato@tosharch /sys/class/hwmon $ ls hwmon0/device
driver  hwmon  modalias  name  power  subsystem  temp1_crit  temp1_crit_alarm  temp1_input  temp1_label  temp1_max  uevent
renato@tosharch /sys/class/hwmon $ ls hwmon0/subsystem
hwmon0  hwmon1

Aehm - what are your boot-parameters? You'll find'em in the menu.lst in /boot/grub/ Try to add

acpi_osi=Linux

reboot and run that sensor-detect again.

are you aware of those "omnibook" things? Kernel module for HP OmniBook,Pavilion,Toshiba and Compal ACL00 laptops. That might help too...

Otherwise I'm out of ideas...

Nareto · 2011-04-11 18:04:17

tried both the omnibook kernel module and the acpi_osi option, still same situation... I guess I won't have fan control.

It's strange because I could swear that sometime ago the fan actually sped up and down, while now it's constantly in "slow mode".... any more hints on where to dig?

cheers
