In my experience, mine seems adequate at cooling in its stock configuration. I measured some temps last night after playing over an hour of video. I could feel the warmth on the back plate but it never got over 50C. Your mileage may vary however, especially if playing games. I did see some suggestions on the forum about putting a thermal pad between the heat sink and back plate which might drop the temp a few degrees. It would be great if you post your results before and after the mod.
