I enclose below my version PCB circuit shown here:
http://diagram4schematic.com/230vac-temperature-fan-control
It is a circuit that controls the fan speed according to the temperature. The circuit is powered at 230V and uses a thyristor as shown in electric diagram I reproduced it and I attached it below.
Regarding the operation of the circuit, depending on the fan used, switched depending on the temperature is fast enough but if this does not bother the application they are going to use it, then we can say it's a scheme variable 230VAC is very useful.
I used 17W fan - this type:

I studied the possibility to connect an RC snubber between terminals AK thyristor but not required in the application studied and made practical. Or in other words, everyone has the choice.
I attached some pictures below.
