After successfully installing
lm-sensors on my fresh Turnkey Linux I called
sensors-detect. Alas, it reports it can not detect any sensors. I did try the 2010 script that comes with my Turnkey distro, also I downloaded the current one.
I run a linux kernel 2.6.32-5-686 on a good old Dell D400 Latitude -- an "Intel Pentium M 1.8GHz" inside (family 6, model 13, stepping 6), as told by
/proc/cpuinfo. I gather that
coretemp would be the driver of choice.
It seems the key point is that the kernel module
coretemp does not fint and devices. If I run
modprobe coretemp it says
FATAL: error inserting coretemp (.../coretemp.ko): No such device
What "device" is meant? Is this the correct driver?
I do get some at
But I suspect it to be fake, it always shows 46°C. It currently shows values between 46°C and 47°C.
/proc/acpi/processor/CPU0/ contains information, this time it seems useful. For example
processor id: 0 acpi id: 0 bus master control: yes power management: yes throttling control: yes limit interface: yes
echo 4 > throttling (4=50%) actually does have the effect that the CPU seems to be running slower. I also tried
6 (25%) and 7 (12%). Alas, the fan keeps humming nonetheless.
Any idea how I can silence down this excellent piece of computer without ripping out the wires (which probably is not a good idea)?
