I don't know this for sure, but I would be astounded if a 3 bladed prop would turn less RPM's, for the same HP output. There is no free lunch. I don't believe that's how it works. I would imagine if there is a sound or vibration decrease, it would be because more than likely the 3 blades would be shorter, and as such have less tip speed. But they do look pretty cool.
