Hi, Welcome to LQ!
LQ has a fantastic search function that may save you time waiting for an answer to a popular question.
With over 3 million posts to search it's possible the answer has been given.
do you have lmsensors installed?
At least the CPU fan is probably controllable via the BIOS but that should be independent of the OS. Depending on your motherboard you may be able to control the case fan(s) if you swap them for types that connect to the motherboard -- for that, use lmsensors' fancontrol script.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Just follow the directions, the defaults are assumed.
LM_Sensors should install a startup script for your system type,
If you can't find a RHEL 5 .rpm, try to install from source
(this might open a can of worms for some people, new!)
It is probably on the RedHat install cd.
