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 /proc/acpi/thermal_zone/THM/temperature. But I suspect it to be fake, it always shows 46°C. It currently shows values between 46°C and 47°C.
Also /proc/acpi/processor/CPU0/ contains information, this time it seems useful. For example cat info
processor id: 0
acpi id: 0
bus master control: yes
power management: yes
throttling control: yes
limit interface: yes
Doing an 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)?
