Just curious... is the nvme heat spreader in the Elite Mini g9 graphene?

[foxyrick]

Inside the Mini G9 are two slots for nvme. They have a nice thermal padding material underneath the nvme, and a paper thin, floppy cover that sticks over the top of the nvme. It looks like it is coated in a black finish.

I'm just curious if that is a graphene radiator. Would be nice if it is, I can't see such a thin thing being much use if it isn't.

Anyone know for sure?

@foxyrick,

Welcome to our HP User Forum!

The black padding you are referring to is definitely not graphene, as graphene has a high electrical conductivity, which would fry your M.2 NVMe SSD.  The padding is intended to protect the M.2 NVMe SSD given its very close proximity to other PC components, and just like a thermal pad, is heat conductive whilst not electrically conductive.

Hope this helped.

Kind Regards,

Just so you know, currently Graphene is one atom thick.

You are probably correct, although I did find that HP are using graphene thermal pads in their own M.2 SSDs:

Great catch. I certainly had not seen that.  In that case it is possible that it could be graphene.

Check the part number and research the manufacturer's specifications.

Had you already done that and it resulted on your find?

[foxyrick]

Yes, I already searched a lot. That link (and a couple of reposts about it) was all I could find.

I'm about to take the lid off again and fire up my HP bench meter... see if the top, black layer is conductive.

@foxyrick,

Interesting, but again, it looks that the graphene layer is not directly applied to an M.2 NVMe SSD:

The graphene/metal heatsink would still be separated with a non-electrically conductive heat pad, such as illustrated here:

It's certainly not graphene. Looking at it again, it's not even similar to a graphene/polymer film. So much for my memory, lol. That's what I get for doing jobs at 3am in a dimly lit room.

Thank you all for the replies.
