This layout results in an estimated 231.68CFM intake and 225CFM exhaust for a net 2.97% positive airflow, enough to bias toward positive for concentrated dust collection yet not so much it inhibits airflow.
With this build, I average 20c above ambient at idle and 55c above ambient under a Cinebench r23 multicore load. My fan curve is manually tuned to linearly target 85c as the 100% RPM point with 25% RPM at 50c and 20% at 30c.
