Yes, I'm considering that and the possibility of a tiny thermistor circuit.
The good news is that it wen in well with a pair of carefully bent paper clips. is there anything that paperclips, donuts and gaffer tape can't fix?

the bad news is I had to delicately solder the lead to the fan pin and screw the neg under a PC board screw. (dont tell hugo or the support dept)
AND I had to take out the display board to give the lid enough clearance to slide in with the fan attached .
but it works , and is noisey.
from a cool start at 19C it has risen to and stayed at 33C for about an hour of constant playing
