It will get louder, simply because it's spinning faster - perfectly normal and expected behaviour.
If it sounded different to normal - making a clicking or grinding sound - it would be a different matter. Regardless, I can't see that a software program could ever speed up a fan beyond its designed maximum, it should never be possible.
Fan life shouldn't be measurably shortened by running at max speed all the time, your hardware should actually last longer (in theory, and not measurably longer) as it should run cooler.
