I have to say beforehand that I actually wanted the Fractal North, but it wasn't available at the time ; ) That case was the closest I got. But yes, the airflow is pretty good. The fans in the front draw air well, the plate to the right of the mainboard directs it directly into the CPU cooler...

... over the mainboard and to the graphics card. In addition, the whole case is very open at the top and rear due to the perforation. Even with little pressure from the fans, the hot air flows out easily. At idle, the fans rotate at just 500 to 600 RPM and the CPU does not exceed 40 degrees.
