CPU and GPU still dump heat in the same chamber, so it’s probably not gonna do anything special.

Fatter, dual chamber cases, with the PSU and drive cages behind the motherboard already have proper bottom intake, that’s not blocked by anything like the PSU (shroud), so this case is not doing anything new.

As long as the gap between the two chambers is big enough, so air isn’t hindered, it’s probably gonna be fine, but mostly a gimmick.
