Oldtimer glider, PIK-5b - airspeed data out from the sim and to the computer cooler fan

Hi,

I am building oldtimer glider (PIK-5b) to a real fuselage:

I am now asking for help to find a way to bring out the airspeed indicator data from the sim software (Silent Wings) and connect it to a normal computer cooler fan. The speed of the cooler would change depending how fast the user would be flying.

I found some info from SW forum concerning the output data:

Any kind of help is very highly appreciated.
