So I couldn't get a definitive answer on thermal pads for the FTW3 so I took a punt and bought an assortment of Primochill stuff to replace the memory and VRM pads on my FTW3 ultra and thought i'd share what I learned.
 
Firstly, the memory needs 2mm thermal pads. The best info I could find suggested 1mm pads and I ended up needing to double them up on the memory. I actually ended up running out of pads because of this which led to me not quite getting full coverage on my VRM's
 
VRM's need 1mm thermal pads. I can see why they used thermal putty after pulling it apart because they are not uniform height, their height varies quite a bit which is what the thermal putty works well with.
 
The backplate needs 3mm pads if you want to get some contact on the back of the memory, that gap is quite large.
 
Now before everyone flips out at the amount of thermal paste in my photo, I took it before I had scraped it off to a thinner layer. Thermal performance after re-fitting the cooler with the thermal pads and fresh paste is basically the same, GPU2 temperature is slightly improved and I have managed to squeeze an extra 25MHz core out of Timespy on ambient air cooling, so it looks like I have managed to derive some slight benefit from it.
 
The OEM thermal paste was nowhere near as dry and crusty as the Gamers Nexus one was in their teardown. The thermal paste on my card was evenly applied, not too dry and cleaned off very easily.

Did you consider using liquid metal?

How come you missed the most important comparison here
 
Stock Thermal pads vs Aftermarket Temps
 
You mentioned gpu2 ( backside) now cools better but how much ?
 
Also how about gpu core and mems ? I guess EVGA already used quality materials on pads.

Would the 3080 be the same thicknesses?

They are basically the same card so I would think they would be

stacking the thermal pads, will impact thermal transfer ... but, sometimes you have to work with what you have in supplies

where did you source your 3mm pads for the backplate? did you have a shot of where you applied them?

He made a similar post on another forum, I don't think he actually did them all, and I would guess based on the brand of thermal pad he bought he just stacked a couple 1.5mm pads on top of each other.

Thermals are essentially the same across the board. No real measurable difference in temperatures, however I have gained the extra 25MHz so it has maybe done something. If I didn't have to double up on some of the pads then my result would probably have been better.

Re: FTW3 Ultra 3080 Thermal Pad Thickness 2020/10/23 08:32:39 (permalink)
Would it be okay if I just took apart my 3080 and replace the thermal putty with 1mm thermal pads while saving the existing thermal pads already placed?
I would also add the 3mm pads on the back to allow backplate contact like you suggested
 
Ive taken apart multiple cards/laptops and never actually come across thermal putty & id ideally want clean even coverage when putting it back together after I swap the TIM with Kyronaut.
 
Never seen these on my EVGA 2070S 2060S 1070s etc.
 
On another note Fujipoly seems like the best on the market atm however its rated at 11.0W/mK which seems like overkill along with a higher price.
Im thinking the Wathai brand with a 1.5W/mK since VRMs wouldn't produce that much heat unless you think otherwise. Thoughts?
Wathai sells all 1/1.5/2/3mm pads on Amazon

Does anyone know what the thermal conductivity specs are for the pads and putty used by EVGA on the 3090 FTW3 Ultras? I wanted to replace mine but I wanted to make sure i meet or exceed the technical specs for the material I select. So far I am considering Fujipoly Premium with a thermal Conductivity 6.0 W/mK. I was thinking the Ultra with 17.0 W/mK maybe overkill, or will the memory chips need the higher spec pads?
