Hi,
I have no idea about other distro's, but I haven't found a machine yet running SL4 or SL5 that fills in /proc/acpi/thermal_zone/ The tool in Scientific Linux for finding temperatures, fan speeds, and other stuff is lm_sensors.
To get it setup, make sure it is installed
  yum install lm_sensors
Turn it on
  /etc/init.d/lm_sensors start
Then run the configuration tool as root
  /usr/sbin/sensors-detect
I always just take the defaults, so I just hit return on everything.
After it is done and written out a config file, restart lm_sensors and see what sensors are detected and being monitored
  /etc/init.d/lm_sensors restart
  /usr/bin/sensors
It usually has way more than you care about. Most people don't care about the memory cards that much, so you can edit what get's monitored in /etc/sysconfig/lm_sensors I can't remember if lm_sensors is on by default or not, but just incase it isn't, turn it on by default
  /sbin/chkconfig --level 345 lm_sensors on

Hello,

we have to use SL4.6 on a Dual-OpteronQuadcore system and want to get the
thermal info for the cpus.
But  /proc/acpi/thermal_zone/ is empty. :(
We use kernel 2.6.9-78.0.1.ELsmp.
It's working without any problems when installing another linux
distribution like Slackware/SLAMD64 - but we should use Scientific
Linux....
Does anybody know how to get it working?

Cheers,
 Marcus
