This might not be the answer you're looking for.... but the best speed to set both fans to is simply let the system control the fans instead of SMCFanControl. Trying to set the fans to a higher RPM to induce better cooling is only going to wear them out faster thereby creating future problems.

As to the increased temperatures in Windows.... How are you using Windows on your MBP? From Boot Camp or from a VM? If from Boot Camp, post back and I'll suggest a small Windows program that will help control the higher than normal CPU temperatures without modifying fan speeds.
