Thermal Monitor & automatic shutdown on over temperature event
Bob
if either the CPU or the Hard drives overheat.
My motherboard is an ECS K7S5A which has a it87-isa-0290 sensor chip
from sensors-detect
# Probing for Super-I/O at 0x2e/0x2f
# Trying family `ITE'... Yes
# Found `ITE IT8705F Super IO Sensors' Success!
# (address 0x290, driver `it87')
#
# Probing for Super-I/O at 0x4e/0x4f
# Trying family `ITE'... Yes
# Found `ITE IT8705F Super IO Sensors' Success!
# (address 0x290, driver `it87')
Sadly with this motherboard it's not possible to read the on die
thermistor without breaking out the soldering irons and modifying it.
I can't find a way to set the "Overtemperature Shutdown limit" mentioned
in the it87 documents
http://www.gelato.unsw.edu.au/lxr/source/Documentation/hwmon/it87
and I've tried setting temp3_over (CPU) to 40 and used burnK7 up to 53
degreesC (actual is probably +10 ~ 15) and the system doesn't shutdown.
I've seen people recommend using sensord to shutdown on overheat but
can't see howto, also this wouldn't do anything for the hard drives,
similarly hddtemp seems to just do reporting with no option to shutdown.
collectd has options to monitor both but no tools that I can see to do
anything if an error condition arises.
My reading has led me to believe that the kernel can do at least the CPU
part of this for you, if you've got a better supported sensor chip,
which I don't, but I can't be alone, so what do others do in this situation?
Thanks, I'm not subscribed at the moment so could you please CC me on
any replys.

gets to high and I'm not at home, or asleep I want the system to shut
down.
I wrote this small script using sensors to detect and warn high temps.
At very high temps execute shutdown.
A wall-message and a 30 sek timeout is good if I'm at the desk and can
connect a fan and abort the shutdown. I run the script with nohup.
regards, David.
#!/bin/sh
HIGH=70
SHUTDOWN_TEMP=85
export HIGH
export SHUTDOWN_TEMP
while true
do
# read temp
TEMP=`sensors|grep 'CPU Temp'|cut -d+ -f2|cut -d. -f1`
if [ "$TEMP" -gt "$HIGH" ];
then
echo "High temp: $TEMP > $HIGH" | wall
sleep 2
else
if [ "$TEMP" -gt "$SHUTDOWN_TEMP" ];
then
echo "To hot, shutting down in 30 sek.!" | wall
sleep 30
sudo shutdown now
else
echo temp OK: $TEMP
sleep 5

fi
done

Hi David
A shell script did occur to me, but I thought with so many hardware
monitoring daemons, and so many hardware monitor logging daemons, and so
many GUI widgets for outputting the results of the previous 2 in
practically every desktop environment ever conceived, some of which
allow you to automate tasks on event conditions, there *MUST* be an
option for headless systems other than some loopy shell script. (pun
intended, not offense)
Have you tried to get sensord to control your fans? I tried this first,
have the fans off until the CPU hits 50 or whatever, sadly doesn't work
with my MB (which was very cheap 4~5 years ago) but you may have more luck.
Nice script though, short, obvious, to the point, I may well end up
nicking it and adding an hddtemp call.
Sorry for relaying out your email, some people get really narky about
top posting.

Are we really the only ones? Just thought I'd post a link to the thread
incase someone relevant missed it over the weekend, which is easy to do
on such a high volume list.
http://groups.google.com/group/linux.debian.user/browse_thread/thread/777342699b05e16c/dee09f811a63870c?
if that works.
Thanks.
