It disappointed me, though I wasn't surprised.
The thing is, for objective questions with objective answers I've always thought that a basic search engine should be able to properly answer them. And in most cases they have.
Though in this instance I needed to equate one metric with another where there is great debate between competing technologies. And no clear way to bridge this gap under the circumstances.
I guess I was testing AI by "putting it on its ear" and it failed. Oh well...
My end result was concluding that if you choose to use a Noctua product, you have to interpret their thermodynamics by their metrics and no others. In other words, take their word for it as an act of faith and little else. But then this may also reflect their arrogant position in the industry. That they are the best, so they can afford to take such an attitude.
Which in their mind may also bolster their pricing structures, which are often outrageous compared to competitors like Thermalright.
When I build a PC, while I may not seek to build the most powerful system, I always try to use the best known components available. Even in the case of Noctua or Thermalright cooling solutions. One outrageously expensive, one amazingly affordable. While both seem to do quite well in the industry.
