My WC Genie has fairly unusual airflow. When I WCed it, the Seasonic Super Silencer (single 80mm) started ramping its fan thanks to the warm intake air. To fix this, I divided the top and bottom sections of the case and removed the 92mm case fan in the top section. Now the lower half has a 120 pulling air through the intake, HC, and across the mobo. In the top, the HD exhaust hole is now an intake for the HD and PSU. Works well.
I recently swapped the PSU fan to an L1A, which helped noise and (apparently) provides adequate cooling.
