I wonder if it has something to do with the cards being used? Mine never overheats either. I use fast cards, 45Mbs minimum. If your buffer is constantly being used because the camera writes to the card slowly, then maybe that is adding to the heating issue?

Just a thought, no basis in actual tests...

I think the card type can in fact, if not exclusively, be at cause.

Another shooter was having his 550d overheating in 2 minutes at normal ambient temperatures until he replaced his memory card.

Here's the link, it might make you laugh. :)

I find that my 7D only overheats when the CF card is over 85% full. Otherwise no issues at all.

First time I used my 7D at an outdoor wedding, it overheats like crazy, despite standing under a shade. I had to switch off and on almost every 15 minutes, luckily it didn't die on me during the important parts.

Following that, strangely enough, it never overheats again. I thought the firmware update fixed it and I did upgrade my CF to a 60MB/s.

Although I haven't yet try it in the summer season here in Australia where the ambient temp is 30-40 deg C. Maybe I should prepare some of those ice packs now as I'm entering summer in a month time...

The latest firmware helped a lot and since updating it I have no heat warnings anymore. Before the update it happened mostly in 720/50p mode as if the camera had to "work harder" resulting in getting warm.

Thanks.
