can someone point to where the mosfets are? would like to know so i can put the proper mm thickness. kritical pads for ftw3 3090 are out of stock but their full pads are in stock. might have to buy a full pad of 1mm and 2mm. 
 
 

Funktionieren diese Wohl ?

Habe mom nen Byksky Wasserkühler Montiert und würde die 3090 aber gerne als Luft Variante Verkaufen, welche Pads soll man jetzt nehmen gibt es da neue Erkenntnisse ?

Just here to confirm, that the pad mod is an absolute pain to get right on this card. I do not recommend to do it at all, unless you are willing to take the card apart multiple times and are satisfied with one digit gains.
 
I used Alphacool Rise Pads (2 and 3 mm) on the VRAM and the VRMs as they are very soft and pliable, almost like dough. For the coils next to the VRMs I used EC360 soft pads (1mm). 
 
I don't see any improvement on the Memory Junction Temperature and only slight improvements on the temperatures of the ICX3 sensors.
 
I believe EVGA did a god job an the thermal pad selection and that the cooler design is simply not capable to deal with the additional heat of improved pads. I guess I'm going to invest into an Alphacool Eiswolf 2 AIO at some point.

 Ok, im gonna put up what ive done with some very good results and give everyone some hope here. So i tore down my card and put the hybrid kit on recently, but i didnt change the pads that came inside the shroud, just the TIM for the gpu, which i used TF8 for and of course i cleaned the mem and gpu before hand. That all went fine with no problems. For the rear though i did some experimenting. I got a bag of copper shims, an assortment of 100, that all came in stacks of 10 different sizes and thickness' up to 2mm thick. I lined them up over the mems, 2mm thick ones, and the widths were good but they were a little long so i dremeled the extra off and sand/polished them. Then i put TF8 on the mems, just enough to cover them thinly and entirely.That way the TIM fills in the micro imperfections and then added the shims on top.Once they were all on i put strips of Fujipoly ultra extreme 17w/mk 0.5mm on top to mate the shims to the backplate with. Screwed the plate back on and it was perfect, even slightly tight id say with a very slight hump over the mems, but barely noticeable. It worked really good, way better than i thought it would.
 Thats only half the battle cause i still had to mount the rads, evga cpu AIO too. So in my case im a little limited for placements without a bunch of chopping, which i can do no problem but i really didnt want to tear this case up....yet. So i mounted the Noctua 3000 rpm industrials to the gpu rad and put that up front, hoses down, and this will be the one that draws the air in since the gpu doesnt run as hot as my cpu. CPU rad went behind the gpu rad with push/pull and EK Furious vardar EVO's 3000 rpms too, but the cpu hoses had to go up top or it wouldnt work. All these fans went to a proper fan controller, FC2, and got Phanteks Halo LUX RGB frames also....it was a wiring nightmare. So i ended up with maybe a 3/4" gap on both sides where they are mounted so i stuffed 1" soft foam in that gap to seal the air off from spilling out the sides and snugging up the rads.
 I know this has been quite a problem for alot of people but this little mod seems to have done the trick. So YES, there is hope. If you need any other info let me know and ill give it to you. I dont want to turn this into a book here! Good luck to those who try it....i think youll be really pleasantly surprised if you try it.

Thanks for this thread.  I took apart my 3090FE with little to no difficulty and saw immediate gains.  Looks like this will not.
 
Also FWIW, I tried putting a fan and heatsink on the back of my card, and it still hits the same temps as it did without it.  I wonder if the hotter memory temps are not on the backplate side.

Does the heatsink make good contact? I found with pads under my 3080ti backplate, it flexed enough that a single large heatsink didn't make enough contact to be effective. Only going to several small heatsinks saw any improvement.

I believe it does because when I touch the heatsink it is hot to the touch.  I actually used an old AMD CPU heatsink on the back of my FE card after repadding it and it dropped the temps 5-10C.  I ordered something like this for the 3090FTW3.  And then I put a 120mm fan right on top of it, and it didn't change my temps at all.  If anything, maybe the fan spins a few percentage points slower?  

My opinion on the whole pads thing, especially on the back of the cards, is that if you install the card in the mobo as normal all the heat is going to rise, so everything in the back gets cooked and needs proper dissipation. Then they have 2.5mm or slightly less thermal pads on the vram chips which will help but at that thickness is more suffocating. Take them out of the equation and replace them with copper/TIM/very thin pad and it changes the whole thing. Im not going to get into how good my number drop was cause everyone is going to get different results but if you do it right it will be worth it.

I fought this early on in my build before I went full on nuts.  When I fired up the FTW3 Ultra and ran it the poor thing hit 105C in a matter of minutes on the VRAM.  Even the TRex miner program was screaming through red numbers.
I then went down this rabbit hole thinking the pads would actually do something.  In respect to mining, the results were irrelevant at best.  I learned very quickly that trying to maximize hash rate by OC'ing the card was a simple no go if you want the card to live more than a few months.  Instead of the estimated 120 m/h I run it with the GPU at -250 and leave the rest alone for 108 m/h on average.  After a short stint I decided water cooling was the next stop.  Ordered the EVGA hybrid kit.  Well that does nothing for the VRAM.  I then jumped into custom loops.  I got the Bykski backside cooler plate and put together a small loop.  This dropped temp's substantially.  From constantly near 100C to low 80's or high 70's.  After that I just added more cards and more loop and then a second rig.  Now I run four 3090's on two rigs in a Lian Li DK05 desk.  Temps are harder to control running to systems in one case for sure.  I'm back to low mid 80's on on one rig, and just high 70's on the other.  But good lord does this desk emanate heat. You could sit at the desk in the winter and not run your heat.  It's that hot.

Luckily, my temps werent that bad when i first got my card. I wasnt mining either, just gaming on very high settings at 4k. I knew they were only going to get worse so the Hybrid kit was going on at some point. The backside of the card was a different deal. I searched and searched to see if anyone did it the way i was thinking of, and did eventually, and there wasnt anyone i could get results off of from that particular setup/mod. So i just did it myself and it made a big difference. Thankfully cause i was gonna spend the money and go full custom loop for both the gpu and cpu, which i really didnt want to get into. Lol, though i understand what you mean about the heat comin outta that thing and thank goodness i dont have that much cause the little that does come out is enough. Summer must be terrible for you if your trapped in a small room!
