Thanks for this !

When assembling again, I noticed that at the contact between the micro-processor and the cooler the thermal paste there was a very small amount of thermal paste.

I had none to add, therefore I reassembled as is.

After starting the machine again I note that the cooling fan never stops.

I suggest that at reassembling should thermal paste added.
