Hello,
I'm using on a dual xeon system lmsensors and pwmconfig for listing
and controlling the fan speed.
Lmsensors is configurated and checks the temperature of the CPUs,
but the fans rotate every time with
full speed:
CPU1 Fan: 5555 RPM (min = 2000 RPM)
CPU2 Fan: 5895 RPM (min = 2000 RPM)
CPU 1 Temp: +50.0 C (high = +75.0 C, hyst = +60.0 C) sensor = Intel PECI
CPU 2 Temp: +53.0 C (high = +75.0 C, hyst = +60.0 C) sensor = Intel PECI
On booting up the fans have got around 2000 RPMs but some minuts the
system speeds up on idle status
Can you help me please to configure the options correctly, that the
RPMs are only gown up if needed?
Hi Phil,
imagine you are an expert in the area. Then imagine someone sends you this
e-mail. Do you think you would be able to help based on the information in the
e-mail ?
Or, in other words, please provide sufficient information for
people to actually
be able to help. Kernel version, lm-sensors version, complete sensors command
output, and all relevant configuration (including pwm configuration) would be
a start.
Sorry my mistake, I have forgot to past the full data (it was a
little bit early on this morning and I was tired):
kernel version 3.2.11
lm sensors 3.3.1
Gentoo Linux 64 Bit
pmwconfig found this devices
hwmon0/device is i5k_amb
hwmon1/device is w83793
which are also used on lm sensors. The sensors config has stored
only the min/max values (the min values on the CPUs are set to 2000
RPM),
labels and some ignore values
Only the two kernel modules are build
CONFIG_SENSORS_I5K_AMB=m
CONFIG_SENSORS_W83793=m
all other are disabled
I hope this additional kernel modules are helpful:
CONFIG_THERMAL=m
CONFIG_THERMAL_HWMON=y
CONFIG_X86_THERMAL_VECTOR=y
CONFIG_ACPI_THERMAL=m
I don't know which option can be modifies to change this settings
and where I can start my search to find the problem. If I boot up
the system the CPU
fans do some "pulse", so the speed rises up and slows down, rise up, .......
If I run only once sensors the pulse is gone away, but the RPM increses
Do you have "fancontrol" running ? If yes, pelase provide the configuration
file. Also, please provide output of "grep . /sys/class/hwmon/hwmon1/device/*"
and the output of the "sensors" command.

I have only configures lm sensors and setup the values with pwmconfig,
that has create the /etc/fancontrol file with this content
