What does it hit at load and if you say 39oc then there is your answer.

When its loading most parts will be under heavy load for graphical and for processing to load in all the programmes and for the desktop e.c.t.

so 39on the gpu is not bad.

Powercolor 3850 uses a Zerotherm heatsink fan and so it performs much better than the stock one.

Many reviews showed that the load temp is in this range of 54-64C, depending on the ambient temp and the loading software.  So, unless your ambient temp is a much lower than average, I suspect the sensor might be a little off to give a load temp of 39C.

 

The reviews below all used RivaTuner to check the temp.  Two reviews mentioned that the fan runs at 100% power/rpm all the time and cannot be controlled, in its default state. 

So, I suppose you will have to devise a way to control the fan speed.

Uninstall everything, Catalyst, Ati Tool and whatever third party softwares installed.

 

Install this Catalyst package then make sure the clocks are full throttle. Check the temperatures again under load.
