Have anyone tested Gelid Solutions GP-Ultimate 15w/mK in the KPE? Currently using Thermalright 12.8w/mK.
Anyone knows if thermal tape is strong enough to hold a heatsink on the back of the card? (KPE is vertical mounted). Planning on using the following to cool the backplate + a 120mm fan:
https://www.amazon.com/Aluminum-Heatsink-Amplifier-Transistor-Semiconductor/dp/B07VMMJCLY
https://www.amazon.com/Ceatech-Thermal-Double-sided-Adhesive-Computer/dp/B072JJD2ND
That should make a pretty good difference use a taller heatsink if you can fit it. Even the cheap thermal tape i have used on different stuff over the years i normally have to scrape off or use googone to loosen it up. good way to know if the heatsink is big enough it shouldn't be hot with a fan on it! bigger is better if you can make it fit and get lots of air over it! @dabadger could tell you more about the tape.

Thermal tape is strong enough if you use enough of it. I had mine like that for a while, large aluminum heatsink held on backplate with thermal tape, mounted vertically. I just stepped up my game big-time though and finally replaced thermal pads between the backplate & PCB, replaced thermal pads on front VRAM and re-pasted the GPU with Kyronaut. Permanently removed the plastic shroud on front of PCB and then modified my aluminum heatsink so it mounts directly to the backplate with screws, enabling me to use thermal pads betweeen the backplate and the heatsink with perfect mounting pressure and sturdy as hell. About as good as it can be while I wait for a waterblock, probably not a lot to be gained from a waterblock at this point lol. *Edit- As for the Gelid pads... probably not worth it over the Thermalright. 2w/mK difference. You might notice a difference with Fujipoly 17w/mK but they are very expensive. The Thermalright pads are fantastic value IMHO, relatively speaking.

its a ftw3, yes the back plate is almost like that. did you replace the thermal pads on the heatsink with better ones or you just used the ones that come with the heatsink? for the 3090 fan is it blowing air out or blowing air in? want to ask this because i have a bottom fan blowing air into the gpu fan
Initially all I had was thermal taped heatsinks on top of the backplate with a fan blowing over them. I did more "modifications" later. Just the heatsinks with tape will help. Anything additional you do after that will help even more. I went from just the heatsinks with a fan, to redoing thermal pads, to adding more thermal pads in other heat producing areas & additional heatsinks, then I went full bonkers using thermal past to secure most of the heatsinks to the backplate, with 12.8W/mK pads between the VRAM & the backplate.
The fan is blowing down on to the heatsinks, but from what I've seen either method should work (sucking air off of them or blowing air over them). Kind of depends on your case's airflow setup which would work better. For me, blowing down on to the heatsinks works best because my top radiator is setup as intake, so it's intaking air through the PE 360 & then the fan is blowing that over the heatsinks.
which thermal pads you brought for the heatsink? i brought the ones that you listed. after i installed it didnt make much difference and i searched the thermal pads they used on the heatsink and its very low. i tried to look for thermal pads that is the same size .25mm dont see much. I dont know if higher thickness affect anything? https://www.amazon.com/gp/product/B07JLQL63D/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 https://www.3m.com/3M/en_US/p/d/b00051394/

I finally put my mp5works to work... https://imgur.com/gallery/3kp7B4mMy memory junctions dropped to 72C with 25C ambiant. (Was more close to 90 under same conditions) No pad replacement at all. This with +1400 on the KP memory, with 120 for mining, not sure I need to upgrade the pads now. This card is not intended for mining, but purely for my personal stupidity 🤣 One thing to note, I still didn't fix my pump/fan speed for the GPU loop, still all at 100%, and I contacted Jacob about it, they say hubs are not supported or even tested to work with the GPU header (single fan is working just fine). He told me they will look into it. Can always use a raspberry Pi if nothing hehe

How much life expectancy difference exists between the different methods - tape, pads, paste?

