Hi 2disbetter, the placement of the battery worried me too, so I put a 1mm thick layer of insulation material between (in my case compressed cardboard) and I put it under 1hr stress test and then measured the temperature on the bottom surface of the battery and it was 40 degrees celsius on the hottest spots (which were, curiously, on the place where SSD is, not the heatpipe, as there is an air layer between the heatpipe and the battery but SSD comes in direct contact and I use a gen4 one without any cooling). Still, 50 degrees celsius are still within spec so I believe I have a bit of headroom there.
As for the cooling, it can handle 28-32W which is in line with the laptop performance. Battery does cover 90% of the fan on the top side, but the main air intake is from the bottom anyway. It reduces the max cooling capacity by 2-4W as I have never seen the board exceed 35W even if completely out of the case. That 10% of uncovered fan on top side is useful when you put the tablet on a bed. It can still somewhat breathe.
I am sorry that the project takes so long, I ran out of personal time for several weeks multiple times during the project. All files that I created can be made available for anyone, I just did not feel like publishing them when I still use duct tape to hold some pieces together.
Current phase is that after about two weeks of daily driving it I found out that my case needs to be a lot stronger, so I am adding multiple reinforcements to it and also that display requires a much better mounting system, so I have to adjust the current one. If you like, I can send you or post here or somewhere all files that I have had, also of previous concepts that would have worked with battery in a traditional position, but they have never been printed. But it would be an alfa version at this point, while beta is in making.
*I should clarify that framework 11gen mainboard by design cannot sustain more than 28W TDP turbo boost for more than 30-40 seconds in line with intel’s stock turbo behavior and it cannot be altered neither using XTU nor throttlestop, even FW support confirmed that it is not possible, that’s why I am comfortable with cooling that can sustain 28W.
** Also I bear no responsibility in any premature battery wear, if you follow my work it is voluntary and at your own risk, I measured it several times but you might want to do your own measurements as your insulation material may vary
