I and other's have had this exact problem and for all of us that I know of, it was in the cabling just above or inside the print head. So you may be able to debug this just by poking the cabling. Literally, poking it with your fingers.
If you have a friend with a multimeter and who knows electronics, this is a very easy thing to debug and repair. Otherwise it's a big undertaking (ordering and replacing parts one at a time).

There is and that could be the problem but unlikely. It's the same sensor that knows the temp of the nozzle but a different circuit.
More likely it's a bad wire in or just above the print head. Heat the nozzle to 80C so it starts spinning the fan. Then slide up the black mesh that covers the wiring above the print head and touch/push/play with the cabling. I believe the wiring is a black and red wire - at least on the fan end of the connector. Play with things to see if you can get the fan to fail.
Maybe also take the head apart (just those 4 long screws). Don't burn your fingers on the heater block.

Thank you very much for the reply. I will check the cables, there is not much to do otherwise I guess.