I really owe a big thanks to Dabadger84, CptT95, SoldierRBT, and the people on the forums that helped me get up there. Before last night I believe my highest was 15,478. I think I could have pushed farther if I didn't pass out.

This is the best I can do on 22C ambient temp and 520W ReBar BIOS.  https://www.3dmark.com/pr/1069876 Going from AIO to HC allows me to run memory +1350 now for bench and +1250 daily stable. Before I was only able to do +1100 game stable. I'll add a heatsink or maybe mp5works on the back to further reduce mem temps. I'd appreciate if anyone knows where I can get the 1K ReBar BIOS. With 600-630W power draw and low ambient, it should score 16-16.2K

Nice, yeah I can do +1400 stable on bench, no artifact. As soon as I add more I have artifacts. But that is before mp5works with 25C ambiant. I start crashing above +1475 on PR with artifacts of course...
I will play a bit with my computer straight on top of my AC vent🤣 should help... But that thing is heavy as hell...

I think I have a bottleneck in the form of my 5800x, the thing is bad at peak single/low thread workloads, doesnt even hit 5 GHZ single core
I can not for the life of me push past 155xx in Port royal :(

Last night I actually finished a run at +1800 memory, but the score wasn't better. I can do +1600/+1700 pretty stable. I feel like for Port Royal, my CPU is also holding me back also. My CPU(5950x) hits 5150, but with my temps I could have an Intel pushed pretty far. Doesn't really matter if you get artifacts as long as you get a score right? :p

Funny you say that, I actually had artifacts in my old-old personal best score because I was pushing the memory really hard before I got the HC block on. When I hit 15461 or whatever it was, there were some artifacts at one point in the test. Now that I'm keeping the memory much cooler, I don't have that problem, but I still can't push even a smidge past +1400 without errors, even with 1.425V FBVDD.

Hey there, currently waiting on my own Kingpin AIO to arrive (scheduled 6/14) - while I'm perfectly willing to go spelunking in the past 38 pages to find the correct gouge, would anyone be kind enough to give me thermal pad thicknesses for the back only? I don't feel like screwing with the front side of the card. Thanks in advance. =)

Yeah after running mining all night, the mem junction high was 88c average was 78. the ambient temp of our house got pretty warm last night, so i am sure that had something to do with the high. it is sitting at 80c right now. I think I am going to get another water block for the backplate. that one is a bitspower x6 ram block and I can fit another. It is also using a thick thermal pad that I had from upgrading a mac pro, so some thinner more efficient thermal pads would be good too. Thanks, Chris

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.

This is the greatest thread. The picture is really inspiring. Once I get my card, I want to incrementally improve temps using water cooling and testing. Watching how you (all) did it is a great help. Thanks!

I'm guessing "squishy" 3mm might work as well? I'm sitting on the Thermaltake pads right now, 2mm and 3mm thickness.
I'm using 2mm pads from Thermalright and they work perfectly. The 2.5mm number from eVGA is using very squished pads (as in when I pulled them off there's a decent indent of the chip on the pad). The 2mm pads still have a very slight indent but not a heavy one.

https://dewire.shop/ ordered some 480 strips and the high power cables...I think these will work great as long as i have enough room between the fans on the push pull Ek xe rads!

2.5mm pads between PCB & backplate.
Thanks - good to know.

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.

Has anyone tried thermal putty on memory chips then thermal pads on top? It's suppose to improve heat transfer from the chips to the waterblock. Here's a video: https://www.youtube.com/watch?v=vavSs98JV_g&t=22s Since the gap is reduce with thermal putty maybe Fujipoly 1.5mm 17 W/mk can be used now. Just a theory.

I’ve used that TG-PP-10 stuff on the Memory, no additional pads, and temps were worse than stock pads so I removed it.. I had spread it on pretty thick (2mm+), so not sure if a thinner layer + pad on top would be better..
Interesting, but I’ll leave it to someone else to test because cleaning the putty was a pain.

do the 3090 kingpin hydro copper have aftermarket backplate to lower the temp?
