I get the same thing with my Zotac 3090 and the Corsair reference block. Insanely hot backplate but the card runs along nicely at 52 to 55c compared to the mid 70s I was getting on air.

Not necessarily - if you have a good thermal coupling and the backplate is cool, it shows you're dissipating the heat more effectively. If the backplate is hot it stops being an effective heatsink - you need a delta T for heat transfer.
My rear fan is an intake and blows directly over the backplate, which obviously helps. I've now installed the Mp5works too, because I couldn't be bothered returning it
Was just watching EK livestream, they teased 
at the end of the stream the 3090FE block. Looks to be identical to 3080FE block but bigger to account for larger PCB. Not unexpected. They did mention the backplate cooling earlier in video and if that is what caused delay of the block, but seems that its not needed. Seems the thicker grooved backplate should be sufficient. Did also come with both flow through options. Pre-orders up this month then shipping next month though imagine need to be quick to be in first wave!

No idea anyway it appears this is only for the reference block atm so no use to me with my FE.
Wow really? If thats true thats taking the ****! I rather just slap a ram block or get other brands for half the price, even more so with ram blocks which can be had for cheap.

The backplate on my 3090 block is burning hot, but Im not prepared to pay a for a the equivalent of a full block again lol. Might just get a big ass heatsink and thermal pads to help

Thinking the same haha but i have a watercool block in transit shortly so see how that copes. From the manual i've seen so far they use thermal paste over thermal pads for better contact... its rather messy though.

This is WITH a EK waterblock and backplate
Get those weird little aluminium fins you can buy in big packs and stick them on haha.
What temps are the VRMs actually reaching with stock backplates? I know people mention its hot, but no specific component temps.
It really looks like the took there normal FE block and put it all inside another shroud to me heh. Wonder what that key on the bottom is all about. Seen its up on there site though, 9,150.00 TWD / £240 (excl shipping and VAT) vs 4,500.00 / £115 (excl shipping and VAT) for there normal FE blocks.
Bitspower blocks for 3080 FE are dropping!
Looks like a little USB stick lol

I saw a post over on the EVGA forum where someone installed a ram block to counter the heat, the reported heat output on the stock backplate was touching 97c. Its totally believable as its burning hot, i wouldn't be able to hold it there for longer than a few seconds.
RGB connector?
Ah yes it is, i can see it now haha. Tbh i thought it was a pressure release valve for easy filling haha! Let those air bubbles escape.

Is obits a water cooled USB drive?
Yeah...My EK mystic fog fluid became...almost clear after a week that it spent in the loop
After communication with EK, exchanging all the details, they told me it was bad batch. Don't really see any build up of particles in tubes or blocks, so not sure what happened. I guess bad batch happens

Well I finally installed the Bykski which I brought for £60 from AliExpress during the 11/11 sale. It took 11 days to arrive. I wasn't charged any custom fees because they put the value as $44 :3
I have the 3080 FE, but they rushed to be the first to release the blocks and mistakenly etched 3090 on the backplate
Installation was a breeze however the instruction were very bad. It came with 30 screws which confused me a bit and I ended up using only 12 screws. I also had to buy the Gelid 3mm Thermal pads so the board components can make contact with the backplate.
I was using a custom curve of 881v 1850Mhz with the Original Cooler and would get max temp of 65C while playing Red Dead. Using this block with the same curve it reaches 40C.
