Noctua is just one of the apples of the PC world, brand recognition but only make overpriced barely passable gear, some of their fans here in AU are like $70 each, for fkn fans, they are an uppity brand that doesn’t deserve the adoration they get.
Why are you comparing a fan CPU cooler to AIO liquid coolers. Not really a fair comparison and not really useful to the consumers. Comparing the Noctura DH-12L to a Be quiet Dark Rock cooler is a better comparison.
First, I compare it with all the rest high-end coolers. Second, its price point is in the AIO territory.
Third, it is a CPU Cooler after all 😊…
However, if it’s not too bothersome… you can put different colors for AIO and Air to satisfy some readers.
By the way, …do you have in your schedule to review ThermalRight PS 120/120EVO?
I believe, it can level or beat Arctic LF (maybe even with its promo-price) in Performance Per Price ratio.
