With the issues I've had with my block and the slow pace for them to release a fix (not even mentioning the lack of transparency in the process) I'm leaning toward just asking for a refund. I'm not sure I have the trust that their fix will work, and it could be another potential time sink trying to put the block back on and hoping it'll work. For me it really tarnishes them for any future products. I'll keep their CPU block as it works great and after a year or so, no issues, but I don't think I'll be purchasing from them again unless they can turn things around. And these further shipping delays and lack of transparency isn't helping.

I think they are delaying the block shipments because of the issue that you, others and I have with the leaks between the acrylic and front/backplates, even though it alone passed the air pressure test.  I am still waiting on an ETA of the replacement fix shipping.

I hope you're right on that. Every single time I read about these issues I keep wondering if I should just finish my build with the HC Kit I have collecting dust in a box. In the meantime, the KP in Hybrid mode continues to run in my older PC.

OP5300 just shipped out

That’s great! I hope you will not encounter the leak issues that I and others have with the block.

If they are still shipping I would imagine the leaking must be fairly rare and you should be reasonably confident that it is not a given

OP5301 just got fulfilled

Good evening,

After many months, almost a year, waiting for the block. I am trying to mount it on the GPU.

I have some doubts as the instructions do not provide clear enough pictures.

The thermal pads to be applied in the photo provided by the company do not look at all like the GPU PCB.

I think I got them right, could anyone confirm?

In addition the screws to be put in the first step I can't get them to reach the other side (the ones with a length of 12mm).


Any advice?


Thanks!

Best,
Miguel

Yes, your pad application matches the instructions:

 
The first step uses the 6mm button head screws.  Are you talking about the ones that go through the backplate to the main block?  If so, the giant thermal pad is pretty thick, you'll need to compress it a bit initially to get the threads to bite.

I followed the instruction laid out by Optimus and the assembly of the block went together without an issue.  

I would recommend laying out and sorting the screws provided by Optimus.  There are different lengths and quantities.  Each colored screw in the instructions by Optimus fit in my build just fine.  Just be sure to double check you are using the right screws for each step.  
 
Thermal pads I followed their instructions also without an issue either.  
 
be sure to pressure check the component after you are done with the installation though.  

Thank you both! Will compress the backplate a bit more this Sunday which is when I am going to be back at home.

I was worried to press down too much. Also I have used some thermal paste on top of the chokes (R15). Guess it is not going to hurt either 😅

Thanks again will come back with some results :)

My understanding is that flow direction matters for the Optimus block.

Not sure how complicated your loop is but you could run an experiment.

You will need additional support with the Optimus blocks.  Its 6 lbs 3.2 oz (2,810 grams) of machined copper and acrylic per block.
 

 

GOOD LORT !
Did the KPE come with a bracket, I put mine vertical but I cant remember if there is one in the box?

Does the acrylic plate touch the copper plate for both the front and backplate or is there a small gap between the acrylic and copper plate?

It touches.

Bavor,
I think no matter which way you mount it I would consider using multiple brackets to help take the load off either the end in your picture or the PCI slot.  I bought a bunch of support posts from Amazon to try and use once I get my issue with my block resolved.  I got back my RMA Kingpin last week, but I haven't had time to bench test it yet.    
 
When I did mount it in my O11XL, I had to mount it horizontal as the vertical mounts I had created issues related to proximity to the CPU block.  I have the Lian Li XL vertical mount, the Lian Li Lancool vertical mount, and I bought the EK vertical mount (which I could not use due to the rear block).  I used two post under the GPU in the horizontal position to help take the load off the bracket and slot.  
 
I just picked up a bigger case to move my Kingpin into which I am hoping will allow me to support the Optimus blocked Kingpin better once I get my conversion done again.  I picked up a Phantecs Enthoos Pro 2 on Saturday.  I am weighing my options as to how to mount the gpu.  Use the vertical mounts I have, or use the vertical slots in the case, or do something custom now that my case is a bit larger and I am hoping more flexible for mounting the GPU.  I am thinking a custom shelf where the secondary ITX board would go to put some sort of mount there to support the Kingpin.  I haven't had much time to think what I am going to do, but the weight of the card would be something I would want to make adjustments in how I mount this block to ensure maximum life of both the GPU and Mobo.  
 
 

i use a thermaltake core X1 for this reason.  my entire deal is a vertical mount.

I can't use the Lian Li GPU support bracket with my current motherboard even though ti came with my case.
 
With having a bottom radiator in my case, I need to put metal fan grilles over the bottom radiator so I don't have the weight of a GPU support on the radiator.  The other option is to make a hanging support from the top radiator/fans.
 
At this point, I'm thinking of building a stand for my case, so I can put my case on the side and still allow for proper airflow so that the cards only have their weight on the PCIEx16 slot and the rear support bracket.

just get a core x1.  they are cheap.  check my modsrig.

That's a nice case but unless the weight of the block is supported by something else the 7 plus pounds of block is still only supported by the PCI slot or the rear I/O backet.  With the design of the Optimus rear plate not extending all the way to the rear I/O bracket any weight the I/O bracket provides could  compromise the GPU due to flex especially when the pcb heats up or over time/age.  It would also put most of the weight on the GPU PCI slot which although due to the horizontal mounting of the mobo is still something I would not prefer to do unless I needed.  The Thermaltake option is a better option though than having the block sit horizontal and twisting the PCI slot on the mobo. 
 
I was looking at the Thermaltake X20 as an option this past week for my build.  I went with a Phantecs option since it was available immediately for me.  
 
I am hoping to hear back from Optimus soon on my front block issues.  I again am starting to have all these parts and funds expended for my pc sitting around me.  New tubes, fittings, parts on order which include a new set of radiators to maximize the cooling capacity of my new case, mounting brackets to try, etc.
