OptiPlex 7070 SFF NVMe Thermal Pad
I added an NVMe to my OptiPlex 7070 SFF. The service guide mentions a thermal pad. I've found the part number G42TT/412-AAPU listed as the proper part number but it's not available for order in the US.
I can get a thermal pad from Amazon but what's the proper one? The ones I see are thin and the one pictured in the service guide is thick and looking at the spacing between the NVMe and motherboard it looks like I need a thick one, but I don't want to get one that's too thick.
Any suggestions?

Be warned there's an automated system that will keep sending message leading you to nowhere. Ignore those messages, they are just a waste of time. I ended up getting directed to the sales team which my post started of saying they were unable to provide me with any assistance.
So, does anyone have a workable solution?

The 2mm and 2.5mm are too thin, I've tried one from Amazon. The 5.25mm looks like it might be about right, but the 20x20 doesn't sound long enough. It would be nice to see a picture of the real one.
I am wondering how well a thick thermal pad would conduct the heat to sink into the motherboard, it would probably be better to add a heatsink on top of the NVMe.

@bra51776, Thank you!
My NVMe is longer but as long as I get the right thickness I should be okay.
Have you looked at the temperatures for the bare card vs. one with the thermal pad, and have you tried a heatsink instead? If so, what were the results?

I bought a 5mm pad and cut out a proper-sized piece. My NVMe temp is about 8C lower with the pad.

Where were you able to find a 5mm thick thermal pad?

The Dell P/N for the NVMe thermal pad in my new OptiPlex 7090 SFF is
It looks like it is 20mm x 20mm x 5mm thick.
