Read the explanation

Inside custom 3D-printed eGPU shrouds, cooling performance depends directly on mesh porosity and convective heat transfer from the heatsink. Restricted vent open area produces aerodynamic backpressure. As airflow drops, convective resistance increases, pushing thermal equilibrium higher. Selecting the Optimized Mesh Mod expands porosity to fifty-five percent, restoring exhaust to forty-four CFM and stabilizing core temperatures safely below throttle limits.
