I have a question that would like for your comments

With GPU-Z we can get GPU's temperature information from 2nd and 3rd sensor; to my observation the 2nd and 3rd sensor always indicates around 5-7 degree hotter than the 1st sensor.

With Linux, how can we do that? I mean getting the additional information the 2nd and 3rd sensor

And the sensor which is reported by "aticonfig --odgt" is also the first sensor listed in GPU-Z? Or it is the 2nd or 3rd? Googled for several hours but I could not find anything useful.
