After running sensors detect, yes was chosen, but I am confused about the "run '....' to load them command! If I need to do anything, what or how do I do that? Thanks! (I still have no fan, BTW!)

Do you want to add these lines automatically to /etc/modules? (yes/NO)y
Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run 'service module-init-tools start'
to load them.
