Hey!
I've just installed Magic Lantern on my Canon 1100d/T3, and I have noticed some kind of overheating during video mode.
The temperature arrives at 51°C after about 10 minutes of usage, and it happens even if I'm not constantly shooting.
So, should I uninstall ML? Will the camera explode in my hands? Will it do permanent damage to the camera's hardware? Would uninstalling Magic Lantern solve the problem? I hadn't noticed any overheating before installing it.

Note that when it reaches that temperature, the number is marked orange.

Sorry for my broken English. I couldn't explain it better than this.

Thanks :)

What led you to the conclusion that 51C = overheating?

What was the actual temperature of the camera without ML, and what is the actual temperature with ML, measured using a real thermometer?

Do you think that Canon might have put some kind of safeguard for overheating?

What do you think is a normal operating temperature for high-density silicon-based integrated circuits?

kd1m: Without ML there is no temperature displayed. If Canon's treshold is reached you will see overheating warning.
Now check again:
Press Set button during startup (=plain Canon code running), enter liveview and wait for 10 minutes. Now take a pic and check temperature for this pic via exif value.
Redo (after letting the cam cooling down for some hours) with ML running.
I bet you will not see that much difference ...

Well I don't know, I just thought that it was a quite high temperature, as it was marked in orange (not a very calm and reassuring colour, is it?).

I don't know precisely but I'm sure it's never been as high before. I could feel it, it's never heated that much, even during summer. The thing is, it's the grip that's heating, not the battery. I have tried using a shoulder rig and never touching the camera, the result was the same. But the battery stays warm, kinda room temperature.

Yes of course, but can it fail?

Will do. Thanks.
