While the main cooling system is important, the thermal interface material they pick is also a big deal with systems intended to not be user serviced and with long lasting lifetimes like consoles… It honestly depends a lot on what TIM they decided to go with. Traditional thermal pastes are cheap but almost always dry out after just a few years causing much higher temps. Liquid metal is great, but more expensive and you must design it right, vertical orientation can cause leakage if not properly designed (some laptops end up having issues because of this). Phase change material is probably the optimal middle ground for ease of installation, and simplified design.
