4,510
Case: NZXT H510
MB: Gigabyte Aorus Elite X570 (has a pretty big VRM heatsink)
Top fan: Noctua Chromax 140mm

Since the H510 case isn't that big, the MB fills up most of the case, and the VRM heatsink sits very close to the top exhaust.

The thing is, part of the 140mm top fan hides behind the MB heatsink, whereas a 120mm fan would not.

Do you think this would interfere with the airflow of the top fan? Would a fully exposed 120mm fan be better than a very slightly partially hidden 140mm fan?
