I've done a lot of cooler testing over the years and found trying to test and get accurate comparisons of cooler to cooler inside of a case to be very problematic to put it mildly.
If you do cooler testing what do you need me for? Read your own and marvel at how incredible they are.
Saying 'we are using a case system so our testing is real world ' is a joke.
I could put it in a tupperware container in the attic, would that be more like the systems our readers are using?
I've been an HVAC technician for 16 years, it is impossible to maintain a constant temperature to a tenth of a degree (or even 1 degree for that matter) without doing an EXACT heat load calculation for the space you're trying to cool (computer, measurement tools, lights, people, etc. etc. etc.) then designing a system with that EXACT cooling capacity, allowing it to run without ever needing to shut down, as the heat removed will be the same as the heat produced.
