One thing to watch out for is the hysteresis in these devices. The device I
pointed out will turn the fan on at 30 degrees, but it won't go off again
until the temperature drops to 20. If your room is warmer than that it will
never turn off!

Probably why I've seen the sensor directly in front of the fan. when the
fan is operating it is getting cooled faster than the rest of the
cabinent and thus actualy turns off at a higher temperature.

OTOH, unless the fan noise is a problem, does it matter. Fan just
stays on until power to unit is removed, aka it might lert you to the
fact that te entertainment cabinent is still using power when not in
use.
