Good day everyone, So I've been messing around with the ESP32-CAM with the OV2640 camera and decided to plug in an OV5640 instead. First two things I noticed were that the LED functionality was gone and that the board gets really warm really quickly. But what I'm actually making this thread for is …

I swapped them back around about an hour ago, still seems to work just fine. I don't think the board was damaged yet. By really warm I don't mean hot, just really warm. I didn't let it run for too long.

Its the camera overheating, add a heatsink to it; [The Great Search: A Small Heatsink for a Camera Module #TheGreatSearch #DigiKey @DigiKey @Adafruit]

Thanks, I've already ordered some

I have bought a Esp32-cam within ov5640 and I have exactly the same issue. At the moment I will try to attach a heat sink to understand if it is sufficient….

That is a very bad sign, and the replacement is clearly a bad idea. Don't count on the ESP32 board working reliably after this experiment.
