Hahaha!
I’m thinking of designing a control system that can monitor differential pressures inside and outside of the case, then interface that data with the BIOS to control fans using an algorithm that balances the thermistor outputs with the barometric delta.
Think it’ll sell? 
I was about to start my previous reply with…“if only there were a gauge or a system properly measuring the pressure inside the case…”, but thought I’d probably open a can of worms, decided to stick with the conventional pressure measuring “methods” 
I bet it will!
Cheers, can’t wait to test it all out. Congrats on a bargain steal 
I like this guy’s explanation and test visualizations.
