OK I see...yeah it's really up to you as long as your CPU temps are safe (i.e. most people I've seen try to stay under 80-85°C with Ivy Bridge). But having the extra boost in cooling doesn't hurt either if you're OK with the noise. I do something similar to what you're thinking with my H80i. Generally, for day-to-day stuff I leave the fans set to the "Balanced" preset in the software which is the same as the middle setting on your H80. When I know I'm going to be doing something CPU heavy for a length of time (say render a movie in Sony Vegas, for example) I up the fans to the "Performance" profile.
But like I say, as long as your CPU temps are OK, it's really up to you.
