Got speed, condolences. I also had a burnt smell from the power area on my 2nd kingpin when it died. It was very random and without warning. Very frustrating needless to say. You will get back in it. Sorry for the wasted time.

Thanks bro, It was a long weekend trying to get this into my system and then having to tear it out and prep it for RMA service.  I also had a new build that I needed to get done in the Lian Li O11 Air Mini on Sunday so I really didn't need a gpu failure to add to my issues.  I spent a lot of time trying to get a vertical mount to work in the O11XL with this large block but couldn't get it to work out as well.  Ended up mounting it horizontal but now have some other plans to see when it comes back to get it in again using the vertical mount.  
 
I hope my RMA Kingpin will be better and last longer than my original.  All it has to do is last longer than 5 hours of use.  I don't think I'm asking for much.  
 
Be safe brother.

How hard is it to cerakote something white. Should be the same as black. No difference. I’m starting to think white and silver has a staining issue when used in a loop. Black is easier to hide this. Probably why they stopped the production of white and silver. I wished they offered nickel plating. Is Cerakote porous? Maybe they need to spray on a clear coat.

I'm not an expert on anything, but I'm thinking that some how the new blocks are either allowing moisture to escape the block or it's allowing condensation.  I have the FTW3 Ultra block in their nickel finish and it works fine after months of use.  The only difference in the blocks beside the original design of the two is the Cerakote finish unless they changed sources for the gaskets.  I honestly don't like the textured finish and I'm wondering if that is part of the cause.  My block passed the pressure test, but that was done under air and while the block/gasket were new.  I've seen some pictures of the white gasket getting discolored on overclockers and I'm wondering if that is having other effects like hardening  which may allow moisture to escape due to the textured finish.  I've seen also a picture on overclockers of one user with a white block with blue colored coolant which looks like the blue coloring is escaping the sealed portion of the block and getting to areas outside of the sealed coolant area.  I haven't seen the block in person, but it appears that the coloring is escaping from a pretty wide area all along the gasket.  The user confirmed that there is dye in what he wipes away so it has to be coming from the sealed portion of the loop.  Here is the link with the picture and his post there:

Some of what other posters there can be attributed to the plexi making contact with the cerakote finish as I've seen that in my block prior to putting through fluid into the block and tightening up the screws that secure the plexi to the block.  When contact between the block and plexi occur it made it looks like a foggy white area around where the screws are (in my case the block is finished in cerakote silver).  But the tell tale one is the user who used blue coolant.  I'm not sure if he tightened down the screws that secure the plexi to the block and maybe his was one where it was tensioned properly from Optimus, but either way it's a concern as my cold plate was not secured properly when I initially received it and had to chase the leak which took me to the cold plate.  After I secured the cold plate properly it held air pressure from my EK tester for over an hour at .75 bar.  When I put my block into my system it the entire system held .75 bar for over 4 hours (I forgot I was testing while I was watching tv).  
 
I'm not saying yet that the Optimus block caused my failure as there was no signs of leaking on my block, but when I look at some of the pictures of others posted on overclockers I'm starting to get concerned about the reliability of the block and gaskets.  For those who use test benches instead of traditional cases it's a lot easier for them to monitor for leaks and condensation.  Once these blocks are in a case, it gets a lot harder especially if they are vertically mounted.  
 
Cerkote finishes used for firearms seem to hold up well and I haven't seen a staining issue with those.  What I'm thinking is that because of the textured finish it's allowing dyes to cling to the finish in the texture.  I bought a white block for the 3080 for my son's pc and after seeing these issues I might be second guessing myself on using the block on his GPU until I know for sure that the finish and gasket are not causing issues.  I don't think you can clear coat over the cerakote as it would defeat the purpose of using that finish.  
 

Whoa. Just went through the link. They need to go back to nickel plating.

Yup, I have the same issue, even though the air pressure test showed no leaks.  I have the matte black finish (a replacement for my original nickel finish, which had major leak problems that I could not resolved).  I removed the Optimus KPE block from my system.  I e-mailed Optimus.  Hopefully Optimus will not take weeks, months to reply.

Do they charge at order time, or at shipping?

At order, which really sucks for those who pre-ordered in July 2021 and have not received their order.

