I usually run my gpus without a backplate, would this be better or worse with the backplate + fins?
Both scenarios id have a fan on both & vertically mounted.
If you have a 3090, and you have even a tiny crazy in you, you want some form of cooling solution on the backside. Backplate, Backplate + fins, Backplate + Fins + Fans, Backplate + some kind of Water block attached to it. Nike_7688

I game in 4k and shouldn't have needed an upgrade, but during Covid I also rediscovered I like to Overclock, so I'm hoping this CPU lasts me until the next one(s) comes out. I'm not very good at it, but it sure as hell is fun. It also gives me something exciting to wake up for every day besides what is normally going on...
The thing that drives me crazy is for overclockers, most of the reviews aren't as helpful. You get way more overclocking headroom on a 10900k then you do a 5000 series AMD... from what I read. But what I read usually involves an AIO, which is kinda ... a meh comparison for me. Seeing stock to stock benchmarks doesn't really work for me either, then trying to dig and find a site with benchmarks that are relevant ... Is ... rough. Trying to find someone who measured 5800/5900/5950 to 10900k on a water chiller is even... more impossible. When my GPU isn't clogged, hoping to fix that reoccurring problem Tuesday, I run some pretty nice overclocks for day to day gaming.
I do like the review Hardware Asylum did, if you search for their Evga Z490 Dark review ... in the review they put a 10900k on Phase change at 5.45ghz. I liked seeing that, as it's super unlikely I'll reach that on water, so I know where to be expecting. Super curious to see how far I can push an 5950x on 2c-8c coolant o.O
Yes! Exactly. Actually, the Tom's Hardware review of the 11900k did some overclocking comparisons of 11900k, 10900k, and 5900x (the AMD's they just turned on PBO I think). I just posed this on the sneak peak thread, but check out this OC video. That is exactly the kind of OC I'm looking for. I love that I'll be able to tune individual cores. I've never done that before. Sounds super exciting!
I'm out on my walk I will definitely check out that video when I get back.

Running heatsinks will help in both cases. It depends on whether or not you can apply some pressure to the heatsinks on the bare components. For me, a backplate worked better than no backplate with direct pad-to-heatsink cooling on the VRAM, but I'm very sure that will vary based on application & how you mount them etc. I just had them sitting on there with a thin pad between the VRAM & the heatsink, and some temps were better, some temps were worse, vs a backplate with heatsinks/thermal pads. I'm too much of a chicken to do direct thermal paste/heatsink on the VRAM chips, I'm pretty sure that would actually probably perform the best, as long as the paste has some stickiness to it to keep the heatsink from moving around & potentially bridging/damaging components.

first time owner of kingping
There isn't really an LN2 mode per-say. The 1000W BIOS is something you have to download separately & it technically voids your warranty. The LN2 BIOS is just a 520W BIOS for the card, it doesn't actually remove any of the "safeguards" the card has in place, like the 1000W BIOS does. So it's completely safe to use. I run the 520W "LN2" BIOS 24/7. Short answer: Yes it's safe/fine to use.

So all the Gelid/Thermalright pads came in; getting ready to drain the loop and install them. Interesting side note: The 120mm fan came first and i rigged it up behind my vertically standing GPU. Just having the fan blowing on the back of the backplate dropped the junction temps from 100-102 to 92-94. I am hopeful the better thermal pads will do some good work here and have me in the low to mid 80's at my 120 hashrate. Still haven't decided on whether to do this with or without the backplate as I think they both have merits, but I'm leaning more towards using it.

We'll be building at about the same time. I'm still waiting for Inline filters. i don't want to put a new AMD block on, nor clean the GPU out, just to ... have to doit again. So I'll build once I get filters for the GPU and CPU. The backplate doesn't have much area to clog, so anything that would... just floats right through and back into the reservoir. I had to clean the GPU out again this weekend, driving me bonkers. But now instead of looking live river trash, I'm getting a fine thin layer that is just barely blocking the tiny area of the AIO block.

If you can get the heat sinks to stay in place zip ties thermal glue...thermal tape i would do it with out a back plate 1 less thermal junctions to add resistance. my tj stays in the high 80s with out the back plate its held down by zip ties and the Velcro cable ties that came with the card and mother board. I can't remember the size its posted in here some place with my ghetto pictures. It could be a lot bigger its still hot to the touch with a 3000 rpm fan on it at about 2000 rpm lots of hot air coming off it. Bigger the heat sinks the better it blows my mind how much heat comes off there v ram chips! I will play with bigger heat sinks and some water cooling ideas when i get my solid copper back plate done. Want the back plate for mounting options and use it as a heat spreader.

These are my temps for my backplate. It's liquid cooled, water chilled [Current-Low-High(Load)-Avg]:  I can sent the coolant to a designated temperature, so if you would like me to run some benchmarks at a certain coolant temp I can do that. Simulate something closer to your ambient, or just above. I'm fixing a problem Tuesday so it would have to wait till then.

