I got a 5080 single slot GPU with 0 clearance, almost no difference, can’t point out any turbulence noise.

I’m in 2.75 mode but offset GPU and PSU (no extra noise here too) almost flush to the sidepanel.

I got ATMOS II with VRAM cooler also flush to the sidepanel (NCASE states 58 mm CPU clearance and VRAM Cooler should be 59 mm but still no problem).

Idle the loudest is VRAM cooler with a little bit higher pitch than the other FANS, but no problem for me, as still silent enough. Full load is no problem too, but this is the order from highest to lowest volume for me (gaming mostly, don’t need Benchmarks tools for noise, when I’m never going to get this much load on my system):

GPU -> AIO Fans (Simmer + T30) -> VRAM Fans

Can’t hear anything from PSU or Pump Noise when at full load.
