GPU - ATI Radeon X1650 Series
DirectX - Just updated to the latest off of Microsoft's website (March 2009 version of DX9.0c)
Drivers - just downloaded them less than a week ago.
I pulled up Catalyst Control Center and didn't find a place to check the temperature.
Same with GPUZ. The closest I found was the GPU Core Clock and GPU Memory Clock charts, which remained constant no matter what I did.