The downsides of participating in a Kickstarter...wait, what's that?  This was an previously formed company that took preorders for something that didn't have a final design, changed the finish options after preorder, provided very little updates, still hasn't fulfilled their initial preorders, and is potentially having some production/performance issues?  Sounds like a Kickstarter to me.

Exactly, and had this been a Kickstarter, I would have expected these issues.

Does anyone have a HWInfo 64 screen print of a 20x PR stress test with a KP optimus block installed at stock offsets?  And their ambient + coolant temp?
 
I flipped through the last 20ish pages of the OC.net thread and saw some nice looking systems and a few GPUZ and HWInfo shots but they exclude the ambient/coolant temp.  Those that have prints from GPUZ or HWInfo also have memory temps > hot spot temps which I think its indicative of mining as a benchmark rather than PR 20x.
 
Overall, I'm just trying to make a swag estimate of how much money I've wasted 

I could run something at stock while i'm sitting here.  looking for any specific measurements/graphs to include in the HWinfo screen?

redteamgo
That would be awesome, thank you!!
 
If possible, I'd just like to see the below screenshot section from HWInfo64 after a 20x PR stress test with a Kingpin 3090 mounted to an Optimus block that also shows the peak coolant temp and your swag of the ambient temp at the time of the test.
 
This screenshot is just an example of what my HWInfo GPU section looks like currently and I highlighted my coolant temp
 

OK, I'll see what I can do.  I had an ambient thermal probe at some point.  Doesn't appear to be connected anymore.  I'll get my laser thermometer and measure a couple of surfaces.

Nevermind, I'll have to try it tonight.  It won't let me KVM over to my other PC while I'm running PR.  Just exits out when I switch.

So I have this data for my EVGA FTW3 3090, air cooled and then using the Optimus block, I plotted it in Excel too, so there are pretty pictures. I know it is a different block and a different card, but may give you an idea on what you could be looking at for the KPE block?
Here is the link to the thread where I posted it.

Its is post 13 in the thread. 
Actually, looks like i never posted back with the waterblock results. I have those graphs too if you would like to see. 
 
Anyway, here they are: good results from Optimus... this is why I am convinced that the block is worth waiting for.

I'm an excel guy too lol.  I'll let you set your own bar of madness.  I have logs and excel comparisons of every mount I've done
 

Are we doing this at Stock clocks ?

fragility, thank you so much that is perfect.

On a side note, I did find a bunch of crud is caught in the fins of the Optimus block, so may be impacting flow a bit.  It's fine enough to be acting as a good filter!  Now it's bothering me, so going to tear the whole GPU loop apart and clean and flush everything.  Not likely a huge impact on temps, as the flow appears to be decent, but I just had the pump on the GPU loop fail and now wondering if some crud got in there.  I'll run another test before I tear it apart with a small OC, the voltage slider cranked, and fans on full throttle.

The Optimus fins are very fine indeed - I purchased a Signature V2 CPU block from SpareTimePC before he left us, and when I opened it up it had some crud that the fins basically filtered from the coolant - I believe SpareTimePC had never used colored coolant on it either. Cleaned off easily.. guess it's better than building up inside the pump. On the subject of filters - there are plenty of inline filters available if so desired (link), I like the look of this big Aquacomputer one (link) which has 2 integrated valves so you can clean it without draining the loop. Great idea.

Hey , I have been following this thing for months and so glad we are now talking about a product .
I have the KPE block but was too chicken to install it and currently in 2 AIOs 
These are my current numbers on my undervolt  (.935v +108 PT +1130 MEM  +Fan curve at 36db @ 1foot) .. Just for comparison proposes so others can follow and make up their mind on what they might try to do :NVIDIA GeForce RTX 3090 video card benchmark result - Intel Core i9-12900K Processor,Micro-Star International Co., Ltd. MAG Z690 TOMAHAWK WIFI DDR4 (MS-7D32) (3dmark.com)

I am going to build a loop soon but these are my chicken scores!
 

What?! you have the block and haven't posted pictures yet? Damnit man, what's wrong with you?!  Just kidding! Just take the plunge, you'll be fine. That's a little toasty, but not too bad at all. I think if you can keep the GPU in the 30's with the waterblock you'll see some great boost clocks. I think the rear cooling plate will really make a big difference.

So anyone else in OP5280 to OP5290 range got their shipment notification for optimus KPE block? Seems like the latest appears to be OP5270 from couple pages back

I’m in the 5290’s. Optimus said mine will ship in a few days.
