I'm still in the mono block camp, however if we do go dual blocks, what do you think about doing what EKWB does with their chipset blocks and extend them up past the 1st PCI-E slot and have the inlet and outlet next to the CPU socket?
 
Just a thought for those who might not have their gpu in the loop or possibly make loop management easier.

There is 0.66" between the socket, and the retention clip of the PCI-E slot.  My O-rings are 0.0625, so I would have that on both sides so that would bring that down to 0.535.  Not saying its impossible, but everyone would have to use the same CPU block so I can ensure mass compatibility.  There is 0.783" in between the CPU post and the PCI-E slot, so a 1/2" bitspower type fitting CAN fit in there, but depending on the CPU blocks used could render putting the inlets there would have to have the thinnest channels I have ever done.  There would be considerable restriction.  There is 0.986" in between the PCI-E, and the RAM slots.  
 
Also, if I had water passing over the motherboard hole, I couldnt use that hole for mounting, so it could only use the 2 holes by the south bridge.  That would be a tremendous cantilever mount.  Since motherboards tend not to move, there are ways around things, but generally I will discourage that particular design.  

Fair enough nateman, in that case, that sounds a far too restrictive design and really not worth doing.

Incorporated a CPU block into it.  

 
Now comes the hard part, the sandwich plate to bring them all together.

Can't wait to see the final product tbh :D
 
On a side note, I have tried using some passive heatsink to cool the M.2 drive, but on Crystal Mark it still heats up for 61C.
 
Do others get similar temps?

The range is higher than that.  Some SSDs can get to 90c+.  I think they'll just throttle if they ever get that high anyways.  Those temps you have shouldn't be too worry some.

sounds like i have to cool SSD.  That is way too much heat for any component.  

The Z dimension right now is my enemy... so i really dont want to touch the SSD.  I am merely stating that is "possible".  The time is already racking up.  I dont charge by the hour, I charge by the job.  I do this for fun and the challenge.  The sandwich block is shaping up nicely in CAD and its getting more complicated, but the mono block can be done.

I think it looks brilliant!!

Could you use a 1/16'th inch end mill? What rpm dose your mill go up to??

What I'm concerned is with the block installed and GPU watercooled, the air flow to the M.2 slot will be greatly reduced.
 
That will translate to a higher temperature of the M.2 drive

The hot air from your GPU's will cause overheating. Removing that hot air by watercooling may reduce the air flow over the m.2, but if you have positive pressure airflow, then your m.2 will be fine.

Yes, they can get hot, but keep in mind they are meant to go in the back of laptop or into a tablet, and they don't have ANY airflow at all and get more abused as the only storage device.

How can they survive in a laptop with zero airflow if they can't survive in between watetcooled GPU's?






M.2's are not so bad that they overheat and die just because they are in a pc rather than a laptop.

Having the m.2 covered by a piece of copper will extend the time and cost of having the block created, and i dont think it is going to do what you think.

If you aren't Benchmarking the drive 100% of the time, your m.2 will be fine.

This is what I mean about end mill geometry.  The purple bit is 1/64", and the mammoth gold bit is 1/16".  The shaft diameter on both is 1/8".  It was deep enough to get some depth, but not nearly the 0.72" needed.
 
 So in order to compensate we either have to accept the cross sectional area of roughly a 3/8" pipe, or go "outside the box" and go above it by adding more height to the slot.  Since its such a short duration where the liquid will accelerate, I honestly think it will be fine.  I will try and eat away some of the extrude, it just wont be deep.  I will carry on my  wayward sons...

The sandwich (probably should call it manifold, but I am hungry so it will be called the sandwich block) is starting to look like it has the measles.  
 

 
Some of the holes are through holes - to pull the copper blocks into it, 4 are the CPU holes, and the rest are blind holes, which the top plate will screw into.  Some of the tolerances are crazy, and since this is plastic i am screwing into, each hole will need a helicoil in it.  
 
Next pic should be the top plate (the one you will actually see) so the holes will be cut down some, but you see why I opted to make optional vanity plates for the stinger blocks.  LOTS going on here.

And finally, here is just the required screws to hold the plate down and waterproof the unit:

 
here is what it would look like with a vanity plate:

 
The holes in the vanity plate can me made to fit whatever fittings one has, and the CPU holes are what would keep it all together.
 
I will start working on some prices, so shoot me a PM when you want that news.

I like the idea of a mono block.  Any chance of making it with a clear acrylic top?  would be cool to see the fluid after adding some LED in there to light stuff up in a case.   
 
M.2 looks cool but I agree it can be cooled with a few heatsinks itself.  

 +1 for a clear monoblock, and I do not need the M.2 cooled.
 
Edit- it looks brilliant!

I haven't been ignoring anyone's emails/PM's about the block, I have just still been brainstorming.  
 
I solved one problem, but noticed another one that will all but kill the monoblock design.  If you look at the last picture I posted, you see how thick it is right?  Remember I said Z is the enemy right?  I perfected a design that works from the top down, but the minute you try to put a video card in the PCI-E slots, it will never work.  The height of the area that cools the south chipset normally accepts 1/2" thick MAX.  That has been my standard for years.  1/8" thick copper, and a 3/8" thick delrin topper.
 
I would have to reduce the height of the area over the south, but if you look at the heights of the board, this will all come down to the sandwich block & the topper.  There are different heights to take into account.  I only have a 3 axis CNC.  If I could 3d print some delrin, a 5 axis CNC, or injection molded plastics then things would be different.  I would have to use 2 thick layers of delrin (the top and the manifold) and by material removal, make them mate together.  
 
I have yet to see any waterblock make a 3d shaped groove for an O-ring.  All of them are 2D, so I have to be very creative.  All the O-rings you see are simply 2d inserted into a groove that was milled out.  I would have to mill along a Z axis (z is my enemy!) and have a contiguous O-ring going across 3 dimensions.
 
This would BY FAR be the most complicated block and the costs would go beyond if I can even pull it off.  
 
On the bright side there is always 2 block designs.  I can make just the VR/chipset block, or monoblock CPU/VR & chipset block.  

Really appreciate ya effort, but can we just stick to 2 blocks?
