Config:

CPU: r9 7900 non x

GPU: 7900xtx Sapphire Pulse

RAM: 32GB of FlareX5, 5600mhz cl30

MB: MSI b650i edge wifi

PSU: sf750

Case: Dan a4H20 (used to be Fractal Terra)

Cooling: EK Nucleus 240 (used to be NH-L12S)

Storage: 2x 250gb 970Evo + 2tb 870Evo

Prelude​

I used to run Terra with a couple of fans and NH-L12S, temps were fine tbh. But the sound, let's just say Terra larps as Boeing 747 with two slim Noctuas and NH-L12S. So a strategical decision was made to swap to an AIO, since Terra doesn't support anything other than a 120 AIO with a small GPU, swap the case too. So the final result:​

Since AIO allows for more thermal headroom I decided to, let's say, optimize)​

!All tests were run in Armenian summer, so take the temps with a grain of salt!​

!I use Cinebench R23 as a reference, which is also questionable methodology!​
