Hi,

Thanks for the info, maybe I just needed to write it down to really get it working:)
I have figured it out that system fan is pwm2 (maybe it's temp shows -70, because there is no system thermometer) and after enable is set to 1 it is controllable via pwm2, so now I can write a script that reads hddtemp and set's it to the right value.

Thanks!
Tamás

How would it know ? That is why the configuration file supports the "ignore"
statement. Also, why is it strange ? There is no requirement that a board vendor
MUST connect sensors in a certain order.


shows -70 degrees:
# cat /sys/class/hwmon/hwmon1/device/temp1_input
33000
# cat /sys/class/hwmon/hwmon1/device/temp2_input
-70000
# cat /sys/class/hwmon/hwmon1/device/temp3_input
46000
If I get the meaning of the readings well, that 46 Celsius is the
core temperature. It would be a bit surprising if that is true,
cause there is no load on the machine and the CPU is taken back to
750 Mhz, I would expect a lower value there too.


That really depends on your CPU. Yo could try to compare it with the output
of the core temperature sensor if your CPU supports one.


The pwmX_enable values are 0,2,2 though I can echo anything to it, I
can't make the fan stop or change it's speed.


Setting a value to 1 should enable manual control. 2 is automatic, 0 turns it
off entirely. CPU fans can not be turned off, so if one fan is the CPU fan
it would not be surprising that it can not be turned off.


The reason I want to this is that I have made a special case for the
machine and the fan I have connected to the system fan is only
responsible for HDD cooling, it should controlled by the hddtemp
values. But anyway it would be better to have control over the cpu
cooling as well cause I think it is overcooled now, which is simply
wasting energy.

Cheers,
Tamás

Most likely it is not connected to anything.


seems to good. Also the fan speed readings seems to be ok (I am not
100% sure). What it really does, that hwmon1 is created and there
are changing values so at least it is partially working.
I have tried to use pwmconfig to configure and also tried to echo
values I could think of, but I could not set (nor pwmconfig could)
it's speed.

Fan control may be in automatic mode. That is the case if pwmX_enable
returns 2. If so, you are most likely better off by leaving it alone.
