If you can design your airflow to go from front to the back and from side to the top that will make cold air come in while same time as hot one gets out. Maybe even make more exhaust fans like 2 intakes 3 exhaust to created low air pressure inside the case so cold air will come even faster. Point is, whats better, a steam of cold air right onto your mobo chipset or a fan that just took hot air from your CPU and another fan sent it right back to chipset. Moreover 12 fans without dustfilters will make your PC sound like a jetplane in about 6 month, not to mention mess inside the case.
Your point of having the fans placed that way is correct, they shouldn't be placed at random places in random directions.
However, that doesn't mean turbulence is bad. You can have the front fan blow air in, have a side fan to create turbulence on your hardware, and the exhaust fan to draw the air out. When I still had my Stacker 830, I used 2 front intakes, 4 side intakes to blow directly into the motherboard and graphics card and 3 outtakes. (including PSU)

Well, the only thing a fan does is move air around. All you need is a proper dB/CFM ratio.
