I don't think they dominate. Noctua used to be the best, but current reputation as far as I've seen is that the performance isn't necessarily better than the competition. You buy them for durability and supporting the engineering, but most (not some/fringe) DIY builders choose a cheaper brand.

It's a bit more pronounced in CPU cooling towers, they are solid blocks where durability doesn't play a role. Noctua is good but the top performer and market leader is Thermalright which costs a third of Noctua.

Do you have data to backup your assertion?

Cheap Chinese clones eventually arrive when a successfully company dominates a market.

It does not mean that they no longer dominate.

Nope no data, that's why I prefixed with "I don't think". It's a sentiment from six months of reading product reviews and forum discussions. I took some good time building a new desktop.

People were recommending Noctua for long term durability, sure. But seems it's a minority who's willing to pay the premium for that.

Some data would of course be interesting.

Edit: Mindfactory is one of the few that publishes numbers. On a quick glance (didn't sum totals) looks like Arctic leads, followed by be quiet! and Noctua on the third spot. be quiet! is a German brand so that gets somewhat biased.

		I did a quick data extraction on that linked Mindfactory segment, and be quiet! leads after all. As said, not quite representative but maybe indicative. `be quiet! 100.060 Arctic 60.850 Noctua 45.290 Noiseblocker 23.840 Xilence 23.050`

Noctua also provides free new mounts. I've had the same NH-D12 for over a decade now and whenever I switch CPU socket they send me a new mount for free.
