I assume they’re doing it this way because it’s the cheapest.
Correct. This is also why many datacenters are being built in drier climates like eastern Oregon or Arizona- the very dry summers make for very easy evaporative cooling that can keep the cooling loops at below ambient temperature for close to free.
They could use closed loop radiators, but that requires a ton more space and surface area for less efficient cooling, or heat pumps, which will probably increase their energy usage by 30%+.


Be realistic, not many people using apple devices (or any mobile devices tbh) are going to care or be intelligent enough to pull an open source alternative
