"Nobody"? How much "fan noise"? Compared to what? An anechoic sensory deprivation chamber? A jack hammer outside the office building? Your refrigerator? Car tires at highway speed?

> How much "fan noise"? Compared to what? It doesn't need to be "compared" to anything. Just a chart of noise in dB vs. performance would suffice. That way you can glance at the chart and say "at this performance level, I can expect it to make this much noise"

  It does need to be compared to something - 72dB is "loud" in a quiet room It's pretty "quiet" in other contexts

    It can just be measured and reported, and the user can decide for themselves?

      Honestly, almost no one understands decibels ... beyond "less if better" (for some things) :) I took a whole semester class in college on the physics of sound - decibels and loudness are just bleeding weird :)

You don’t really need to compare it to anything other than the 0dBSPL reference point. Standardize a laptop setup and environment, pick a listening position, measure dbSPL. A good position might be “1m from the center of the laptop base, at an elevation of 45°, while the laptop is on a flat, hard desk”. You know, more or less how people use laptops. Obviously you can go loose or specific with the description of the listening setup. You could standardize the room, you could standardize the desk, etc. I think the desk probably should be there, since it will reflect fan noise, and closer match actual laptop usage. You measure the A-weighted fan noise under different loads and publish something like dB SPL versus W graph.
