So this is a project i have been working on for a while and its now complete but have not tested performance yet.  A lot of people were saying there was no way to use the original memory cold plate for the kingpin card because of the way it was designed with any type of water block so i decided to try a modification. I bought the EKWB thermosphere to try just because i am thinking of using the EK-FC Terminal to link two kingpins together if this mod cools good. I like the Hydro Copper block but i wanted to try this mod and see if the flow can be improved because i think the hydro copper is to restrictive. What i done was replaced the thermosphere block with the G92 bracket instead of the G80 bracket it came with and used the standoffs it had came with. I removed the standoffs and then placed the cold plate on the block and then screwed the standoffs back on using them to hold the cold plate in position. Before installing it i drew the outline of the cold plate opening on a 1.0mm copper shim that could be used to fill the cold plate opening after installation.  i used my dremel grinder to then shave away the copper shim to fit inside the opening of the cold plate. After that mod i placed it on the pcb and tightened it down to make sure i had good contact and then removed it to inspect it and the thermal paste spread pattern was excellent and the thermal pads on the coldplate were contacting the memory like they should be.  I decided to go ahead with the rest of the mod then by reinstalling the original copper heat sinks and fan assembly as well as the back plate using as many of the screws as i could and then also added an LN2 kit OLED for the Kingpin so it still has the display screen.  So now that the mod is complete i will have to do my testing to see if it was worth it or if i just did a mod to say it could be done.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

This is very interesting. 

Very nice.. but doing this mod looks like it will void warranty for the kingpin since you had to mod the cold plate. Unless somehow one can get an extra cold plate from evga.

Gona hurt to see the temps I bet! Obviously the GPU temp will be better I'm guessing.

The EK-FC terminal work with this block? Seems the card is too tall and would block it unless there is an option to add it to that top of the delrin adapter ports.

Oh, ok.. hehe tuff to tell but see it now. Be more interesting to know now how much that shim effects the temps. Did ya use liquid metal for tim between the shim and cold plate?

Hope it all works out as people will need this since it looks like they may have finally sold off all the blocks.

Actually if you look at the EKWB site you will see that these thermosphere blocks were made from the Supremacy blocks but just for the use of the EK-FC terminals for multiple cards. The supremacy blocks are really just for a single card set-up.

Ok so its at least installed and running so here is the temps difference at just idle. Just as i figured the memory and vrm's are all about 3-5 degrees warmer since they are not water cooled now, the die temp only went up 1 degree with having the 1.0mm shim on it. During benchmarking is where i'm hoping i can keep the die temp cooler now since its not going to be mixing with the memory and vrm's heat in the block.
 
 

Just like AHowes said, should be interesting. Looking forward to the temps.

Updates??

What are the temps with a 3D load after 30 min? What are your ambient temps?
 
Memory cooling isn't that critical with GDDR6. The max operating temp is about 95c.
 
I went different route with a EK GPU Supremacy block just over the die. Memory isn't covered. I turn the fan on the VRM heatsink to a fixed 80% and the memory never goes over 60c while gaming for hours at a time. The VRM is so over built that without adding voltage with the classified tool I doubt a VRM heatsink is really necessary. 

Well i played several hours of call of duty modern warfare with everything maxed out, and the memory stayed at 45C and the die stayed at 40C. I had the vrm fan at 100% so it stayed nice and cool as well. My ambient temps are 22C   I did not have time to get into any benchmarking before i had to leave for Arizona.  When i get back home i am also going to switch out the 1.0mm shim i used and try with a 0.8mm shim that i have ordered to see if there is still enough clearance to decrease the shim thickness. Its gonna take a while to really narrow it down and see the overall difference in cooling but so far i'm liking what i see. Thanks for other forum members interest in this mod, i'll try and keep things updated as much as possible so you all know whats going on.

So now i have figured out that the EKWB vga supremacy block can also be installed on the kingpin card and still use the original coldplate for the kingpin as well. Just a slight mod to the coldplate is needed.

So i changed my username (dwexpress) to (sparetimepc) on my evga account and after that was done it messed up my being able to get into the forums, they have been working on it for several days now and have still not been able to figure out how to link my forum posts to my new user name after it was switched so for now i have had to just revert to a different account and username all together until its figured out. Didn't know it was going to mess everything up just with the switch of a username. Anyways this thread was started by me as dwexpress and now i'm altonadavid.

Anyways here is photos of the mod with the ekwb vga supremacy, and this mod cools the die about 7C better then the thermosphere because the flow is so much better but the memory cooling is quite a bit better with this vs the thermosphere.. The same 1.0mm shim is used as what is used in the thermosphere.
