There's a great difference in fans. You might find a quieter one. A resistor might be enough to help, though. Two things I noticed on mine are that the heatsink is not at ground potential so be careful, and there is a snubbing resistor which will overheat if there's no continuous air flow. So mine sits idle on the shelf.
