The cooling fins are a type of heat dissipation component attached near the spine, replacing the skin.
Lille's cooling fins weren't particularly large, but they were definitely high-end modifications.
The entire component covered the upper back thorax, roughly near the scapulae.
When activated, it would reveal its full form, standing upright like a dinosaur's dorsal fin, with cooling fluid flowing through the inner parts, following a path closely adhering to the prosthetic spine and up to the brainstem through bioplastic tubes nearly the same size as capillaries.
The heat from these prosthetics was transferred to the cooling fins and dispersed with the wind—
In extreme cases, you could directly replace the cooling fins to achieve a heat exchange effect.
And those two external mechanical arms… to be honest, Lille felt that the mechanical arm structures in the Cyberpunk World were indeed outdated.
