| Especially if with the radiators you can just roll out as rolls of aluminum foil, which is very light and very cheap. |

| Only on a short distance. To effectively radiate a significant amount of heat, you need to actually deliver the heat to the distant parts of the radiator first. That normally requires active pumping which needs extra energy. So now you need to unfold sonar panels + aluminium + pipes (+ maybe extra pumps) |

Dispersing the GPUs might be more practical, but it's not exactly optimal for high performance computation... | | |
