but I want this new build to be really quiet and still allow me to overclock.
It's a great cooler, nice for adding to the machine even if you aren't overclocking as it's near silent when in low rpm mode. It's good for overclocking too but I guess it depends on what chip, something like my chip is okay but something like a quad would probably need something like the Ninja / BigTyp VX. I did actually own a Scythe Ninja about a month ago, used it for a week and sold it on (wasn't as good as I was hoping and was little improvement for me over my AF7 Pro).I see you're currently using a Arctic Freezer 7 Pro. How's that?
