Thermocontrolled Fan, ver 2
This small modification in the older schematics made it sensible to temperature.

Main difference from older circuit is that I used one of error comparators for NTC thermoresistor. R3 and R4 must be equal or something near to make temperature adjustments easy. As at this moment I have only one potentiometer at hand so I removed fan speed control.
