If I were you I would keep it where it is. I wouldn't want to cool too much and in another day or so as the fermentation slows, it should start moving closer to the ambient temp (59) anyway. You could throw a small fan on it for the next day or so if you have one, but I would be careful risking too much of a temp swing. 71 deg. is on the high side of this yeasts temp, but I don't think I would be too concerned with off flavors. On another note, it is pretty impressive that your brew is 12 deg. over ambient temp. That Pacman yeast is aggressive! Good luck.
