Awarding the best gaming smartphone award to two phones that do literally nothing to be better at gaming over the competition is silly.
The ROG phone doesn't have a "heat pipe". If you look at a teardown (which are surprisingly hard to find for this phone!), there is a plate over the SoC that uses thermal paste to connect to a small copper plate on the shell. That's it. The piece of copper isn't even a heatsink, it's a completely flat plate of copper roughly the size of a penny. Maybe it's a tiny vapor chamber, but that's certainly not a heat pipe! On a proper heatsink and heatpipe set up, the heat pipes are literal *pipes* that use their length to carry heat away from the SoC and spread it across a massive surface area of a heatsink. This has neither surface area of a heatsink nor length of heatpipes to move the heat away from the SoC, and everything is just right there on top of the SoC. The fan accessory then blows on this flat penny sized piece of copper, and that's the only cooling it has. There is no thermal connectivity with the bulk of the phone's body at all, since the phone's glass back is entirely separate and not thermally bonded to the SoC, so it's only thermal transfer point is that flat piece of copper. Which makes the accessory that blows on the back of the phone a little silly.
Looking into it, this thermal setup is far worse than I thought it would be. The old way of doing this, which is an SoC thermally bonded with an aluminium back, would perform far better than this setup. Especially if combined with a third party fan grip accessory, which have always existed.
