Normally, you can just hook it up to a temp sensor for each speed.
160 deg. = low speed
180 deg. = high speed
Just an example.

I had an adjustable fan controler on my last BMW and have installed several, you can buy or order them where they sell aftermarket fans. Real simple the sensor pushes into the fins on the outlet side of the rad and an adjustment that kicks a relay sending power to the fan at the set temp. Two might work for your setup. They run about 35-45+ bucks.
