@variablepulserate Yeah, looking at the PCB and general layout of the 2020 MacBook Air internals, it makes one wonder. It's kind of going the MacBook (2015 - 2019) route with passively cooled logic board, only to slap on a fan without any real efficient purpose on the side. It's like two different people designed the whole layout, only they weren't allowed to talk to each other during the process.
Most puzzling.
I can see a good amount of space where a heat pipe could be fitted to a small heatsink right at the mouth of the fan, exactly like in my old 2015 MacBook Air. At least this fan actually does a difference.
