Hi in the meantime I have assembled and tested the first 0 batch of my BB-AI-Cooler addon board. and it works fine. I use it in a project to be seen on element14presents where the board is enclosed in a tight case with a lot of other electronics and only two thumb size holes to transport the air. the 25mm fan is nearly silent(depending on the load it starts a high pitched sound sometimes) the temperatures are reasonable at Kernel R119 and even with PRU cores DSP EVE, serial com to an MCU and Opencv-python running on the main arm core at once it still performs within its limits.
So I can confirm the 25mm fan beaglebone recommended is sufficient but I prfer to mount in on my addonboard to allow for a bigger volume of air to be flown over the heatsink compared to mounting it directly onto the heatsink.

I Could not test the pwm/banBangcontrols for the fan because I was not able to get the GPIOs working with anything other than PRU,but this issue may be shortly resolve as Device tree overlays get released.

[mention:ea1cd9d4514b4dc891e01effad128e3c:e9ed411860ed4f2ba0265705b8793d05] Is not Debian on BB-AI on 64 bit OS?

That's a bit fan for a small board.
