Great !
will try it, I want to monitor my CPU's temp

Hi,

This thread is great - I finally got all my sensors working but at the same time my CPU fan startet to run in high speed mode.

Does anybody have an idea how to check this problem - because now it is very noisy...

@root echo "120" > /sys/bus/i2c/devices/*-0290/pwm*

see if something happens

Hi,

this gives me just this message:

bash: /sys/bus/i2c/devices/*-0290/pwm*: ambiguous redirect

These files (pwm1 to pwm3) exist and all contain 240.

However when I do it file by file it works !

What did I do by this change from 240 to 120 ? The indicated fan speed at gkrellm as well as ksensors dropped to 0 (zero). If I pass over a "160" than it goes to about 2660 rpms - below again zero. With "240" it was 4200 rpms. Hopefully this will not "hard" limit the fan (does mean that it will never be above these values even when the CPU becomes hot)...

Anyway thanks a lot for this excellent and fast reply...

that just lets you control manually how fast the fans spin.
i use 4 settings for my cpu fan ( a zalman 7700cu ) :
48, 144,176 and 240
I dont know how much it translates into rpm. however when i run the cpu at 1gz i turn the fan off by echoing the 44,
and the other settings as needed - when compiling stuff I set it to max speed ( 240 ).

i just have all of this in keybindings so its a rather simple task to change both fan speed and cpu frequency on the fly.

...so read it that it really "hard" locks the fan speed to a certain speed. But this might (in bad cases) lead to an overheating in case I set it to low speed (noise) and forget to increase it when I do something which needs full power of the CPU (such as sytem update or long compiling sessions).

However I believe that the danger would be rather small but do you think that a small script checking the CPU temperature an triggering the correspondig value would be nice ? Maybe there is such a tool out there - does anybody know one ?

hi,
I've used this before but now after a reinstall I can't get it to work anymore, I keep getting an error:

Code: Select all

!!! ERROR: sys-apps/lm_sensors-2.9.1 failed.
!!! Function pkg_setup, Line 39, Exitcode 0
!!! CONFIG_I2C_SENSOR not detected

any idea on what I should do?

ikaro · Post by **ikaro** » Wed Jul 27, 2005 9:15 am

thats not any error - the error its in the block over that, last 40 lines or so

swizec · Post by **swizec** » Wed Jul 27, 2005 9:52 am

oh yeah

these are the last few lines:

Code: Select all

 * Determining the location of the kernel source code
 * Found kernel source directory:
 *     /usr/src/linux
 * Found sources for kernel version:
 *     2.6.12-gentoo-r6
 *
 * lm_sensors-2.9.1 requires CONFIG_I2C_SENSOR to be enabled for non-2.4.x kernels.
 *

I have all the i2c stuff compiled in the kernel though...

i have this:
( grep I2C /usr/src/linux/.config )

Code: Select all

# I2C support

According to the tutorial on the previous page (2), the hardware sensor chip shall be compiled into the kernel after you emerged lmsensors. Well, Lm_Sensors cried out in anger for this so, I had to include the hardware sensor chip before emerging lm_sensors.

yeah, I managed to solve it, seems I didn't include the chips in the kernel from some strange reason...

anyways, it worked after I added them

Hi,

I built a water cooling system for my pc and so far it working pretty well! I'm looking for a script or program which can check my cpu temperature and if temperature is too high (>55 C for instance) then do a shutdown (in case my pump stop working). I checked my BIOS and it can't do it. (it will shutdown pc only if fan stop working).

Anyone can help me?
Thanks.

Code: Select all

For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!

Any ideas ?
sysfs is mounted of course.
And there was only one use flags (which I enabled) for lm_sensors..

Thanks !
