I recommend enabling "wait for vertical refresh" from your graphics card control panel to limit the game frame rate to your monitor refresh rate (usually 60 fps). This way the game will still be perfectly smooth, but does not render more frames than your monitor can output. This way the GPU is utilized much less, and will cause much less heat. It's likely that this change alone will drop your GPU usage and heat so low that the game should run stable.