I actually ended up finding about 130GB worth of garbage on the HDD that I could delete, so it's a little bit less full now... and I moved the games from my C to the newer M.2... both so it's easier to migrate and so yeah... Motherboard is now slated to be here TUESDAY, CPU still hasn't shipped yet, so I'm assuming it'll be here Wednesday, then we'll be getting in on some 3900x/X570 action from there on out. I am definitely having to resist the urge to just DO IT and order that CL14 3600MHz 2x16GB G.Skill RAM... leaning heavily toward YOLO as usual, if it were on Amazon (from Amazon directly) and not on Newegg, I would've ordered it already. I'd say it's a pretty high likelihood I'm gonna pull the trigger because I really want to get tight timings & happy RAM settings, since from what I've seen in some Hardware Unboxed videos, manually & tightly configuring your RAM can increase MINIMUM FPS (as well as average) by upwards of 10% in a lot of games, with the CPU at stock in both instances, and that's on 3000-series CPUs, I would assume it's just as pronounced on 5000-series. The Hard Drive that I'm still waiting on (10TB enterprise-grade so it's made to get abused for the entirety of it's 5 year life span, 550TB/yr written or some such) FINALLY reappeared after having ZERO action on tracking for over 5 days... looks to be here either Monday or Tuesday. I just hope it didn't get damaged, never doing the free shipping from Newegg again after that - I'll pay the $4.99 or whatever it is to at least guarantee it's coming faster than "UPS Mail Innovations" slug speed. Really not looking forward to the block mounting swap, but other than that, I'm very excited for this change in parts/rebuild.

So I'm following this to figure out how to better cool both of my 3090s... both are vertically mounted, so that presents a bit of a challenge, as well, and also using both for mining. Junction temps run high 90s, so I don't like that and would like to find a way to bring them down some. Thinking of putting them both under water, but that's a pretty good expense, especially when you're talking about active backplate liquid coolers which is what I'm hoping for. Waiting for EKWB to come out with their full-coverage active waterblock backplates for my cards - I have one EVGA FTW3 and one Asus ROG STRIX. I just don't think I want to pull them apart for minimal gains and putting more fans and backplate-mounted heatsinks isn't going to help much when vertically mounted already, I doubt.

So I think I have the kit you are thinking about, I was able to get the gskill 2x16 3600cl14 to run (I believe stable) at 3800 CL14 @ 1.5v on a dark hero (gave up on finding the 3800 cl14 kit). For some reason my 5900x & Kingpin cooperated better yesterday after gaming all night. 3rd highest 5900x/1x3090 at 21C ambient. https://www.3dmark.com/pr/978243

When it comes to backplate side cooling, literally anything is better than passive. There are folks that have dropped temps just from putting a fan blowing over their backplate, and others that have just done cheap thermal tape heatsinks & also seen drops. The more you're willing to do in terms of how much you want to put in to it (I.E. whether or not you want to redo/add pads under the backplate, how much heatsink-age you want to put on, how you want to attach it be it via paste or tape, etc), the more you put in to it, the lower the temps will go.

I'm not going to lie, the pads got expensive quickly. I put more thermal pads then I needed to, but I used them also as buffers to nothing touched that I didn't want to, so there some merely on the PCB. I am starting to wonder though, those black caps, I'll have to get a pic tomorrow, there's no reason they cannot touch the copper bare right? They're not metal.

Stupid question - I bought the heatsinks referenced in this thread. I didn't realize how sticky they are.... how does on remove these without damaging the GPU?

Ideally a plastic pry-tool, or you can just pop them off if they're the thermal tape ones... it's not on there as well as you think it is. You put them direct on the PCB with the thermal tape? That's kind of a yikes, because you could accidentally pull off an SMD if it's not well attached. I would definitely not use thermal tape on bare PCB, thermal tape on backplate is fine, but for safety's sake, I wouldn't do it on anything else. Clovis559

That is the question... lol
Edit: I ordered the shiny.
OMG I want to see those when you get them!!! Oh shang nice Timings!!!
It was supposed to be here today, but currently it is showing as "waiting to be picked up" still, so I'm expecting it tomorrow (got overnight shipping cuz I didn't want to setup the system on one set of RAM then switch later). Processor won't be here til Wednesday, hopefully, anyway, so it's no big deal either way.

had not real a special goal beside better cooling without any changes on the card itself, after a 1st quick and dirty stresstest with 3dmark the Hotspot temp was around 70C and Mem was aroung 75C, that was about 10C colder then before i think

Great, that's a huge improvement.

I did it boys! Tearing down my loop is always annoying, but this was SO worth it. Max Junction temp is now 78c! All temps went down across the board including hotspot and core. The gelid pads got backordered (and then cancelled), so I bought a combo of 1, 2, and 3mm Thermalright pads (12.8w). I actually made a mistake and had to tear it down twice which sucked BIG time. I tried to be clever and use 2mm pads on the front of the card. Well, as you can imagine that ruined the contact between the gpu core and the plate. I SHOULD HAVE CHECKED to make sure the thermal paste made a contact patch after screwing it back together argh. Anyhow, after going 1mm front, and a combo of 3mm amd 2mm on the back I'm all set! I did end up using the backplate so that I got pressure on the pads. I also stuck some extra pads on the back of the plate and stuck some mini aluminum heat-sinks to them. I have a loose noctua fan blowing some silent air directly at the backplate and this combo seems to be the trick. I didn't want to wait for a water cooled backplate (or pay EK for one), so this will do and I am very happy. Thanks to all of you for sharing your trials and errors which led me to this site and the ideas.
