Framework Desktop (Ryzen AI Max 385) Heatsink technical drawing

[GuestM]

Hi,

I have HDPLEX H3 Fanless PC Chassis

I would like to mill/create my own heatsink that would cover the same area as the heatsink delivered with the product. I want to use HDPlex heatpipes and connect the heatsink with the chassis… Do you know if there is a technical drawing / CAD of the original Framework heatsink?

My worries are that if I would use just the heatsink that goes with HDPlex, it would leave Framework board without cooling of some additional components…

Thanks in advance for any suggestion/help.

Not yet, but I’m actively working on the same thing which is kind of funny
I documented the Motherboard dimensions that I measured in this thread:

Motherboard photos and dimensions

All the thermal pads seem to be 1.25 mm thick edit: 1.25 might be cutting it a bit close, probably want 1.5mm pads with these measurements, see comment about heights of different chips below Ram Modules: 15x12.5 mm CPU module: 38x45 mm If you wanted to cool the CPU and RAM you’d need a plate approximately: 89x59.5 If you wanted to cool the CPU, RAM, and VRM you’d need a plate approximately 107x 103 (103 could not be measured directly) CPU contact on the cooler seems to be raised up 0.5mm f…

and I’m currently in the mock up stage using my 3d printer:

3rd time’s the charm (technically 4th try, I broke one removing the support/shim for the recessed hexagon (that’s where I’m mounting my cooler, which is a waterblock))

Edit: I still need to do a fit with thermal pads and obviously make one out of aluminum
