Hello community,
It's been a very long time since I bought this card and I've decided to look into the pad sizes that this card needs for replacement. According to the following link: (nvm can't post the link. EVGA FAQ# 59822)
The sizes for my card are as specified:
28x14x2 QTY: 2
58x14x2 QTY: 1
88x12.5x0.75 QTY: 1
88x10x1.25 QTY: 1
10x8x2 QTY: 2
90x27x1 QTY 1
 
I decided to go with Gelid pads. Finding the replacement pads for sizes 0.75 and 1.25 are challenging. They're out there for other brands but in huge quantites that just seem wasteful and expensive to me. I'm sure the 0.25 difference may be necessary. But from anyone elses experience, is there a closer to standard size that I can use that will do the same job if not better? Open to all suggestions
Edit: I'm also curious if the pad placement is pretty solid from the factory or if there are suggested places I should add more while I'm in there

    Welcome to the EVGA Forums & congrats on your first thread

    You want to use soft pads or the GPU to cooler contact will not be made, as those 4 tiny springs do not give that much force.
     
    You should always do a test assembly before you place the TIM on the GPU to confirm proper contact with the components -- proper contact should leave an indentation in the thermal pad material that is clearly visible when you disassemble the cooler if the pads are the correct thickness. 
     
    Good photo example of impression check, can be found on the EKWB site.  https://www.ekwb.com/blog...al-interface-material/

    (excerpt)
    "When you remove the cooler you should clearly see the imprint of the edges of the elements on the PCB. When the edges aren’t visible you have no or bad contact. The contact can also be too good. You can observe that when you check if the motherboard/graphics card is severely bent in the area of the thermal pad."
     
    So, I'd start with "next size up" if .75mm is not available, try 1.0mm & you could try the next size thinner; but, you need to confirm contact between the cooler & the pad ... not imprint, then it is too thin to function.  There is always some variation in manufacturing so the listed thickness is a nominal thickness. So 1mm could be thinner or thicker depending on the Mfg +/- specifications

     
    Once you have the pads installed with contact, do a test assembly to confirm you can get a good TIM pattern.  Place the rice sized blob of TIM in center of the GPU & assemble the cooler.  Next, disassemble the cooler & confirm you get good spread of the TIM, to indicate the heat sink is not being held away from the GPU by too hard or too thick of thermal pads.  You also get to see if your using too much or too little amount of TIM
     
     
    FYI: Stacking thermal pads does not transfer heat as well as a single pad, best to buy the thickness needed
     
    As far as buying a "custom pad kit" --> I found this review on overclock.net Kritical Thermal Pad Results - EVGA 3080ti XC3 Ultra Gaming
     
    I have never used the brand "Kritical" so I have to say do your own research & check reviews, but it seems they sell thermal pad kits
     
    There are a couple of Kritical brand pad threads on EVGA Forums, that I found
