Go for a Artic FReezer A30 , I use it and without a doubt really quite when IDLE and underload. And great cooling . I get aroun 65 degrees while gaming.
That one is compatible with your CPU's socket, just make sure it will fit in your case. If your case is too narrow to fit a 120mm cooler, you may have to use a 92mm cooler instead. It will be louder, and not cool quite as well, but still much better than stock.
