Cooling fan question

I have an '09 Ulysses with D&D pipes and a Buell ECM designed for these pipes. The bike runs great but the fan is basically ALWAYS running except when I come to a stop. It will go off and immediately then start again once I'm in motion. Does anyone know if this is normal? Concerned that my fan will have a very short life although it's been good for 10,000 miles so far. Also, if the fan does quit, is it essential to get it replaced immediately? I'm in a very cool climate in Upstate NY and rarely ride in anything approaching 90 degrees.

Do you have a RSS ? Is this the ECM you are using ? http://idspd.com/xcart/buell-xb12-08-09-d-d-ecm.html

If you can get into the ecm with ecmdroid or another program, go into ecm parameters and uncheck “speed based fan control”
