ok, so i figured out what was going on with my switches for the TEC's i had a bad switch and because the system shares the same ground this grounded out all of the switches. doh.gif
so , yea i am a not so smart, but at least i was smart enough to test the whole system again, find the issue, and fix it. so, yea for me. wheee.gif
the reason i checked the would system again, was because when i wrote that the LED's would blink on for a sec, as i turned the switches on and off, well that just did not sound right to me, so, i when through and checked it out again.

-30c seems promising, even if it is with no load!

yea, i was a little surprised myself, with my test build it got to -25 with no load on the cold side, but that was also at 16V. also with this build i am able to keep the hot side a little cooler by 5C, so that is most likely the reason for the lower temps. so, i am hoping that i can keep my water temps at around -10C with a load on the system. if not, i will go ahead and build a second TEC assembly, and add three more TEC's to the system. then i will see where that puts my temperatures on the cold side, with a load on the system. it's all trial and error with this build but i will get there eventually, one way or the other.

ok, so I went through and did a complete cost out for adding a second TEC assembly, DYI reservoirs, switches, relays and all the fittings that go with that. the reason for this is if the cold side water loop does not get as cold as I would like it to I am planning on creating a cascade water chiller to the system. that means 6 more CPU water blocks, 3 more TEC's, another 3-way set, of DYI reservoirs, 3 more relays, 2 more water pumps, and the assembly for 3 more switches. after pricing it all out, that comes to a $1000 upgrade for the build, but I want below 0C water temperatures going to the components, and I will get there no matter what it takes. so, if this does not quite do it, I will start the process of building the second TEC assembly water chiller, to the system, and configure that as a cascade water chiller.

what is that going to look like on the build?
here is a sketch.

now regardless of how the build runs at this point, I am going to use it as is, until I have this cascade water chiller upgrade completed.

ok, so what am I looking at here?
remember how I stated that this build would be a thermal dynamic nightmare, well here is a good example of that.
if you look at the pic real close, there is that small section of clay that is really white. now that section has created an air tight seal around the entire hot side water block. this area was created by the clay melting, than cooling down, then melting again. by doing this process, over, and over, about ten times, the seal becomes better, and better. that small section, goes all the way around the hot side water block at this point, and the clay has become slightly hardened in that area, as a result of the clay melting and cooling. the TEC can now run for hours, without stalling out at all, on any of the sides of the TEC. I also think that this is one of the reasons that the TEC's can get so cold now. when I first started running the TEC's, only two of the sides would get cold, and the other two side would stay warm. now, because of this air tight seal going around the hot side water block. the TEC gets really cold on all 4 sides, including the side with the wires.

ok, so thanks to LiamG6, and his great link to the 24/7 Sub Zero Liquid Chillbox Club, I just became there 5th member.
there is a lot of good ideas in there, that I plan to incorporate into my own build, as the years go by. Don't really know why, but I have never looked up, or though of this system as a chill box. but that is definitely what it is, so if any one is interested in creating some really cool looking chill boxes for there TEC builds, here is the link to that club.

ok, fun fact, about parallel setups.
in this picture there are two flow meter in the water loop, one just after the CPU, and the other is just after the reservoir. when starting the water loop up after being off, about one out of thirty times the water flow through the CPU will actually go backwards, when this happens the total flow rate on the system drops by 3 to 4LPM. so, it is easy to identify when this happens, and it is easy to fix, just shut the system down, and restart the water loop. I have never had it happen twice in a row.



I have also had the same thing happen with this parallel setup, about one out of thirty times that I have started the water loop. the water will run backwards through the top water block. I don't have a flow meter on the water block to absolutely positive that it is the top block that is running backwards, but I am making a educated guess based on what would happen with the other setup. I noticed this because my total flow rate after startup was sitting at 6.2LPM on the loop. so, I shut it down, restarted the water loop, and the flow rates where back up to 9.5LPM for the water loop. so, it is easy to spot, and easy to fix, I just don't know enough about fluid dynamics to really explain exactly why it happens in the first place. I just know that it is possible, for it to happen.

ok, so a couple of issues I should have seen but really did not realize until after the build was complete. one, I should have used a humidity gauge like this one.
https://www.amazon.com/Pawliss-Digital-Terrarium-Thermometer-Hygrometer/dp/B017Z7Y6FK/ref=sr_1_33?ie=UTF8&qid=1468319862&sr=8-33&keywords=humidity+gauge
that way I would not need to start up a second PC, in order to check the humidity inside the ice chest before startup of the main PC system.
this will be a good upgrade for my next chill box that I make.
two, how tight the build would be inside the chill box, for the next chill box I make, I will use a little bigger chest to make the box out of, or maybe I will really go all out, and make a solid aluminum box for the build, and insulate the out side of the box.
post #729 of 1657
And next time consider a thunderbolt breakout box, as i suggested some pages back - minimizing the amount of wires going from the chest is probably going to help get a tighter seal, and with the box enable you to have ample choices for connectivity

This build is impressive in scale and performance!

ok, so I have all of the plumbing done, and I am now ready to put it back together.
