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
