How It Works
Every case is a tradeoff. We didn't think it had to be.
The Engineering, Step by Step
How a CoolCase actually gets designed, from heat map to finished shell.
-
Map the heat path
Before we cut a single channel, we mapped how heat actually spreads across a phone's back panel during charging and heavy use — the hottest zones aren't random, they cluster around the processor and battery.
-
Cut airflow along it
The channel pattern follows that heat map, not a generic decorative grid. Openings sit exactly where heat concentrates, so air can carry it away from the zones that matter most.
-
Choose the shell for conductivity
The shell material is selected for how well it moves heat through itself, not just for grip or looks. It works with the channels instead of sealing heat back in like standard silicone or TPU.
