Its a bit more than a heat sink that’s needed. Apple’s physical design still won’t allow the heat to dissipate via the fan.

If I was Apple… I would have created a vapor chamber which can be made thin and then mounted with a fin assembly to the side with the fan blowing across pushing the heat out.

If you look you can see there is enough room to put one in. mmm… a possible upgrade kit??? You still would need to tune the thermal management logic within the SMC as Apples thermal curve still would be biased against the improved cooling.

It would most likely be very hard to upgrade the heatsink itself, however a better quality cooling paste and installing a thermal pad between the case and the heatsink would most likely help a bit.

The idea behind the current cooling solution is to push air through the system to cool everything with one fan instead of focusing a lot of cooling capacity on the CPU. If you’re okay with breaking the warranty I’d likely recommend that
