I have a "mechanical area" behind the wall and was thinking of adding an air return with a pair of 120mm fans activated by a thermal sensor.

Does a solution like this exist already ?

I did this with the thermal sensor. 2x noctua 5V fans and an old phone USB power adapter. Works really well though the fan runs at a set speed.
