Thanks, would you mind linking to the fans you’d recommend?

These would be the standard swap:

A lot of guys are going to the 140mm and using a 3D printed adapter plate to fasten them:

140mm = better airflow?
It’s a combo of it running quiet and best - since these Noctua ‘quiet’ fans generally max out at 3000rpm’s (compared to stock 6000rpm max), the 140mm version just does better in cooling/airflow vs. the 120mm version.
120 would work and you wouldn’t need an adapter. The 140 needs a printed adapter.
I think I want to go for the 140mm then, just need to find someone that can print it for me. Or maybe I should finally buy myself a 3d printer and print it myself...
