These are two laptops folding proteins with the Banano.cc team. These images are thermal camera images, captured with non-professional, low resolution FLIR camera.
The one on the right is more powerful with a GPU, one on the left - just 4 CPUs.
Temperature in the room may not be exact but it was above 20. Cold objects are more in blue spectrum, hot are red.
The hottest object is power supply. It is heated up to 56.6 C. (May not be exact)
The second one is only 40.
First, powerful laptop with a GPU was heating up to 50 ( again, it may not be exact but relative to other objects)
The second laptop was heated not so much, to about 39 grad.
The temperature above laptops was 0.8 grad higher (26.7 vs. 25.9). This makes sense due to convection. And kind of makes sense to place laptops on a floor if these are used for heating :-)
No, I do not plan to replace home heating with just 2 laptops but it seems there are some companies offering usage of computer produced heating to boilers and smart houses.

Oh wow that's so much heat. In my opinion the laptops aren't good for heavy work due not good cooling system.
