Ive been playing around with fan profiles today, the bottom 3 fans now run at 700rpm, but there silent. rear fan at 600rpm and the 2 for the aio sit at 500rpm with pump speed at 1750rpm. No issues temp wise, cpu hits 41-44 under things like cinebench, idles at 25c and hits 39ish while gaming.
the only thing in the system that makes any noticeable noise is my HDD and the gpu fans while gaming, they hit 1300rpm at 60c and stay there, gpu itself has never gone above 70c but often sits around the mid 60s.
It took me a while to decide on a case but glad I picked this one up, air flow was a concern but its much better than I expected.
