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.
But yes, sometimes up to 5x more than the comparative Arctic in common size categories where it basically trades blows for most metrics that matter. Arctic is seriously unbeatable in value:performance if you just need a basic fan without other QoL or aesthetic features.
120mm is the most competitive category, and it's the most obvious category how Noctua can't keep up with the faster iterating/innovating competition.
