It's luxury watch engineering for gamers. You do not need it, but it's kind of charming when anyone competently takes a niche to its extreme, imho.
That said, on my last PC build I ended up buying Pure Wings 3, which are quite competitively silent at similar airflow and much cheaper.
And white. Because I do like silly pretty PCs, as long as they don't have RGB on.
Functional premium product at premium price. Cheaper mid-class does the job most of the way. But I suppose there is slightly better characteristics and probably higher reliability in design. Not a fake luxury like too many products these days.
I suppose we should be somewhat positive that some company still aims to deliver best possible products. Not just products with cheapest possible cost and some perceived luxury if even that.
