Yep, they work, this design has been around a long time. Its a thermistor inside the plastic, must be in contact with the fin to work. Slide up temp will drop. Not a big range, but this isn't a $4,000 reefer either. A thermistor is simply a temp sensitive resistor. Slide up it causes the electronics to drive the cooling system a little longer.
