I'm trying to get my PC as quiet as possible and I'm to the point where the only noise is fan noise (and I don't have many fans): * Arctic Cooling Accelero Extreme III cooler on my 1080 Ti - this seems to be the noisiest component - I think I'm hearing bearing noise and I noticed tons of very tiny droplets of oil/lube on the window inside my case radiating from this cooler - I think the 3 fans on this thing threw their lube and now have a slight growl. * Noctua: 200mm intake, 150mm HSF fan (DH-15s), 120mm exhaust - these fans are all very quiet and I'm using PWN fan curves to keep them as low as possible. As quiet as my PC is, my Thermaltake V21 case is very open and does nothing to reduce noise and I'm trying to cross over from very quiet to almost inaudible. I want a case that offers good airflow and as much sound reduction as possible. 1. First choice is the Thermaltake Suppressor F31 or F51 case - the problem is that I can't find the non windowed version for sale anywhere - just the tempered glass edition. + lets me reuse my Noctua 200mm fan + no PSU shroud means better air flow for my fanless PSU + solid panel version has side fan mount which my GPU likes - filtration does not seem as good as fractal 2. Second choice is the Fractal Design Define R6 - I'd prefer the gun metal version, but again, this color does not seem to be easily available with a solid panel. + best looking + USB-C option - shroud and PSU airflow not ideal Can anyone who uses these cases speak to the sound dampening difference of the solid panels vs the TG panels? TG looks nice, but it seems like it's just going to resonate/transmit too much sound but maybe I'm wrong.
