Big update: I don't know what the computer shop did but my temperatures are now hovering at 55c and 21-25c idle. Junction is at 102c gaming and highest hot spot was 71c.
Mem temps were in mid-high 70s. They only changed the thermal paste to a better quality and dropped by 3c AFAIK.

I put up two Thermaltake Toughfan 12 on the radiator with the hybrid ones on the other side to do a push/pull and have the case set up as CPU radiator exhausting top and GPU exhausting side with SL120s intaking at bottom.
 
Edit: Furmark now shows junctions now at 110c MEM1/2 and GPU 2 were reaching high 80s with all fans maxed out leaving core at 48c. On idle MEM/GPU2 run in their 40s. Gaming so far MEM appears to hit high 70s and junction slowly builds to 100c after being in the 90s after awhile.
Should I really go for a vertical mount if it can help cool down the MEM and GPU2 temps?  (LL 011D case)
 
Lastly I'm having trouble where the memory fan is ignoring manual set speeds on ICX, it'll stick to the manual speed but eventually control itself regardless if 'auto' is off. (Fixed after bios update)

Your icx temps at idle (assuming cold idle) are good bit warmer than mine which are in the mid 20's and the mem temps are 20C more than mine in furmark.  I've got 7 fans intaking into the case, 4 of which are the front AIO fans (CPU at low power in furmark) blowing lengthwise on the card. 
 
You don't have any fans blowing lengthwise, so maybe vertical mount if there is air flow at the card's back, or maybe a front grill where you can mount fans.  If it was me I'd get some perforated metal (PA speaker grille material) and fab something up.

Overall it sounds like a good improvement, glad you stuck with it.  My mem junction temps were above 100C when I was top intake and the warm air from the rad was blowing on the back of the card.

His case has full glass front, but the way he has his rad setup means negative pressure, maybe he could try setting gpu rad as intake, since warm airflow is better then none :/

Yeah just updated my post above, my mem junction temps were above 100C when I was top intake and the warm air (~35C) from the rad was blowing on the back of the card.  So figure mem junction is going to be about 65C-70C above the temp of swift air flow on the back of the card, even though the chips are cooled directly on the front by the cold plate on the hybrid AIO and the main temp is about 55C.  My interior air is now just slightly above ambient 20C, with the CPU barely working in furmark.

I'm not keen on doing custom work to the case for now. The negative pressure placements were at the suggestion of a second computer shop with them explaining it'll exhaust all the heat out despite me pointing out online suggestions (not just here) that CPU radiator side intake would be beneficial (GPU currently at side exhausting). I have vertical mounted now, playing Mirror's Edge: Catalyst does increase core temps to 60-62c vs 55c before as the shop predicted the mount would do. Junction temps were very slowly and steadily increasing to 100c but it maxes out there with it dipping fairly quickly so there's improvements to an extent. Hot spot was 76c.

Wish I could cool down the GPU2 further as it still hits 80s and other mems hitting high 70 but I guess there isn't much to do there apart from custom looping.

DO NOT NEED.
 
SHOULD NOT QUE.
 
MUST RESIST URGE TO QUE

This auto-notify button should expedite things on the registration effort tomorrow (no guarantees, of course, but it was the correct link last time):
 
3090 FTW 3 Ultra HC (3989): Auto-Notify Link 
 
As a reminder, it likely won't go live before 10 am PT tomorrow (maybe 9:59:58 am PT). 
 
Best of luck!
 
Edit: FYI this is the same link as CptT95's a few posts down.  Either will work.

I scanned through a few pages of this thread but am unclear. How are the memory temps on the 3090 FTW3 HC? Junction temp.

It looks like it has a swiss cheese backplate which doesn't look effective for cooling the rear vram and not very conducive to heatsinks either.

also the swiss cheese is on the end of the card near the power ports, not where the mem modules are lol
 

my bad, didn't realize just how fancy they made the HC backplates with holes lol, its a full cover waterblock, though how that cools the back I honestly dont know; thats a question for the engineers I would think :/

if you are truly worried about it, then buy an Optimus Waterblock for it, their backplate atm is only the XL version with big thermal pads for soaking up the heat lol

Actually the HC backplate is pretty much the same as the air cooled version. It may be better than I was thinking as the air cooled version appears to have fairly low temps. A lot better than my card was stock at least.

Don't know why I'm bothering though. Probably 0.001% chance I could get in on the notify fast enough anyway.

CptT95, I’m on my mobile...is it different from the one I posted yesterday?

I don’t think it is Mr enewt (an early good morning to you). But, I’m on my mobile as well.

Thanks. I’ll get to the computer in a bit and figure it out. Will post before 9 am PT so we’ll have an hour at least to debate it.

Idk if I want to queue for ftw3 hc today or just wait for kpe hc
I signed up for the kp hybrid yesterday thinking that it will hit me end of this year or beginning of next and using an optimus block on it having twin Kingpin cards in sli

Pre-save the link because there is a 100% chance the site will still go down for a few minutes:
 
Good luck to those tryin' to get one:  24G-P5-3989-KR

I assume those links flat out don't work until the button is live?  Because right now they lead to a main product list page.
