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.
