starting an ambitious build, comments welcome

Postby AxelCons » Mon Sep 23, 2013 8:56 pm

Hi, I want to build a multi-motherboard computer and i have done a lot of research on the construction of it, this is going to be my second build and my first water cooled build and i'm a little nervous because of it. (it's just two PC's in the same case; a server and a "client")

this is my setup.

1x Red Harbinger Cross desk/case

Gaming Mobo:
1x Gigabyte G1 Sniper 5 Gaming MoBo
1x Intel i7-4770K Series CPU @ 4.2 GHz
4x nVIDIA GTX TITAN W/ 4-way SLI setup
4x Avexir Venom Series 8GB DDR3 2133MHz Dual channel
1x Lapatek G1600 (1.6Kw) PSU


Server Mobo:
1x Super Micro H8QG7-LN4F Server MoBo
4x AMD Opteron 6300 Series CPU @ 3.7 GHz
32xKingston Technology 16GB (1x16 GB) 1333MHZ DDR3
1x Lapatek G1600 (1.6Kw) PSU


Koolance parts:
4x CPU-380A water block (AMD)
1x CPU-280I water block (Intel)
2x 4x120mm 30-FPI copper radiator
2x 3x120mm 30-FPI copper radiator
2x CHC-125 Water Block (Super Micro)
4x VID-NXTTN water block (GTX TITAN)
36x RAM-33 waterblock (RAM)
Clear UV-Reactive 13mm x 19mm (1/2in x 3/4in) PVC tubing

The reason for all the unnecessary parts is i want this thing to be able to run under quite a lot of stress and have the ability to upgrade to more powerful equipment in the future without having to buy more powerful everything as well. as well as the ability to brag ;)

the way I want the cooling to work is by tying in 4+ pumps/res in parallel and the rest in series but i have a feeling that the length of the pipe plus 51 or so parts will constrict the flow and reduce the effectiveness of the setup and that 14 cooling fans wont be enough, I feel I need some experience in this field of work and any advice or comments are welcome.

4 parallel pumps running into a series loop doesn't work very well, you can find very lengthy explanations on it. If one pump fails it acts as an open in the loop causing the water to feed backwards through the broken pump instead of through the loop at full speed/pressure. So it doesn't give you any redundancy and performance gains are minimal. You can fix that issue with a check valve but they don't seem to be common for computers.

Other than that it looks like it will be a fun build and extremely overkill. Nothing stands out as troublesome except for the powersupply in the server. The CPU TDP's are around 120W iirc + everything else won't even probably break 600W-700W, but that isn't the issue. The problem is with your electrical source. To run 1.6KW PSU's under full load please make sure the wiring in your house and the breakers etc are up to that kind of load. Might need to separate circuits, one dedicate to the gaming board and the server can be hooked up with everything else.

EDIT: a 15A breaker is not designed to run at 15A it is designed for a PEAK load of 15A and really should only be run at a constant 12A load.

thank you for the advice, im pleased to see that someone with more advanced knowlege then me sees so few problems besides the PSU and the pump, is their any pump config that you would recomend for this build?

In all honesty though I have had one pump fail since 2003-2004 when I built my first liquid cooled computer, usually it was something else that failed first. Personally with your parts list I'd probably still end up using 4 PMP-450 pumps but it would be 2 series loops, with 2 pumps in series for each loop for redundancy. The PMP-400's are also very good pumps but they seem to work best by themselves and I personally find the PMP-450 a bit quieter overall.

I do see other problems like 4 titans are really more of a show piece than something practical but it will be a really nice show piece :). And I cannot say much when I have two 6990s in a machine, and a radiator that is probably meant for a small car.

Another thing with a budget like that 2 Quality UPS's might not be a bad idea. I bought the biggest one I could get my hands on for a 15A circuit and its 1200VA or something like that but it is only capable of 900W so I had to unplug everything but the tower and one monitor from the battery side otherwise it was too easy to overload it. I have had to keep the 6990s to the factory BIOS position to keep from having the alarms constantly go off when I boot something demanding up.

wow, i thought UPS's were discontinued for PC's. only seen them at a Computer recycling center and they were 9-15 years old. That will be great to have.

thanks for all the help you have given me, i was kind of expecting to get no response or a slap in the face but this has been excellent, I do appreciate it :)

yeah the 4 titans are definatly overkill but thats what they were made for, no? :D

I did some looking up on the UPS and i found an Eaton 5130 W/ 1250-3000 VA, it isn't the most powerful thing but 2 should keep my system running for at least a few hours.

I saw the desk that you were getting and now hopefully I will be able to pick one up soon lol. You will have a great experience on how to setup your loop especially with all the room you have for it. I'm jealous lol.

yeah it is a beast, the people designing them did a hell of a job and im talking to them about getting 2 "9 fan radiator" trays in mine.

If I had the money I would snag that up in a heartbeat but right now my danger den case is doing just fine. Anyone want this case hehe. When you start building it post some pictures of the process and the final product.

will do, im getting the money for this, the budget is almost $25,000 so it will take a bit of time lol

Sometimes with these budgeted things if you don't use the budget properly it won't happen again in the future, or the budget won't be as big. So another thing to consider...

Pick up 2 x HXP-193 and 1 x EXC-800.
Put a HXP-193 in each loop then use the EXC-800 to run to both HXP-193 units (parallel might work best).
If you do it right leaving the radiators in place in the loops still what you can get to happen is have the radiators do the primary heat removal then the EXC-800 doesn't have to work as hard to bring the liquid temperatures down even further. And by using the HXP-193 exchangers you only need 1 EXC-800 and the loop will still remain separate, and you can always choose to turn it off.
