Due to the poor heat dissipation of the original shell, we have redesigned a brand new shell.
The old shell relies on a top mounted fan and a metal casing for heat dissipation; The new casing has added heat sinks at the bottom, and the top mounted fan has become the bottom.

Next, compare the differences between the two casings under IDLE and pressurized conditions.
