After my update above, my GPU temperature was very high all the time, getting above 80 at times. I use Compiz Cube, so I configured it to have 0 transparency while not turning, and added a wallpaper (had just a black background, and my GPU temperature now hovers at around 55 degrees. Evidently, the fancier you get with your desktop settings, 3D effects, etc, the hotter your GPU will run. No loud fan at all since my last change.
