Based on this, the fan is rather loud. I guess that's how they're able to maintain the sustained performance numbers.

  Well, they usually ship unlocked CPUs, where other vendors often power-throttle the CPU. I am not a "fan" of the fan noise, so I checked and the EC firmware was open source. It was possible to raise the fan tipping point to run the laptop hotter and more silent. People have also tried to set the power clamping later. That works and is equivalent to limit it in the BIOS. Key point is: this does not mean you have to run it that way. Add a power profile, l configure the fan curve, enjoy.

Those power figures make no sense, I'm not sure I get it. How could it run for more minutes than the battery size divided by average power draw would imply?

  That is be power draw at the outlet [0]. There is probably loss that occurs when drawing from an outlet that does not occur when drawing from the battery. [0] https://www.notebookcheck.net/Our-Test-Criteria.15394.0.html https://www.notebookcheck.net/Our-Test-Criteria.15394.0.html

    There is loss to convert AC/DC, likely low 90s efficiency. Having an in-line DC power meter should be a very simple task, measuring the draw power from the outlet is rather pointless.

Fan noise and short battery duration were my reasons to return my Framework 13 12th Gen. I believed they were related: CPU running on max (without any reason), thus fan spinning high and short battery. On Windows I couldn't find any way to solve this issue, response from support "works as expected". Is there now any way on Windows to limit CPU such that the fan does not need to run?
