The single thick copper heatpipe from the newer FW13s seems pretty good, and I’ve been thinking about upgrading my current amd 7040 series motherboard with it. (I use some engineering software that heats up the thing a lot. ) However, due to the chipset distribution around the core I don’t think if any of the two new heatsinks currently listed will be compatible.
Some workaround can be devised if I can find the dimentions for the heatsinks and see if some padding can make it work, but for now I am thinking about welding my 7040 fitting plates to the new heatpipe, so waiting for the new heatsinks to become available.
Does anyone have like a 3D design file or somesuch about the processor & chipset dimentions / thermal interface?

Repasting PTM7950 may work. The bottleneck is thermal interface as the CPU heats up to 90°C within a second at pulse load, instead of gradually heats up over several minutes to overheat and throttling at sustained load. I got 10°C reduction is CPU temperature at full load. The newer heat sink covers the VRMs however VRMs overheating in 7040 is much less common

I have considered this upgrade too, but I am not sure if this would make a huge difference.
I did a comparison of the product pictures here, looks like it could work.
The stock heatsink with ptm or lm is already pretty good but I wonder how much better the single heatpipe cooler is.
