    well, why did you use the wrong size pads?

    The Fujipoly pads have no give to them, which causes the majority of the bowing.

    Are you using the stock backplate? If so, there wasn’t much need to change the pads out unless you needed to remove the backplate.

    Personally, I like the primochill pads as they have seemed to last longer and have slightly more give to them for conforming to the products they are covering.

    Per EvgaJacob the back Vram is supposed to use 2mm pads. Ive heard of some folks on here using 3mm very soft pads but they also get Backplate bow.
     
    My thought is to try some 1.5 mm 17w/mk fujipolys tonight. Can anyone comment on if those do better or not?

    I mounted a waterblock that uses the stock backplate. I tore one of the pads when I pulled the plate and in general I thought i could spend some money to get some better performance.
    ill check out those primochill pads.
     
    Before, I had a bunch of 14x14 copper fin heatsinks on the backplate that would get very hot to the touch, now they arent getting as hot so i know my heat transfer is bad.

    I found a treasure trove of Info here. Looks like 1.5mm is the way to go.

    3090 ftw3 here. I replaced the backplate vram pads with TG minus pad 8 3mm. Definitely a slight bow there, but the minus pads are pretty squishy so I think I'm okay.
     
    I ran out of 3mm on one section of the vram on the back so I stacked a few spare pads there and going to replace with Fujipolys (minus pad 8s all sold out). I know the 17w/mk are super stiff so I bought the 11w/mk stuff. I was hoping the 11w/mk version has better squish.
     
    Anyone have any experience with Fujipolys 11w(x-e) vs 17w(xr-m)?

    I think 60s-70s while gaming, I cap out in the 90s while hammering it with furmark.


    I'm also going to try slapping some heatsinks on the backplate over the vram sections.

    17 w/mk Fujipoly pads are highway robbery.
    It takes so many packs just to do one side of a card.  The packages are THAT small.
    Paying $37 for a 60mm * 50mm square?  Are you really that rich, man?
     
    Here.  Instead of throwing away your money, buy a collection of these of different thicknesses.
    You can get 0.5mm, 1.0mm, 1.5mm and 2.0mm for the same price as ONE fujipoly 17 w/mk pad.
    The 200mm * 200mm * 1.5m pad is out of stock, you can buy the 100mm*100mm version of that.  
     
    https://www.amazon.com/gp/product/B086VYKZN4/ref=ox_sc_saved_title_10?smid=A2XFN3HMWVK6C2&th=1
     
    Buy the 200mm * 200mm ones unless they're OOS.
    Then you can practice experimenting on the backplate until you find the proper thicknesse that works best and gives you decent temps and improvement over stock.
     
    Once you know the exact thickness, THEN buy something better, like Gelid 12 w/mk pads or Thermalright Odyssey 12.8 w/mk pads! :)
     
    You can buy large, better value for the size, samples like these, and then have good heat transfer.

    Well they say fools are easily separated from their money... the 1.5mm fujipolys are already on my desk.

    If i dont get equivalent to stock i will try your recommendations

    Fujipoly's are nice, but not worth the price to performance.

    So it's 1.5mm for the vRAM areas of the backplate on the 3090 FTW3?  Wonder if it's the same measurements for the Kingpin.  I'm debating buying some thermal pads for other areas of the backside of my card, wondering if I should get 1.5mm or 2mm, or a mixture of both, since I'll be putting some in areas other than the vram chiplets.

    If I remember correctly, you got a FTW3 3090 Hybrid, is it possible for you to get some temps on the back of the card? Thinking about doing a hybrid kit but I doubt that's going to affect the back VRAM temp :(

    Answered your PM.  I'm pretty sure one of the 3 vRAM iCX temps is on the backside of the card - the warmest of the 3, would be my guess.
     
    I have a 3090 Kingpin now, haven't had the FTW3 Hybrid in... a month?  Wow time flies.

    So is it 1.5mm for the vRAM & 2mm everywhere else, or which?  I'm fixing to order pads for my experiment that's taken on a life of it's own, going to do thermal pads on the backside of the VRMs & all that jazz, trying to lower the GPU's PCB heatsoak as much as humanly possible - so far just the heatsinks are being quite the success, but every little bit counts when you're already getting down to the temps I am.

    What a fail. The 1.5 mm fujipolys were an obvious no-go because the single ram chip would always show an air gap.

    The backplate really is not rigid so mounting to these firm pads is literally a moving target.

    I reverted to stock pads but they perform like crap now. My rig is going to stay down until I figure out a pad solution or a backplate solution.

    I replaced the thermal pads and added heatsinks to the back. Also have a fan blowing on them too. Dropped my memory junction temps by 10c. Not an exaggeration either, I topped out at 92c on furmark prior and now I'm peaking at 82c.

    That's what I'm figuring with the heatsink layout I'm doing - people that have higher temps will see larger drops in temperature than I did.  I started out with fairly docile temps compared to most, so the fact that even I'm seeing 3-11C drops in memory temps is pretty darn impressive.
    I'm going to be replacing probably all of the thermal pads between the backplate & the card, and adding more in areas I want them in, on probably Tuesday, once all the pads I ordered arrive.
    I'll have to document the heights of stuff on the back to figure out what exactly is needed in each place, and how squished the memory pads are that are on the card stock.

    That's what I'm figuring with the heatsink layout I'm doing - people that have higher temps will see larger drops in temperature than I did.  I started out with fairly docile temps compared to most, so the fact that even I'm seeing 3-11C drops in memory temps is pretty darn impressive.
    I'm going to be replacing probably all of the thermal pads between the backplate & the card, and adding more in areas I want them in, on probably Tuesday, once all the pads I ordered arrive.
    I'll have to document the heights of stuff on the back to figure out what exactly is needed in each place, and how squished the memory pads are that are on the card stock.




    Yeah definitely. I was actually debating between the the aluminum ones I ended up choosing vs copper ones. I know copper transfers heat much better, but there typically isn't much protrusion with copper while aluminum heatsinks usually pop out more which I assume would have more dissipation of heat. Would be nice if someone tested both. You gunna try copper heatsinks?

    I replaced the thermal pads and added heatsinks to the back. Also have a fan blowing on them too. Dropped my memory junction temps by 10c. Not an exaggeration either, I topped out at 92c on furmark prior and now I'm peaking at 82c.

    The pads that you are using are 3mm Thermal Grizzlys?

    i used Thermalright ODYSSEY THERMAL PAD 2.0mm on the backside Vram
     

    Temp is not bad

    Correct, but as I said the size is wrong. There is definitely a bit of bow on the backplate. You probably need 2.5mm with thermal grizzly minus pad 8s. I only have thermal pads on the memory on the back. My vrms are totally fine.

    Whats stopping us from putting copper heatsinks directly on the ram chips with thermal paste?
     
    I am pulling my hair out (already bald) trying to make pads stick to a plate to then transfer to a heatsink... why not cut out the middle man?

    Well i assume the backplate is providing support to the pcb, but i assume that would have the best results. I do feel though, that the backplate provides some sort of soak for the heat.
