Also should I use 2 fans at the front of 140mm, or 3 of 120mm? I was told with 3 its better airflow.
I will not do any OC. I will be making music, editing video and gaming. I dont consider Aira64 and Prime95 as realistic real life use cases so I dont consider the high temps achieved by those benchmarks as a problem in terms of not having AIO with the 3950x so I went the Noctua 15 route. I just want to improve the case airflow because I was told the Define R6 is a solid case but the stock fans are rather crap.
Go for phanteks enthoo pro M if you want 5.25 bay.
If you want silence, you want a case that impedes airflow as little as possible, the minimum number of fans and speed to get good airflow and manually tune their rpm curves.
Also, choose a GPU model with a good radiator.
In the case of a ryzen you want to manually tune the frecuency and voltage, and/or tune up the RPM on the cooler fans, one, because of its boost, and 2 because of its thermal density. You don't want the cooler ramp up and down everytime you load a website.
For example, something like this:
Phanteks enthoo pro M
3x120mm sw3 mounted on the front and the case fan mounted in the rear
And then treat the front fans as a group and use same speed on all of them, and the rear fan make it ramp up a bit later.
For example 0-35°C 400 RPM on all fans and cooler, 55°C 700rpm for front fans and cooler, 65°C 1000rpm front fans and cooler, 700rpm rear. Next point should be set up considering your preference and tolerances.
That should keep your PC almost dead at low loads, and very manageable under heavy loads.
For even better results, you can still add another level of configuration/difficulty. Manually tune up the CPU, and after you find the point where "it hits the wall", drop 150mhz, and as much voltage as you can, then set up the fans accordingly. You should be able to drop a ton of voltage, and thus temps/noise. GPU can be modded with case fans attached with zipties like in the picture, and the improvement in noise is awesome.
