Graphene Thermal Pads

Its certainly a lot cheaper
Than the thermal grizzly version

Though its technically not graphene
Its some other material with a layer of
Graphene
Which they advertise as graphene
Which is a bit misleading
Should say graphene coated material
Or something along those lines

Have seen the thermal grizzly one tested
And came out very similar results
As thermal pastes
Though the advantage is no drying out
Over time
No pump out
But it's electrically conductive so need to
Make sure it doesn't move during installation
And the price of the thermal Grizzly one isn't cheap
 
Sry, I am not familar with the exact same product in question.

Unsure about what size I needed, I bought the biggest graphene Thermal Grizzly sheet (incidentally at a discount at a local online store, together with a Ryzen 7000/9000 delidder tool), but haven't used it yet.
Instead I used liquid metal for the cpu cooler (water cooling).
Apparently a trick is to apply a drop of mineral oil, to help prevent the sheet from shifting out of intended position during mounting a cooler.
I've read that, these sheets can be reused, but I've also read that they can be heated to regain some of its original shape. Unknown what the performance is before and after reusing this.

Ah I just remembered. I think it might matter which direction you rotate the graphene pad, unsure, meaning, if the pad is aligned perpendicular to the cpu cooler's heat pipes or not.

I’ve just ordered some PTM7950 pads so will update this thread when I’ve applied it. On the system I’ll be using, I’m currently using TG Duronaut.

Oh yeah, I've got some of that. I've not bothered using it on CPUs though, well not between an IHS and cooler but did use it when I delidded my 8700K between the die and heatspreader as I didn't want to mess around with liquid metal. I think it's also supposed to be good on GPUs.

PTM7950

Does anyone use PTM7950? Is it as good as it seems, is it worth the price? Struggling to find a good place to buy it. I hear you have to be careful that what you're buying is actually PTM7950 and not something more generic. Any tips on how to know I'm buying the genuine article?

One of graphenes biggest perks was it's life span, we need a minimum of 10,000 hours. Regularly see 4,000 hours per year operation. Adhesive based ones were another option but thought that would reduce repairability as our heatsink covers the whole PCB.
I was just very surprised at the performance Vs our usual silicone thermal pads.

Allegedly the Thermal Grizzly PhaseSheet is rebranded PTM7950. Agree a different thing to graphene pads which tend to be graphene-coated copper foil.

You need some type of substrate/structure for graphene to adhere to or it becomes carbon.

Its already carbon
If you made about 10 layers
Then it's basically going to become graphite

As I already said
Its somewhat misleading to market it as
Graphene rather than another material
With a layer/few layers of graphene

The graphene has to remain in its shared state or it will reform back the base carbon be that graphite, charcoal or whatever, hence the need for some kind of engineered structure, but it’s still graphene.
