Earlier quoted context omitted.
Do you use it as a gaming PC (or for other high GPU load activities)? And if so, what's your take on noise under load? Edit: I guess this is a senseless question if the case really only uses passive cooling. I was assuming there would still be fans somewhere. I despise my current PC's fan noise and I'm always on the lookout for a quieter solution.
Did you have no success upgrading your fans (Noctua etc)? Still too loud? How about water cooling?
Now my CPU idles at ~35 usually, which is just 5 degrees above the ambient temperature (because of summer...), and hardly ever goes above 70 even under load, and still super quiet. Realize now I should have done the upgrade years ago.
Now if I could only get water cooling for the radiator/GPU I'm using. Unfortunately no water blocks available for it (yet) but can't wait to change that too, should have a huge impact as well.
