How do I monitor temperatures, fans and voltages with OS drivers?

[sonnet]

My understanding is that the code is already in the kernel.
But how can I launch the 'monitoring'?
Is there any command I should execute in the terminal?

The info you want is in /sys look around and find your graphics card and get your info

(i know this is *really* helpful, but I do not have access to a system with a radeon card at this very second)

"sensors" will also display it

Hi ,thanks sensors did the trick, although I'm not happy at all with the numbers I'm seeing.
