Somewhat unrelated anecdotal praise of Noctua: due to various life factors, I hadn't built a PC since maybe 2010 or thereabouts - something I did relatively often before then and had quite a bit of experience with. Then a few months ago I finally did it again. Forgetting about the absurdity of the RAM situation, I gotta say my biggest surprise was cooling. I wanted a quiet media center machine. The internet and friends kept recommending Noctua. While researching, I got a bit of a cult vibe, and their prices seemed a bit stiff. But I went for it, with some hesitation.
Goddamn was I wrong! Their CPU coolers are the most well-designed, thoughtfully planned, amazingly performing consumer product I've seen in a while. 10/10, highly recommend! I'll use them for all PC cooling needs going forward.
