I will run the water loops without the PC on, until I find that sweet spot, and it may take me a couple of weeks to find it, and get it right. than I will turn the PC on, and start adjusting the hot side loop fans and water flow rate so that my water does not get to cold to run the PC.

well, I do agree that the system needs to be a high flow system, I achieved this with the parallel design of the water blocks.
no internal modifications are needed to be done with the water blocks with this design.
the flow rate on both loops will be from 6LPM to 9LPM and the cold side will be at 9LPM, if not over.
 


Your parallel flow design does not change what a CPU water block is designed to do.

It is designed to pin point and focus its flow directly over the CPU core, forcing it through a pin grid over the core area, and running a parallel flow design will not change that.

We are not talking about cooling CPUs here which is what a CPU water block is designed to do, we are talking about cooling peltiers, and we are also talking about collecting the cold produced by the peltier as fast as possible to get it away from the peltier to avoid stalling it.

A CPU water block can only be used if you remove the core focus and allow the coolant direct access to the entire copper base plate of the water block, which is exactly the area the peltier occupies.

Do you think the peltier is only going to produce heat or cold in it's center?

on the test build, I used a MCW50 water block for the CPU, and two MCW40's on the TEC, these are high flow water blocks with a open design, they allowed both the hot side, and the cold side water loops, to flow at 7LPM. so I do understand that a lot of water needs to move past the TEC's all the time for them to function correctly.

things change with a parallel design, I tried to show this with my parallel setup.
with a serial setup that modification was needed to achieve the desired flow rate.
 


The Swiftech MCW series are GPU water blocks, those are not the water blocks you have pictured in your build?

no they are not, I used older swiftech blocks to test how the TEC functions.
I needed high flow blocks, for my test build, because it was a serial design, on both the hot side, and the cold side, as I was only using one TEC.
on my serial vs parallel, what I tried to show, is that with the same hardware, I could achieve almost twice the cooling ability by paralleling the system.
the same applies here, I can collect almost twice the amount of coldness produced by the TEC's, by paralleling the loop, when compered to what a serial configuration of the same hardware could do.
this is why people call BS on my parallel setup, so what, that is there issue, not mine, I did not do it to cause issues, I did it because I knew that my system could cool better, If I got the design of the system correct to get the most out of the radiators as possible, if others would like there system to cool a little better, maybe one day they will give it a try, and see for themselves that it does work exactly as I have shown.
 
OK after tracking down the CPU water blocks you are using, you confused me by saying they were MCW40s and the MCW design is Swiftech which all MCWs are GPU water blocks all side ported inlet/outlet water blocks.

You could have easily clarified that by posting a link to the actual CPU water blocks you are using which are the MagiCool Black Butterfly Universal fit CPU water block probably the cheapest water block on the planet and for good reason, because they absolutely completely sucked at cooling the CPU when compared to other water blocks!

However that was because the inlet did not force the flow ported directly over the CPU core, which by the way, pisses me off!

If I had found those sorry ***** water blocks I would not have had to modify mine!

The flow rate is exceptional because there is zero core focus restriction, like the Swiftech, XSPC, and EK water blocks have in their design.

You can clearly see the pin grid through the inlet and outlet holes.

So that concludes my curiosity with any needed flow modification of the water block, now finish that freaking monster cooling of yours so we can see what it can do!

I recently had to sleep next to my pc (long story), my head was literally a dozen cm to the left of the case and I can see the appeal, besides, it means you could put the monitor on the opposite wall and be able to game without even having to get up. However, I warn you now that if you make a build log, I will post every dirty joke I can come up with.

since we are on the subject of work, I did have a question about this build, for 4ryan6, if you where to put all the time together used to create this TEC build, minus the failures, about how long do you think it would take someone to duplicate this, working at a couple of hours a day?

moto I am really looking forward to the build log on the bed, my mind has gone to a really wrong place, too many times already. :lol:

 


ArthurH did duplicate the build from scratch and it seemed like it took him a week, but he invested more than 2 hours a day though.

Since I know exactly what I am doing I could do it in maybe a couple of 8 hour days, 3 days at the most, the most time consuming thing is modifying the water blocks.
