You will never burn up this card with stock backside cooling, it just won't run as high of clocks due to relatively higher temps for those pushing these cards to the heavens lol

For those of us with Custom loops. Looks like EK has us covered. I'm still waiting to buy a card...  https://www.ekwb.com/shop/ek-quantum-vector-xc3-rtx-3080-3090-active-backplate-d-rgb-plexi   

As i'm not running a 30xx card yet... but my rig  has 2 XE 360 up top in a case labs M8. 6 varders in push pull around 900-1000 rpm. 5 varders in front supplying cool air. the 9900k while gaming sits around 45-50c and the 1080ti well it doesn't touch 45c. Just waiting to get a 3090 or a 3080 or even a 3080 ti. Been in que forever now.

ok, so since I plan to run stock settings, I should be fine.
 
I don't even need to overclock my 3070 for my games since my monitor is currently only 1080p
 
Thanks,
Chris

What I meant was that to get these benchmark high scores like these nutcase are doing, requires extra cooling, most usage of this card doesn't require extreme cooling modifications, this HC cooler is already phenomenal on its own
Edit- of course those running LN2 and DI will already have a kp hybrid by now, which is 300 bucks cheaper then the hc

460 for the 4x8gb 4000cl15 kit rgb series vs your royal series

Taint no way in H-e-double-hockey-sticks I'm getting anything but Royal.  I actually care about the look & I love the diffusers on the Royal line now that I've seen them in person.  I know it's bonkers to pay $40 more for a look, but I'm doin' it if I decide to get them. lol

someone needs to cnc a backplate with wc or fan mount.
 
I am worried about burning up a $2500 card.
 
later,
Chris

Eh, not really something you actually need to worry about, you can spend less than $100 on better pads & some heatsinks & get the backplate side stuff cool, and if you're running a HydroCopper Kingpin, the face side is already going to be cool enough.

That looks awesome - but it won't work with Kingpin cards, the layout is different enough compared to an XC3 that it would not be compatible with the HydroCopper or stock card I don't think.

He's quite right - you can just add heatsinks to the back of the card, which some people have done, with no other modifications, and even just that will drop your memory temperatures a weebit - with no taking apart of the card required.  The Kingpin comes with stock pads between the backplate & the backside VRAM as well as the backside of the GPU Die - they're not "great" pads, but they do a well enough job.  The problem with the backplate stock is, it's acting as a heat spreader - there's no fins or anything to help get the heat out where it can be dissipated easier, adding heatsinks fixes that.

I was wondering what Wattage KP draws in default settings and has anyone got an undervolt that could drop 120+ watts and maintain almost stock performance?

Technically speaking the 2100MHz @ 1025mV undervolt that I run probably does that.  I haven't actually tested it extensively - I know it's stable because I run it for less intensive games (CS:GO and whatnot) because it's still higher than the stock boost clocks, and 1025mV draws way less power, and runs cooler, than stock, by a fair bit.
 
I'll have to run a quick bench at some point & see what it draws in comparison to stock or my 2160 @ 1068mV settings.
 
For stock arse-stock draw, it is usually in the 400-480W range - some games and benchmarks can get it up near 500 at stock, apparently Metro Exodus Enhanced Edition is one of them, I haven't played it yet ^_^ looking forward to it.

i saw a video on linus tech tips about this...interesting tip

That bassard stole my idea? J/K I do find it funny that a major youtube tech channel is covering it at all though.  Almost all of them have mentioned how hot the VRAM gets on 3090s but I don't know how many have actually mentioned how simple the solution can be.  Especially on anything with a decent (and importantly, metal) backplate.

I was browsing ebay, and it looks like maybe scalpers didn't get the kingpin HC. There is still only the 1 listing. I figured if they did, there would be more than 1 posting.
 
 

They might be biding their time.

Oh they shall rue the day. Rue the day they shall.

I actually would like to get into CNC milling :P once life calms down I might look into it. It looks like a trade that could be good for me to have :)

Mining with the Optimus block keeps my ram at a decent temp. +1448 mem, 85% PL.

Is this an ftw3? I thought they weren’t at the Kingpin yet. I’d actually regret buying my HC block today if the optimus is around the corner 🤦‍♂️

that is pretty good temps for mining on ftw3 with optimus block, given KP improved PCB and higher bin chip, means there is room for improvement when Optimus releases their block for KP cards

Just go back a few pages and it should be here somewhere from Dabadger doing same thing
Think its 1 and 2mm thick pads but not exactly sure

Is that with the HC block or stock AIO Kingpin with the Optimus block on the back, or just Optimus block on the die side with no backplate additional cooling?

Sorry guys, I misunderstood the title of the thread and posted my FTW3U.

It's no problem 😊

Hi guys,
i have new rtx 3090 kngpn hybrid. So my question is worth changing all thermal pads and paste? Or stock is good and its not worth?

Hi guys,

Stock paste for mine was very dry & had poor contact in some areas of the die. If you upgrade The thermal pads on the VRAM on both sides you'll likely notice a decent temperature improvement which can be furthered by doing the mods in this thread.

Thank you
so you only recomened change thermal pads on the vram yes? What size mm i need to change pads in vram or add new ?
I have hybrid cooler

Does anyone have a good flat and square (meaning right angles at the corners) pic of the inside of the KPE 3090 backplate against a white background (e.g., laying on a sheet of white paper)? If so and you don't mind sharing it with me, I'd like to try creating a dxf file that a waterjet cutter buddy of mine could use to make a replacement backplate out of copper. I could also use two dimensions if you have a caliper:
 
the thickness of the backplate at its edges;
the thickness of the backplate inside of the edges. 
 
While I do have a Hybrid KPE myself, I'm still waiting on the HC block and haven't disassembled my card yet.
 
Anyway, if someone can provide what I requested, TIA!
