I am starting to worry about whether this device will really run the games that these similar tablets run on YouTube
Tablets - especially cheap chinese tablets - don't always have ideal thermal layouts either. I don't expect the heat situation or related performance hit to be much worse, if at all.
Besides increasing the height and adding a fan is there anything else they could have or should have done here?
they could've separated them so one could be on the screen side and the other on the controller side.
That's about the only feasible improvement, heat-wise. Had they stuck the processor/RAM/eMMC on a board behind the display and used an aluminum top cover directly in contact with the SoC, I doubt the chip would ever get hot enough to throttle. You would have roughly 13 square inches of radiative surface, and more thermal mass than should ever be necessary for a 2W chip.
However, this setup has a couple of drawbacks. It would have added thickness to the overall design, as well as weight. Most of that added weight would be in the lid, which would require a more robust hinge or it would start to sag. These factors would both add cost. But the possible dealbreaker is that it very well might transfer heat too
well. Heat is better out than in, but shunting it directly to the case means the case itself gets very hot. Selling a gaming handheld that gets hot enough to burn skin buys you a quick ticket to lawsuit town. Would such a setup get hot enough after prolonged gaming to actually burn you? I don't know. I kind of doubt it, but it's possible. I remember seeing a teardown of an atom-based tablet that did this. The comments stated that the case did get "very warm", but that testing showed no throttling under extended load.
There seems to be a number of holes in the PCB also. As heat rises, the heat therefor should rise from the aluminum & Copper heat sinks through the keyboard PCB and its holes and out through the keyboard cutout.
The speakers helping with heat dissipation, well, maybe a little when they are on.
As long as there is some air flow, there is a chance this might be ok.
Just no. The PCB and keycaps themselves are highly insulative. There will be no appreciable airflow through the case. Their claim that the speakers will somehow help cool the device is laughably wrong on several levels. The few vents will do little to nothing because, as previously stated, there will be no airflow to speak of.
The win is going to handle heat as well as can be expected given the size and layout constraints, but lets not pretend it's ideal. I wouldn't even go so far as to call their heat management steps good
- just less bad
