FWIW on my 50p, I get (Currently)

temperatures:   39 47 33 73 28 -128 26 -128
fan_speed:      3755
fan_offset:     0x84
commands:       fan_offset <offset> (<offset> is 0x00-0xff)

running xorg 6.7 (because I was playing with the r300 drivers late last
year & haven't updated again)
and the ATI temp doesn't seem to cary from 72-74C. The fan seems to sit
around 3700rpm always as well.

DynamicClocks is enabled... But not used on this version... So I updated 
to 6.8.2-rc3. Not a great deal of change. And this is essentially at 
idle. Anyone got any suggestions on how to decrease the temp of the GPU?

temperatures:   35 45 29 69 25 -128 23 -128
fan_speed:      3762
fan_offset:     0x84
commands:       fan_offset <offset> (<offset> is 0x00-0xff)
