a lot of times the best solution for backplate cooling is simply 1 or 2 120mm fans blowing directly on the card. i use this a lot when benching since i have a few fans sitting around for cold runs. when i'm not running cold they make good backplate coolers

My delema is do I use the OEM backplate or the one they send , it's plain steel I think.

Looks good! So much better service as compared to Optimus concerning new releases.

Right but it's worth the wait! The quality of the two is night and day. I have both so it is pretty easy to compare. The EK works fine but feels like a toy compared to the Optimus. The nickel plating on the EK block is already starting to show wear after a year.

I'd really like to support Optimus if they could get their act together, but the delays and lack of new products is a disappointment.  They don't even have 3090ti blocks, so they are really out of the running as far as anyone with a 3090ti is concerned.
 
"Optimus July 2022 update:  3090 Blocks, 3-4 weeks delayed"   Like what?  =/   Why are we still seeing these delays?  Most of the PC hardware/supply chain/inventory industry wide issues have been resolved at this point.  I'm sensing the company (or this water cooling division of Optimus) is having issues or PC water cooling isn't a big priority for them.  Which is all unfortunate because I agree with you that the quality is there.

I bought vector 2 for my 3080 and this cooler is heavy, with both side installed and you can not just do one. Also found out that it is taller then the air cooler that evga already supplies.

Actually it is one of the lighter ones. My Optimus waterblock is over twice as heavy. Yes I have both.

I ordered the one sided version

It's out for delivery today,

im so jealous!!  I hope i have the same luck.  I ordered mine last night and hope it can arrive before august 17th like it states...  Ive been waiting for months for a waterblock for this damn card!!!

The big question is what will it do for temps (compared to for example the Hybrid cards).

Has everything to do with the loop, I have an EK 360 Se and a 360 PE , a 12900k 5.2 all core at about 1.316v . I plan on slipping in another 360 se on the side mount and it's going to be tight. My Kingpin HC Delta is about 17-20c , I can pull 600w + on single runs but only about 470w max on overclocking and that puts it in the low to mid 50s, my undervolted/OC KP pulls 407w average and is about 4% faster than stock and can maintain mid upper 40s on heavy workloads. Anything I change in this loop or power settings affects everything. Looking to see if it's a silver bullet is just not to be expected, The fins are finer and there is a jet plate design that should provide better cooling than the HC blocks, we just won't know until I run it. The backplate is aluminum and not quite as thick as a KP , but they provide a whole set of pads, more than OEM , for the backplate. I hope it's great but it won't be apples to apples comparison.

The backplate won't matter much with all the mem on the front. I fully padded up the back of my 3080ti in the Alphacool block. Backplate only gets a little warm and putting a heatsink on it doesn't appear to even nudge temps. I think the key is to use premium pads on the front.

For reference in regards to loops. I was playing Forza last night with the 3080ti pulling about 500w. Core eventually hit 45C when the room got to 26C from all the heat being dumped out of the loop. But I have dual D5s and 4 rads. Two CL480s, a 360, and a 280. CL480s are external. Block delta was showing about 13C.

That's probably about 20C lower than the hybrid cooler could manage even with some fairly loud ML120s running in push/pull. That was just a 240 rad though. Was good to see EVGA went to a 360 for the 3090Ti.

Ya, thanks for the info, hope the EK pads are good quality, they are all 1mm on the front and I have KPx . I also was going to put a MP5 works BPC on the backplate, but if it's only warm to the touch , it won't matter much and would get more mileage out of a fan.

EK thermal pads are good enough. On my ekwb 3080 ti FE block (using 1mm pads everywhere), the difference between Gelid GP-extreme and ekwb pads is around 4 degrees on memory (from 52-54 C using ekwb to 48-50C using GP-extreme). Although I have to say, it is much harder to peel the plastic sheets off on EK pads...

The trick I use is to right click in imgur and open the pic in another tab.  That gives a usable address.  I think you may be able to right clock and copy image address too.
 

I got you , I did it once but forgot, lol thanks

Jesus I cant wait to get my hands on this block!  Really hope I can game @ 2200MHz with it

I was kind'a hoping Nereus would beat me to it, I will drain the loop and put it in in the morning, see you next time 
 

Its IN ,  did not have the patience to put in the third rad, so I am on the same system as the KPE HC, first PR run it was about 6 C cooler than the HC flat footed stock (418w KPE , 438w 90 TI ) AND<< left off the RGB cable , not a header or cable I could reach without tearing it down

1 360 SE  and 1 360 PE radiators , fans 60 %  , D5 @60% , 
just did a boosted PR run 15508 - +155clk +701mem , clock was a steady 2190 (which is where my old KPE would crash without massive messaging of the classy tool) , average temp 45 in run , 23.5 ambient and the thing cools off when at idle much faster. 
 
SO,  there you have it, any questions?
