Looking at the schematic and PCB, an inductor between mosfet source and ground, as well, might help.

Thank you for suggestion
I don't know, it might have some influence, but we have these lines even when cooling system is not plugged (ie no TEC on board)
We are searching on hardware/PC side, since some configuration seems to give more bugs than other (old laptop vs brand new vs arm ...)
