do the 3090 kingpin hydro copper have aftermarket backplate to lower the temp?
Same exact back plate as the hybrid.

running a mp5works active backplate on my kingpin hc and temps never break 75c mining or gaming lately with house cooler they even been staying right around 68-72c.

Mp5works definitely makes a difference... Not breaking 78C with super hot room while mining... Definitely above 27C ambient. Optimus block report similar result with there XL backplates as active cooling... I wonder what a combo of... Better pad, Optimus XL, and active mp5works would do to the temps... 😜

The thermal pad is provided, but I believe it is a 6W/mK and is cut to the block size which is 14x6 cm

Hehe I think it's like 0.5, or 1mm... But it truly doesn't matter. There is no obstruction, both sides are flat. So technically as long as it squish enough, take it as thin as possible, faster for the heat to be transferred to the water.

the mp5works backplate cooler is a universal add-on. I didn't want to have to wait, so I went with this.
Bitspower Galaxy Freezer DIMM6 RAM Liquid Cooling Block - Ice Red BP-WBDM6AC-IRD (performance-pcs.com)
you just have to get a good thermal pad, fittings, and figure out how to affix it to the card.
later,

Not really any wait time i ordered mine on a sunday and following monday was a holiday for americans so money didn't clear till tuesday and they shipped it out on tuesday i had it on friday.

2.5mm pads between PCB & backplate.
Thanks - good to know.
I'm guessing "squishy" 3mm might work as well? I'm sitting on the Thermaltake pads right now, 2mm and 3mm thickness.
All thermal pads will have some give to them, some much more than others. I would say avoid going 3mm unless it is verrrrrry soft but you won't know until you get them which is the problem (unless you have a frame of reference for their tech-specs for "hardness").
The official recommendation from EVGA is 2.5mm on back VRAM and 2mm on back of GPU die (MLCC's). I used 2.5mm Thermalright pads for everything and it works perfectly fine, fantastic results. You will probably be perfectly fine with anything in the 2.0-2.5mm range.
Great, I'm actually sitting on 2 and 3mm Thermaltake pads. Would the 3mm be sufficient for the VRM if I decide to have a go at the front of the card to replace the putty?

Sorry all, I started reading a few pages of the thread before realizing it was 39 pages long.
Is there a consensus on the pads (thickness, locations, brands/model) to use for a 3090 FTW3 Ultra with the Hybrid kit? It's the standard backplate as far as I understand it.

I'm still waiting for someone to put out a backplate for EVGA cards that'll allow for the installation of not only an augmented rear heatsink, but also have mounting ability for something like a 92mm fan using the on-card PWM header.

Okay- I have possibly the dumbest question ever recorded on the entirety of the forums. but what if you just "blanket" the entire back plate in a solid sheet of thermal pad? instead of hitting just the heat generating pieces?
I await and will prepare to be downvoted into oblivion.

Everyone needs to ask EVGA for full sets of replacements.
If we can not buy the correct sized pads at retail then EVGA should be providing us with replacements.

Honestly, I was wondering about that too. Can someone just put a big sheet of thermal pad covering the entire backplate and then put a big aluminum heatsink on top of that? There's a bunch of holes on the 3090 FTW3 Ultra backplate, so it might cut some airflow? Not sure if those have that much of an effect on temps though... hmm

well, if the back of the card was flat and every component was at the same height, sure this would probably work (at significantly more expense for the thermal material), but since this is not the case, it is easier to use the varying thicknesses to hit the spots needed. it's not that much additional effort either, just takes some reading and patience. if you're really turned off by this process, optimus is getting ready to drop their active backplate water block. it will be expensive, but worth

Yea you'd probably end up with poor contact on the VRAM and make it worse.

I just did the thermal pad swap on the back only for my Kingpin 3090 and now I'm getting worse temps than before. I went with the Gelid Ultimate 2mm pads for the entire mod but tried to flatten the padding where it was higher than the memory pads. I'm wonder if the pads on the memory are not snug against the backplate anymore. Should I have used 1.5mm for the resistors (or whatever they're) which is higher than the memory? I did order some 1.5mm pads but didn't want to leave my PC unfinished until the additional pads arrive. These temps include a heatsink and fan laying on the back of the GPU.

You are bang on with all your assumptions. Looks like the pads on VRM areas are preventing good contact with the memory chips. The memory chips are almost surface level compared to the sp-caps which are probably at least 1mm taller if not 2mm. You can either replace the thicker pads on the VRM areas with thinner ones or replace the thinner pads on the memory chips with thicker ones.

I just ordered 1.5, 2.5, and 3.0 pads. That way i have what i need once i open the back again. Not sure how compressed the current pads will be.

If I recall when I took my backplate off kingpin that only the memory and back of die had pads, and the Block kit came with pads for just the same.
It makes sense, the block (even the heatsinks with AIO) will take care of the components on the front, why saturate the backplate with extra heat?
the cooler the plate is the more heat (faster) it will wick away from the memory.

I received the 1.5mm thermal pads and replaced only those. Left the 2mm pads as is. While the temp did improve slightly, it is still worse than stock. Do I need to replace the 2mm again as well? Maybe they've been compressed too much? Would it be beneficial to go with 2.5mm pads? Temps: https://imgur.com/Gjbw3gL

I think dagger had problems with the gelid pads they were to hard and didn't compress enough if any thing was uneven. after you squish them put a straight edge across the back and see if they are still holding other spots away. Also there is the same problem i had and the heatsinks wern't big enough and when the heat transfer to the back plate was improved and more added to it extra pads...they couldn't take the heat away feel the back plate and heat sinks they should be cool if they feel hot you need more cooling! I went through 3 set of heatsinks before i settled on my big ones with out the back plate going to put the mp5works block on as soon as i get the rest of the parts for my loop hc block is also going on.

Do you think using thermaltake 2.5mm pads would be better for only the memory? On my heatsink i also have a 2200 rpm fan.

The kingpin is technically developed for LN2 maniacs (nothing wrong with that... Would love doing it). And so everything is built around that use case. Then you work with those gddr6x is a massive headache, that backplate warm like the sun... So that's reason 1 I believe. Second reason at least, make it it yours, or simply loving the modding in general 😉

I thought the Kingpin was partially watercooled.....for that kind of price I would expect it to run cool no matter what you do. I have two 3090 FE's . Replaced the thermal pads on the back which helped a little bit. Added some Alum heat sinks which also helped. Just ordered a few of the M2 Ram heat sinks with fans on them. Hopefully they will lower temps significantly. Right now I hit 108 mining ether.
