If the big consideration is really sound, doing whatever is necessary to use larger, but slower (wide, high CFM per dB/RPM) and higher quality (fluid dynamic bearings) fans might serve the purpose regardless of other hardware. Some of them are rated to be <20dB, quieter than a whisper, and fluid bearings are supposed to be mostly impervious to the noise added by aging that hits a lot of fans.


Pick something that interests you but is made by a small, indie, maybe even solo dev. Check out some of the stuff made by people on lemmy in the Godot community maybe. Lots of cool projects to consider.
