The username was a bit of a giveaway.
Their claim about Noctua is also not correct, or at least not generalisable to all coolers. I upgraded my CPU recently to a Ryzen 9 5950X, so needed to upgrade my cooler. The NH-D15 came out as one of the best options (that were also available second hand) when looking at cooling performance per dB. That ratio is what matters.
I ended up spending about $45. It ended up not having all fan clips with it, but Noctua sent those to me for free.
