beauty about rpm system is that it is already compiled and installed.

if you want to compile it yourself, you will need source for kernel and
compile it yourself - this is one of the modules of the kernel. Yes, you
would have to download and install kernel-source file

I had expected that you would read the "QUICKSTART" and just

  * Run (as root) `prog/detect/sensors-detect' to detect your hardware,
    put the lines it suggests into /etc/modules.conf
    and enter the modprobe lines sensors-detect suggests.
    Add the line `sensors -s' after the modprobe lines.

  * Reboot, or else type in the modprobe lines and `sensors -s'.

  * Run `sensors' to see your output.

knock yourself out - you are on your own here since there are parts and
pieces that may or may not work. They probably have rpm's - see if they
have one for RHEL 3
