Estimates for the modelled airflow. They exclude dust, thermal paste, ambient swings, PSU/pump noise and fan-curve differences.

Build
Radiator placement (AIO only)
v56 (flag ENABLE_AIO_RADIATOR_MODEL_V56): AIO radiator occupies its mount's fan slots, breathes case or ambient air depending on direction, and warms GPU/case intake when mounted front/side. Hidden for non-AIO coolers.
GPU mount (experimental)
v50 (flag ENABLE_VERTICAL_GPU_MODEL, default off): vertical mount with tight glass clearance starves the GPU intake side; effect scales with clearance.
Thermal inputs
Fan layout
Front intake
Rear exhaust
Top fans size
Applies to all top fans (front / middle / rear).
Top front
Top middle
v50: enables a 3×120 top layout (top front + middle + rear), modelled separately from 2×top.
Top rear
Bottom intake
Side fan wall
v40.2: side intake feeds GPU zones efficiently; side fans use square wall geometry.
