Hi,
I recognize that it seems that the GPU temperature Aida shows with a Geforce 8800 GT is too low.
For example Aida shows 55°C, but Ati Tool and the old Everest Version both shows 63°C which is the correct temperature I guess.
It´s strange that the GPU temperature is everytime equal to the GPU environment (example 55°C), maybe this could the problem?
GPU memory temperature looks ok..
