did you modprobe it?

what did detect-sensors tell you?

Did you follow the instructions?

  * Run (as root) `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.

Definitely seems to me that you aren't following the instructions.

I notice but there is only one source for each version of the kernel.
It's the compile options that determine the ultimate kernel binaries.

When you install a kernel-src rpm it doesn't install it anywhere it can
be located by the rpm command since it isn't a binary and is installed
in the appropriate places in /usr/src/redhat.

I want to thoroughly discourage you from trying to compile these things
since you don't know what you are doing and would have to really learn a
lot. I have been trying to assure you that this has already been done
for you.

The detect-sensors command should tell you which modules to modprobe
AFTER you put the instructed lines into /etc/modules.conf

You have to follow the instructions in the 'Quickstart' file as I have
quoted you now twice.
