I wished they would measure the noise of the fans as this sounds wonderful, yet without knowing now noisy the fan is, would kinda negate many use cases I'm looking at (audio recording). I also would like to see this setup with the fan not active as that heatsink and the margins of cooling it has, it could be enough for many use cases. OK found a video that does a more indepth review of this cooler and sound. https://www.youtube.com/watch?v=tie6r5ymUug https://www.youtube.com/watch?v=tie6r5ymUug

Do you really need to OC for audio recording? That sounds like something a less capable machine could do, but I'm fairly ignorant of the CPU requirements of audio recording.

  Using external sound system that runs via USB into Pi, works well. Looking at additional processing and with that the rPi4 would be choice, though heat issues may need addressing by all accounts and this looks like it will cut the mustard. Sure the processing I'm doing, I could batch, but real-time makes like so much better in the instance I'm using it for.

>without knowing now noisy the fan is That is completely up to you to decide. IIRC Raspi4 does not come with a fan so you need an aftermarket one. There are plenty of silent fans. It gets easier if you can increase the size, because bigger fan blades can be turned slower for the same airflow at reduced noise levels.

  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.
