I mean physical tunnels from the front or side of the case directed at the cooler heatsink to direct outside air directly onto the heatsink. There were tons of different designs for that concept back in the day, but you don’t really see it very often now.
There were a lot of experiments with wind tunnels and such back in the day. In the end, the difference wasn’t significant enough to justify the R&D.
??? You don’t wind tunnel test for thermals. That’s for aerodynamics. It’s well known that a GPU outside of a case runs cooler than inside.
It’s why cases are tested by putting a GPU inside and reporting the thermals at idle and load. It is significant.

Maybe they didn’t mean wind tunnel, but that they lit a cigarette and checked the airflow 🤷
