Using this build for gaming and media creation. Nearly everything worked well when installed, except the Seagate Barracude HDD which I wasn't able to format at all and was always on fullspeed making the build itself pretty loud with the vibrations.
Decided to get the HDD out for now and just use the m.2 Samsung 970 Evo which I didn't have any problems installing.
Using the Noctua Fans as Push Configuration on the EVGA CLC 280 served to be really effective.
I was able to boot up the pc with 3400Mhz, with normal 14-14-14-34 Timings on the G.Skill Trident Z RGB Kit but unfortunately it seemed a bit unstable when playing games and doing benchmarks so I reset it to 3200Mhz.
All in all I am quite happy with the build itself, after having a FX8350 paired with a AMD 290X.
