Looking at a couple of reviews for that card,
Power - Temp. - Overclocking - NVIDIA GeForce 9600 GT Roundup | [H]ard|OCP

your idle temp is higher than their load temps. Comes back to what I asked earlier; when was the last time, if ever, that you opened the case up and cleaned out the dust? If it has been a while or never, it will need a good cleaning (meaning removing components) to really get them cleaned out.
