Just made an account to post here. Digikey has all those pad sizes and more.

Laird Technologies makes some graphite pads that sound similar to what you described with the OG pads. A bit pricey though.

A18330-09 is the manufacturer product number for the 2.25mm on the digikey website (digikey PN 926-A18330-09-ND)

The datasheet on Laird's site looks promising too.

There are reports that laird is the company that makes the stock ones. The thing to look for is a low shore number.

Glad I found this thread.  I went thru your ordeal attempting to re-pad an MSI RTX 3090.  No love in that matter.

So now I have an EVGA 3090 FTW3 Ultra, I love it, and it's a stable card with excellent temps.  I ran across these Noctua 40mm 5,000 RPM fans...love them, they even brought temps down 2 celsius.  
 

Great info here. Used a couple of these suggestions on my 3080 ftw3 and have seen decent reduction in temps across the mem junction (~10c) and modules.

I received some replacement pads from EVGA for the 3090 hybrid kit they are branded Ziitek on the removable plastic they ship in.

how can i get them from evga too ? i need 2.25mm pads for my thermal kit . 

How do you see your mosfet temps?

I'm getting mixed messages regarding the appropriate sized pad for where the putty is applied. I've read that the area is unevenly leveled?

I emailed EVGA support because the 3090 I received on a RMA was a refurbished card and it was missing some of the pads, so I asked support for some replacement pads and then sent some out. I think the issue most people have when they repad the card is they are selecting pads with a shore hardness that is way too high and are getting poor contact with the card the factory ones are almost putty like which might be ideal as the surface is uneven.

I wish EVGA would send me replacements like I asked for instead of trying to sell me EVGA's Thermal Paste because they didn't pay attention to what I wrote in my ticket.


Unless their paste is as thick as the putty I can't imagine suggesting I buy the EVGA thermal paste to replace the putty.

Also they seem to want to believe that no one should ever, or very rarely, need replacement pads like they don't dry out and/or get ruined when you take the GPU apart.

The Thermalright Odyssey Thermal Pads does a very good job to drop the vrams temp

Just a quick question, If I'm planning on installing a ek block to my 3090 ftw3 and using thermalright pads, would I still foow the installation guide for thickness of the pads? Or would I have to increase the pad size because the stock ek blue pads are pretty hard. Any insight would be greatly appreciated.

Would love to know this as well since i am doing the active backplate as well!
 
TY all

thx for the info

So if i understood, the thermal paste use by EVGA in factory is better than others pad ?
 

 
Thermal paste is not the same as thermal putty or thermal pads. Thermal paste is used when the heat sink sit directly on the chip (GPU). Thermal putty or pads fills in gaps (1mm to 3mm) between the chips and heat sink (VRAM, MOSFETS).
I have gotten better performance using thermal putty then thermal pads.

I did not take photos.
 
If you did not take off the heat sinks and scrap off the stock thermal gel, I would leave everything as is. The card as it is from the factory has fairly good thermal compound and thermal putty.

I got this product- Loplilip may have even been talking about my post. (if you use it make SURE YOUR HANDS AND ANYTHING TOUCHING IT ARE CLEAN) I have a 3080 ftw hybrid (DIY kit that I used all stock paste and pads on GPU side provided by EVGA) 3070ti and 3090 ftw
 
over the weekend I pulled off the back plate of my 3080 and 3070ti. the 70ti only has a 2 places with stock thermal putty. I removed it and slapped on the putty in the image. my temps did go down a few c's (GPU side is untouched and will remain so unless EVGA makes a hybrid)
 
for the 3080 hybrid there is a lot more real estate. this putty is great. its very soft (and sticky) I dabbed on each connecter and chip face on backplate side (nothing on GPU die as its open air and I don't want to cover it) I treated the putty like paste. dots that will compress with the placement of the backplate and "compress and squish for contact". temps dropped a few more C's than the 70ti and I believe that comes from the active AIO on the other side. I will be attaching heat sink fins with thermal tape today after the tape arrives. I strongly believe the goal is to wick away the heat on the backplate to have any hope of lowering the mem temps. I have some 350CFM fans that sound like jet engines when going full speed (5500RPM) and those do well to wick heat off the plate. I feel as though adding the fins and tape with the direct fans will have good effect. my door bell just rang, I will report back after I attach and note temps. 
 
*I will not have pre mod temps as mine were close to what others reported for both mining and gaming.*

Can someone give the correct thickness for 3080ti xc3 pls?
