Some updates,....
I ended up use a 0.5 mm strip, a 1.0 mm strip and a 1.5 mm strip of thermal padding.
The ssd controller to the copper thermal sink (1mm) used the 0.5 mm thermal pad, the ssd storage to the Cu heat sink used the 1.0 mm thermal pad. Then the Cu heat sink to the metal chasis used the 1.5mm thermal pad.
My SSD temp is 37.9 C on idle and under load it only gets up to 43-47 C.
It worked out REAL well.
As for the thermal pads I used GELID's 15 WMK, there were other thermal pads rated at 18 (Fujipoly etc) but the cost was 3x and really for an ssd using the chassis as the heat sink I do not think it was worth the cash.
In total it cost me about 50$ for the materials, the installation was without issue and I am REALLY happy with the results. Previously it would hit 70+C on full load and then go into thermal throttling, I have not come CLOSE to those temps, it has never broken 50C.
FYI links to materials: NB: I did not buy the materials on Amazon I am using Amazon links as references for others only.

You can try with the stock thermal pads that the Cu heat sink comes with, I figured that since I had no idea what the material really was it was better to spend the few bucks to get known values for the thermal pads.
I hope this helps others.
Copy that - I learned something new! Those thin metal laptop heatsinks may work then. https://www.amazon.com/gp/aw/d/B07YC1HTFR?psc=1&ref=ppx_pop_mob_b_asin_title
I added a 1tb Samsung 980, and used this heatsink:

Fit fine, the rubber bands were a bit of a pain in the ass to get on lol but not difficult, seems to keep the drive pretty cool
I got these and they worked great.

If you're not doing heavy loads of video editing or large, consistent, file transfers, honestly damn near anything will work great.
You want a few things:
Something like this. These are heat spreaders but they call them heatsinks. Only need 1.5 mm clearance to install.
I got the same one and put these "https://www.amazon.com/dp/B07YC1HTFR?psc=1&ref=ppx_yo2_dt_b_product_details" on it and the Hynix Drive. All my steam, oculus, ubisoft, and EA games are running like a champ!!!

I believe the 2nd slot is gen 3. Make sure to get a heatsink for it.
If you installed 2 HDDs you would be replacing the main one so you'd have to reinstall. I think you could potentially image your old one though? I haven't done that so I'm not sure.
They said a while back they didn't have plans to release the 3070 one in the US. Not sure why.
Here is the kit I used:

I got one of these kits. It came with a couple pads and copper heat sinks (and some loops to hold everything together tight. Put the pad between the drive and heatsink so there was no metal touching metal.
