Description
Tier 3 Synthesis Material
Lore
Heat dissipation is a challenge that all Intellitrons must overcome. Although Intellitrons created using different generations of technology differ significantly in terms of materials and internal structures, traditional physical heat dissipation often remains the most suitable choice for many models. "It's just like organic beings bathing in water."
