Something also to note, that there was a thermal unit fix during production validation, so mass production will probably do a better job, overall, of transferring heat out to the fans. However, all systems face the issue of fan noise when under high load. No other way around it, need to move air to get rid of heat. From what I’ve seen elsewhere, the max noise is in-line with other 16" ‘gaming’ systems when fully loaded playing a game.
They also have a chart at different loads, off, idle, average, and playing games and fully loaded. Framework is also one of the best (lowest) at fan noise when it comes to average load.
General usage will be a LOT quieter. https://www.notebookcheck.net/Radeon-RX-7700S-performance-debut-Framework-Laptop-16-review.790807.0.html has some measurements:
Fan noise covers both extremes quite well in the sense that it can be very quiet when running undemanding loads and very loud when running more demanding loads like games. When simply browsing or video streaming, for example, fan noise would tend to hover around 28.5 dB(A) against a silent background of 23.8 dB(A) to be mostly inaudible. When running Witcher 3, however, fan noise can reach almost 52 dB(A) to be as loud as the competing Inspiron 16 Plus or some gaming laptops like the Razer Blade 16.
