How to reduce annoying fan noise

The most annoying thing about my Librem 15v4 laptop (and perhaps other models) is the on-again-off-again fan noise. At least, it does vary the fan speed based upon current need, but the maximum speed is too close to a tornado for my liking. I suspect I’m not alone in this regard. In the longrun, I hope that Purism: (1) somehow improves the acoustics, perhaps by the use of a bigger heat spreader, more vent holes, more thermally conductive case material, better vibration isolation (like a Lexus), …

Which means, just perform the opposite configuration.
