"textContent": "What is the current thinking on using say 140mm to 120mm adapters or purpose designed hoods to increase SAP (Static Air Pressure) and give a more strongly directional airflow over the MB?\n\nI ask because both the cases I have (Fractal) for new builds have positions for a side mounted intake or exhaust fan (I know there is controversy around that matter too) which will sit, roughly, opposite the NVME drive location on the MB. I was wondering if a more directional flow of air from a hooded fan might be beneficial.",
