Yes, aware of the aftermarket aspect fully. Yes a larger fan would achieve that and may be a solution, though a slower spinning fan would equally be good, maybe both. Looking at this cooler, I don't see why for my use can't use it without the fan. Equally I'm ok with some noise, as long as it is not within the range I'm recording and as such, easily filtered out. So whilst a small fan may make a higher noise, it also makes a higher frequency noise, larger fan == lower frequency noise and that may be an issue in the my use case. But early days, be lots of alternatives and choice out there, though looks very promising. Just wasn't aware the RPi4 could be overclocked, so that's kinda a bonus.
