With bottom and front intake and exhaust in the back, cool and hot air mixing shouldn't be a problem
Ofc you find the very best results by testing. I would do what i suggested, run some benchmarks and check temps, then turn the back fan around and run some benchmarks again.
I will say it again:We do not want a wind tunnel. A wind tunnel is uncontrolled air blowing through the tunnel / case. We want to control the airflow by flowing the heated component exhaust out of the case without it mixing with the cool intake air going to components
This has to be done without having huge positive pressure
. We want a nice quiet flow of cool air to components and their heated air to quietly leave the case without mixing with the cool intake air. It's all about guiding the air where we want it to go, not about making a wind tunnel.
My sig rig has no exhaust fans with 3x TY-140/147 intakes, PCI slot covers removed and back grill removed, and no exhaust fans.
Case fans idle at 750rpm and full load 1100rpm. Air temperature inside of case are never more than 2-3c max above ambient. CPU at 97-100% for extended periods is always below 50c, usually 23-47c. GPU never goes above 55-60c, usually 30-44c.
