For my new build I'm planning 6700k paired with Asus Maximus VIII Hero. I've been told that also Noctua NH-U12S cooler is a good choice and it's very quiet.

Scythe Mugen MAX recommended in this built, is incorrectly linked to Scythe Mugen 4 and the priced displayed ($50) in the article is also for Mugen 4. Mugen Max costs currently around $80. I'm not sure which is the typo. I'd like to know which cooler is actually recommended here.
