Also:
When is this OC XOC BIOS getting an update?  The XOC BIOS for the 3080 FTW3 Ultra still allowed for the GPU fans to go in to 0 RPM/stop mode if you had the fan curve set to do so at idle temps... the 3090 FTW3 Hybrid (OC switch) XOC BIOS isn't allowing the fan to go below 1199-1205RPM (~40%).
Is anyone using the NORMAL XOC BIOS on a 3090 FTW3 Hybrid, if so does that one allow for the 0 RPM mode to work?  I like the GPU's on board fan being able to shut off when I'm just browsing the web/on desktop.
 
 
Edit to Update: can confirm, the "500W" (using quotes now cuz it doesn't actually hit 500W when it says PWR in PerfCap) NORMAL XOC BIOS for the 3090 FTW3 Hybrid DOES allow the fan on the GPU itself (for the VRMs etc) to go to 0 RPM/stop mode while at idle temps if your fan-curve is set that way.

Can anyone confirm with a specific x570 motherboard they they are reaching 500w? I want to do a test to see if its motherboard related or card related. Ill pick up the same motherboard you said works and see if i can get passed 450

Asus Crosshair Hero VIII (non wifi version). NOT getting 500...

That "thin copper plate" has thermal paste that connects it to the GPU's cooling block, which then soaks some of that heat & cools it.  The VRMs/etc do have additional black-colored heatsinks on them, or it would run a lot hotter than it does.
 
I wish someone would do an actually thorough view/install video of the kit so people could see the entire contents, because people not seeing the black heatsink portion that goes under the shroud is really freaking some people out thinking there's actually no heatsinks above the pads for the VRM etc, which is not the case - at least it better not be. lol I didn't look inside my card to check it out, I'll take a peep. 
 
---- after inspection through the backplate holes, there are indeed black finned (though they're thick fins & spacing is a bit wide) heatsinks on the VRM areas indeed.

Thank You! I asked because I have a RTX 2080TI KPE Hybrid and it uses almost the same except that the part of the VRM is entirely covered with a copper HS, and I think the copper thin plate is almost the same, also uses an Asetek 240 AIO. My only concern are the chips on the back of the card that's the reason OPTIMUS Waterblock went off Stock inmediately because it's huge, wich I could lay may hands on one, but dunno when they'll be restocked. Almost nobody is paying attention to the back part and it does help if you cool it.

 
The back of the card does have a flat heatpipe running on part of it with thermal pads connecting to the vRAM on the back to "spread" the heat out over the backplate - it's better than nothing.  The big difference with the Hybrid vs the non-Hybrid 3090 is the fact that the GPU & everything else is running cooler on the GPU side due to the AIO cooling the die, which results in less heat being soaked in to the PCB, and as a result, the vRAM doesn't run quite as hot either (GDDR6X does run hot, period, compared to earlier GDDR versions).
 
Here's some numbers I saw during a half hour or so brief gaming session in Cyberpunk - note this is with an undervolt as shown by the voltage readout during the load, but also note, the GPU core clock is higher than what it runs at stock ;) undervolt overclocking ftw! : 
 

 
If I'm correct about positioning, MEM1 is located between the GPU die & the VRM that is towards the exhaust-end of the card, meaning it's in the hottest area with the way these cards vent their heat.  MEM2 is between the GPU die & the PCIe slot, and MEM3 is either on the backside of the GPU, or between the GPU die & the VRM that is towards the fan of the card, but it is also getting direct airflow from the fan, on top of the GPU block's soak-style cooling, which is why it's running the coolest.
I wonder if Buildzoid covered the actual iCX sensor placements in his PCB breakdown for the 3090 FTW3 Ultra... it's the same PCB - I'll have to look that video up & give it a rewatch.  I'd love to know 100% for sure where those sensors are.

Running Cyberpunk 2077 ALL Ultra Settings at 3440x1440 I have those same MEM Temps on Air with fans at 77% and a fan blowing behind NOT pointed to where the caps are but to the whole backplate (the fan is in a stand at less than 1cm from the backplate and paralell to it), so it does a good job, and here it's 25C+ room temp. Core goes to 67C and max I saw was 70C. I was lucky with this card, not only on Clocks but Cooling. Those temps you have are nice but I think I will wait for a good water block instead.
 
Cheers Sergio!

Well, hybrid kit installed. The instructions weren't the best (could have said WHICH screw package to use, the bags were labeled) and it was missing the two rubber plugs for the two screw holes that weren't used. Swapped the two fans with two corsair ML120s - no push/pull yet.
 
Very minor upgrade in performance using the XC3 VBIOS https://www.3dmark.com/compare/pr/645547/pr/542809#
 
Using the XOC or Kingpin VBIOS was still getting heavily power limited. But I did see one very brief spike to 506W. Since the hybrid will keep the card cooler (hopefully), I'm going to try out the XC3 VBIOS for gaming and see if it helps any in CP2077 - on air it got up to 78C on air with 100% fans.

I would love to get a hold of the EVGA GeForce RTX 3090 FTW3 ULTRA HYBRID Bios if you can upload them?

it's on page 1 bro...
 

Those are FTW3 Hybrid bios and I need FTW3 Ultra hybrid bios
