There is a temperature sensor on some models but it isn't exposed via the sensors framework at the moment. The code has a notion of profiles as mentioned here: http://xorg.freedesktop.org/wiki/RadeonFeature/#index3h2 The choice of profile isn't exposed to userland currently. Newer upstream versions of the radeon code default to dynamic power control managed by the hardware (dpm) which apparently helps reduce noise quite a bit but that will have to wait until we have newer drm code.
