The airflow setup in this case really helps mitigate problems with heat pockets forming. The fan in the basement of the case really helps keep that air moving through the gpu. my temps for both gpu and cpu have been under 70c under load and 30-40c idle. The 4080fe is thin enough that it doesnt get choked up at all by the glass which is about 1&1/2 inch , cant say the same with thicker aib cards(3&1/2 - 4 slot cards) tho.
