I used to really like Noctua fans, for a while they were obviously the best fans by a significant margin. But for all their tight tolerances and exotic materials and a high price to match, they generally don't outperform BeQuiet's more regular materials but use-focused fans that are half the price. Nor are they significantly better than Arctic's general purpose fans at a quarter the price. It'd make more sense to jus…
2×? Try 5× for the Noctua NF-A12x25 compared the the Arctic P12 Pro that matches or beats it in most metrics. Which isn't to say the Noctua fan is bad, it's just a luxury product for reasons other than performance.
In general, yes, Noctua is overpriced and Arctic is an incredible value, but when you want to optimize your silence/performance ratio, it's still Noctua, BeQuiet or (sometimes) Thermalright.
