CM4 heatsink application

Hey All

I’ve recently purchased a CM4 adapter for my DevTerm.

Is the copper/graphene sheet supposed to be sticky on one side? I’m guessing the graphene side as that faces outwards. Mine is not. I don’t want to leave a big sheet of copper facing the internals without being stuck down for obvious reasons. Wondering if this is just my set of if I’m missing something/doing something stupid.


yeah that’s exactly how it is… the only thing sticky is the thermal pad.
make sure copper won’t touch anything sensitive before you power up!

Sorry for the slow reply.

Thanks for the info. I’ll probably give that a miss, way too risky to have loose copper flapping about in the case.

Just stuck it to the back panel with spray adhesive, its somehow working better than the stock aluminium one despite feeling like carbon copy paper
