How are we supposed to properly replace the thermal pads when it is not even possible to buy those heights?

At retail you can only buy .5mm steps. There are no .25mm steps for commercially purchasable pads.
Also you can not buy thermal putty, it is not sold as far as I am aware.

 Edit: This appears to be a much better choice: https://www.digikey.com/e...4863?itemSeq=370979172

K5-PRO has thermal conductivity K>5,3 W/m.K that is so low- I have thermal TAPE that is rated the same. would not recommend 

Yeah I did more research & I agree. Looks like I'm going to get some TG-PP10 thermal putty instead

Mine's a 3090 as well.. just gonna test out 2.5mm pads. Otherwise I'm selling this garbage for a Strix. And it's terrible cause EVGA has the best customer service.

Did you try Gelid Extreme ?
I use the hybrid kit on my 3090 FTW3, but it seems the pad provided by EVGA are not good, and specially on the copper part.

but i think i would to buy original hybrid kit premounted, or kingpin.


 

I find that ThermalRight is plenty good. It's been more than enough to keep the temps of the VRAM way down. You don't really NEED the best of the best of the best, just not the worst of the worst of the worst, which would be Gigabyte's stock thermal pads, insanely bad, and they **** oil onto the fans which spray it everywhere. If you get a Gigabyte, replace those pieces of **** before you even turn it on. But my 3080 XC black when I was first putting it through its paces wasn't throttling at all. It was the first of a few cards I'd seen that didn't insta throttle when mining. I decided to not replaces the standard thermal pads on the EVGA XC3 black and only put thermal pads behind the VRAM connecting it to the backplate, which I don't know why the AIB's don't ****ing do that. It's so annoying, that backplate is a heatshield! It traps heat inside the graphics card and allows no airflow to take heat away from the back of the card. They are a scourge of modern GPU's. But credit where it's due to EVGA for making a backplate with a bunch of hexagonal holes all over it and a large area just behind the core. There is way more potential for air to get in there with that kind of backplate. I don't know if all of EVGA's are like that though. Even if you aren't mining, I'd still recommend connecting the heatshield/insulator/bull**** backplate with some at least ThermalRight pads to the backplate so that it isn't just hurting your thermals but instead helps them. God, **** backplates. They're a case of pretty over performance. 

The measurements provided by Lee, pre-date but do they cover the 3080 Ti FTW3 as well? Thicknesses of 2.25/2.75 appear to be atypical for 3rd party vendors, I'm looking for pad thicknesses (Thermalright, Gelid etc.) that will accommodate the EK Quantum Vector and associated Active Backplate, thanks.

Are you asking for pad thickness to attach your water block and backplate? If so, just go to the installation manuals for each to get the thickness, then order from your preferred pad maker.

yes and thank you, I do have the manuals now but was actually looking to hear from those who have this same setup as I have with comparing the quality of their pads which I hear are not very good vs 3rd party.

Compression effects the thermal conductivity. If you buy 3rd party pads they may not work as well because they're being compressed to the EVGA thickness.
Ask EVGA for a set and make sure they send a full and complete set of thermal pads for your GPU.
They've sent me a generic bare minimum set twice and I still don't have the full and complete set I asked for.

right on the compression aspect, but I'm using EK block and active backplate along with of course their pad dimensions which comprise 1mm, 1.5mm & 2mm, but with Thermaltake Odyssey pads

For the Hybrid Kit on the 90, can we use 2.5mm pads 2+.5 and 1 mm pads since theres no pads available in increments of .25?

I recently purchased an EVGA GeForce RTX 3090 FTW3 ULTRA GAMING video card, 24G-P5-3987-KR and after the first use I saw that the video memory heats up rapidly to critical temperatures of 108-110 degrees in 1-2 minutes, but the core remains cold 35- 40 degrees. I want to add that I have 7 of the same graphics cards and I know that the memory of that 30 series is hot, but none of my other cards reaches 90 degrees in memory even during prolonged use. I inspected the map visually and noticed that in one city from the backplane side the thermal pad is not tight with the memory chip. I'm adding a video to show you exactly what I mean.So do I need to contact EVGA or can I just remove the backplate and replace one gasket? Will I lose the guarantee? Thanks !

Nope won't void your warranty.  Easy to remove too and won't affect the mount as long as you don't remove the 4 screws around the core.

Thank you very much for the answer, but to change one piece of thermal gasket on one chip I will have to open the backplate, and one of the bolts has a warranty seal (sticker)

I just successfully remounted using 2mm Gelid Ultimates.  Didn't reduce temps as much as I had hoped though.  About 6C.  If you use Gelid Extreme pads (much softer than Ultimate), you could use 2+0.5 or 1.5+1.0.  Just try to stack them without any air gaps.  I think some people put thermal paste in between.  Not sure if that helps but probably doesn't hurt.

Nice! What were the temps before? 
 
I'm waiting for my 1mm pads tomorrow. Purchased a full set of Gelid Ultimates. I asked evga support and they said to do 2.5mm and 1 mm. Now I just gotta decide 2mm or 2.5mm :( Going to compare with the existing pad on the hybrid and see what looks similar. I bought a 11g tube of kyronaut to add inbetween the pads and top of the pads for contact.

would any of these sizes qualify for the 3070 ftw3 ultra?
my wife got wasted and yeeted a red slushee at me and my pc. Got all of it off the 3070 with 99% isopropyl but I trashed the pads thinking I’d put better ones without looking up the sizes first… after reading now I’ll never do that again lol.
