Its to compensate for apples innovative cooling design. Ive desoldered the old heatpipe from the heatsink and soldered a new one on that i press against the main heatpipe.
Sorry it isn’t quite clear to me, is that additional fan adding to the existing cpu cooling solution because you saw overheating or to get the most thermal performance?
Yes its adding to the existing cpu cooling. The first prototype of this I build was using an i5 1135 cpu and was getting pretty hot. So I figured adding an additional heatsink and fan would help. On the Ryzen board im not sure I would have gone through that trouble again, its running much cooler.

This is excellent! Curiously wondering if a smaller Macbook Pro would have been also a worthy candidate? Or would the space provided there just not be sufficient?
Excellent work!

If you dont add a second cooling fan I dont think that would be an issue on the 15 inch. The 13 might be difficult to fit the battery but I think it would be possible.

I had to take it apart to replace the edp cable so I took a couple more pictures (without the tape).

Damn, that’s impressive.
It was already, but seeing the back with the second heat pipe attached gives the sense that almost nothing could stop you.
The perfect Macbook

did you made from scratch the io and keyboard boards? impressive!
The Io boards yes, the keyboard controller is a modified version of apples design using the keyboard chip from the MacBooks mainboard.

This is seriously cool!
what’s going on with the battery? It looks like you just peeled the sticker off the Framework 13’s battery and stuck it on top of the MacBook one.
no? theres another sticker on top of the framework battery
also you can’t peel off the fw battery sticker its printed onto the batterys casing
Great work, any plans on sharing the designs for others to tinker with?
I’ve hollowed out the original battery and put two framework batteries stacked on top of each other in there. Just put the sticker back for extra isolation.

No, I will not. Too much potential for headache when I do.
That keyboard adapter sounds intriguing – is it easy to reverse engineer and did you need a dead rMBP to harvest the chip from?
K3n.
Its not difficult to build but it takes some time. And yes you will need a Macbook for this. The main IC is an off the shelf part but I would not know where to get the program on it from. For the most part you can just copy the schematics from apple and pull necessary lanes to ground and vcc. But if you want do do this make sure to copy the schematic for the exact model of macbook you take the IC from, they dont all have the same pinout.
If you knew the pinout which presumably you do then you could just program a microcontroller to translate the signals and send them over ordinary USB.
This is incredibly cool. Huge respect for making those custom conversion PCBs, that’s incredible.
How is daily usage on a modern OS with the trackpad?
