Probably not KDE, but possibly X itself.  Maybe it isn't the CPU, but
the GPU that is overheating.

The radeon driver has a "DynamicClocks" setting (man radeon).  Do you
have this option in your xorg.conf file?

Do you have /proc/acpi/thermal_zone/THM*/temperature?  If so, just do:

while sleep 2 ; do clear ; cat /proc/acpi/thermal_zone/THM*/temperature;
done

Again, did you check /var/log/messages to see if anything interesting
shows up there.  If you have Machine Check Exception options in your
kernel, many overheating, fan, or voltage problems should get reported
there.
