Anyone getting a KP HC block, fair warning, it is INSANELY heavy - and I highly recommend hooking up the tubes to it before installing it in the slot (that might be obvious to some but I didn't think it through and it was not fun putting them on there with the card installed in the slot).
 
Must say the temps are nice... but I was also expecting slightly better core temps... but, I suppose that's the price of the RAM being cooled so well, VRAM Temps under PR load are only getting in to the mid to low 30s in the iCX sensors now, Memory Junction maxing out in the 50-54C range.  Yeeee bwoi... and that's with a +150/+1250 OC. 

All the Blocks are heavy for 3080's vs past gens due to the size for sure....no need to try n connect tubes initially (I wouldnt recomend this at all as you risk fvrking up a seal on a compression fitting while manipulating the Card into the PCI-E Slot...just ensure the Card is secured at the IO bracket with 2 screws (although single slot bracket 1 screw is fine, just make sure its tightened right down.... more than enough support......then plumb...rigid tubing will provide some decent added support, Im using flex tube and no sign of sag, however I found a simple way to use a zap strap on all 3 PCI-E plugs (gather them together) and secured to one of my Bitspower fittings coming off my pump / rez for a little added support........SLi was great in that 2 Cards connected with an EK Terminal Block was perfect, very solid......
 
Curious why did you have so much trouble connecting your tubing after the Card was installed ? Rigid or Flex ? If flex a great trick for getting the tube ends over the barbs is to soak the pre-measured piece of tubing in very hot water for about 30 sec...softens it up and will slip right on like a glove ;)....then a little "spit" on the outside of tube, slide the compression ring on and tighten away!
After 10 yrs of building custom loops you figure the "tricks" out ;)

Tubing being stiff because it was fresh cut new stuff was the problem, learned my lesson on that, but then again, I won't be building a new loop unless it's for someone else, for at least 2 years.

So what ARE your core temps like now? And did the block help increase your Porte Royal score? And were you able to increase MEM clock?
 
EDIT: Woops, Nevermind, I see your post in other thread.

I'm so tired I haven't really pushed clocks yet.  When you consider air cooled cards run in the 70s, the block is doing a pretty good job.  Especially in combination with the backplate mods, VRAM is running cooler than ever before, I actually managed to pass Time Spy with +1250 which is something I couldn't do previously with this card if memory serves.
 
I'll work on it when I get up though, plan for the day once I wake back up is get one of my last non-primes to Prime in CS, then push some clocks on the GPU and do some stability testing since 4 sticks definitely makes me kind of have to start from scratch... settings that were previously "stable"ish won't even boot now, F9 boot loop in to bios reset, and all that is is 3800 memory, 1900 FCLK, with higher memory voltage but stock timings.  I may try that again but with the timings raised to 16-16-16-36-52, see how it goes.  I know having 4 DIMMs vs 2 stresses out the memory controller a bit more, perhaps bit higher SoC will help too, I only went up to 1.125V for trying to run that before I just went back to 3600 RAM/1800 FCLK because I wanted to run some benchmarks already.
 
Overall I'd say I'm pretty happy with it though, memory junction temp being that much lower is a big one because I really do think thermals were holding me back on my VRAM clocks - we'll see though.  The higher boost bins being hit because of lower temps on the GPU is making me have to start from scratch on Offset OCing too.  It's hitting higher clocks at the same offset as before now so while I used to be able to hammer +165 down Port Royal's throat for repeated runs with no issues, now it fails within the first 15 seconds because it's trying to boost 30-45MHz higher than it used to.
 
I do wish I'd swapped the paste, I did swap the VRAM pads that were on the block to 12Wm/K ones because I don't trust eVGA's pads after seeing what they look like when they're falling apart - but I'm not taking it apart just to do that, far too much work for what would maybe be a 1-3C improvement IF Kryonaut is better than whatever they used. 
 
I'm off to sleep, after being up for almost 24 hours on 6 hours of sleep, what a stressful rebuild, but I'm overall pleased - especially with the whole "zero leaks" part of the whole deal.  I also had someone help me move the case on to it's face then it's back to work the bubbles out of the radiators more quickly while leak testing, lines are already bubble free, res still has the usual small ones in it that will work out over time.
But not having random spurts of bubbles shooting out of the 480mm radiator for 2 days after assembly is nice!

@Dabadger84, what kind of pads did evga include? Thickness wise. Thinking of buying some Laird HD90000 or Fujipoly bulk, and would the specs would be helpful, thanks!

2mm for everything as far as I could tell.  I replaced all of the die-side pads for vRAM with 2mm 12W/mK, left the VRM pads alone cuz they don't run that hot to begin with.  And of course there's a whole thread about the extensive ridiculousness I've done on the backplate side to help cool that side of the card.
I don't know what brand it is, it's the gray type that has more texture to it than normal (and falls apart very easily, half the pads I took off the GPU when cleaning it off before putting the block on fell apart and I was pretty gentle with them).

Just got my notify email and purchased, I was 10:00:11

Congrats that got their notify. Still bummed I got an error on my first try...

Got my block before I got my card lol. 10:00:07

Well that was quick

Got the email 4/29 about 3 PM PT. Ordered!

Mine was at 10:00:28, no email yet, so it's somewhere between 22 to 28 seconds now

04/23/2021 10:00:20, got my email as well.

Congratulations everybody. Still tracking reports, but it sounds like we are at :21 at least....

10:00:10 purchased!

10:00:18 purchased! Woo!

:18 wow I want to kiss you. That's a chunk that went out today, that means I could be at the bottom of the next, or next next batch.

10:00:25 still no email but we're getting close!
