well here are the radiators, my problem is the configuration of them, simply too many possibilities, so if you could find the time to give your opinions, I would really appreciate it.
I also need advice on a type of shroud for the radiators, the purpose is to inshore good air flow through the radiator.
and lastly how to attach the fans to the radiators?



all advice is welcome and thank you

 
Solution
I don't use a flow meter, never have, never will.

Having a picture of a flow meter does nothing to support a finding, especially when you cannot be 100% conclusive that it is reading correctly or you are accurately converting what is being reported. Does the flow meter registering on the pump without restriction show a flow rate that is close to the rated flow of the pump with your conversion?

If so, great, but if so, you're still running lower than 1.0 gpm on your loop, meaning your delta-T MUST be offset to calculate your cooling potential. Meaning - you have to over-rad to accomplish the same cooling ability that you could achieve with a higher flow. Adding cost of 3x 360 radiators ($60, example) starts to get expensive...
Ok so I finished the video card loop only to find that after all of this long hard work and planning I still need 3 more fitting to finish the CPU loop so I ordered them and they should be here next week some time, but other than that it really is looking nice clean and tight. Even if a little extreme, I do truly believe that I have found a configuration that will work well, If not I can always change it.
 


I think porting your GPU returns into the pump intake is a bad idea simply because the lower GPU is below the intake level and all it will take is a big air bubble entering the pump intake and you could burn up the pump.

You should always have full reservoir water available to the intake of a D5 pump!

Now I'm fully aware those will come in and argue the position doesn't matter because somewhere in the massive loop the reservoir is before the pump in the cyclic life of the loop, but IMO it's a bad idea!

Now remember TM03, you asked for my opinion, additionally the GPUs could have been setup in series because the cooling difference between the primary and secondary GPU is only 1c in a series loop.

You could've actually saved some money on those fittings.

Otherwise it's your project man!

It doesn't matter what anyone else thinks, it's your money, it's your project, it's your build, do what you think is right!

You're probably better off not asking for other peoples opinions, because even if it's perfect some a$$wipe ( 😀 ) will find something wrong with it!
 
Wow you bring up a good point about the lower card being below the pump intake, even with priming the system well, I should probably place a flow meter on that side of the loop to monitor the possibility of reduced flow through that area, thank you for that insight.
 
that looks sweet man. just completed my custom res with a temp sensor and radiators but the two pumps together are so weak and it flows so slow. 2 sealed systems were only 25 shipped each and i had one already on my system ran good. upgrading the pump to a swifttech mcp 355

 
That is a pretty bad ___ system you have your self, I would like to see what kind of temps you’re getting with that setup if you do not mind. I am currently playing around with some TEC’s and plan to build a system with them for my next build so any input would be much appreciated, and thanks I have been working on it for a while now in an effort to get it just right, but there is always room for improvement. so I have to straddle my OCD and settle for what works.
 
[:lutfij:2] funny I can't seem to get notifications about these old threads I've been subbed to for so long...and the last postage was the last notification on tools progress.




@ Ryan - now that made me laugh hard!!!

@ tool - ze radiatthors need kaleening! vood you like me to dhust zem for yeeu!?! :) jokes aside, I like your progress and the stuff your rolling off your sleeves :sol:
 
Ok so I am looking for a way to add 2 to 5 inches of open space under the radiator case for tubing and wires I have already tried to use long legs but it is not stable enough for me so I am looking for something a little better than two red bricks with do seem to work quite well but look kind of well you know so any ideas would be helpful and thanks for your time
 
Now I'm fully aware those will come in and argue the position doesn't matter because somewhere in the massive loop the reservoir is before the pump in the cyclic life of the loop, but IMO it's a bad idea!

I'm in strong support of the reservoir -> pump inlet loop model...you always want to make sure a pump can only intake water and having a reservoir just prior to the inlet helps eliminate it from inhaling air while allowing excess air a place to converge to be displaced.

Also- I like the idea of parallel setup on the GPUs but I think you should consider running your radiators in only in serial. (Noticed the Y-connector on the middle and right rads)
 
Yea I did that to increase the water flow through the video card blocks, in serial I get 2000 to 2200 RPM through the cards but running them in parallel with the radiators I get 3000 to 3200 RPM through each card with in theory should help the cooling effect a little so i wanted to give it a try.
 
Well I am not for positive yet, but I do know the serial load temp that I am trying to beat, that is 59C after being fully loaded for four hours, and the system has reached its equilibrium temperature. I am not looking for much maybe one or two C drop off the top, so 55C would be best case and that is what I am shooting for but not expecting, and there is that possibility that I will get nothing for the trouble that I have put myself through to get to here, but it has been a lot of fun and it was worth learning. So either way I will still be happy, even if I do tear it down again to try something new if it does not work.
 




@TM03 The problem a Y brings to the table is the flow rate is compromised in the higher restrictive line and that may very well be the branch of the Y needing the most available flow rate.

So regarding the radiators in series, I 100% agree with Rubix.

Regarding parallel full coverage water blocked GPUs I stand by my earlier statement, the temperature difference between a parallel setup and series setup is not worth the additional work and investment to even do.

But it looks good, I'll give you that TM03 but the lower GPU as I have already said is below the pump intake, unless you've changed it since the last picture I saw.

Input here is to help you achieve the best possible cooling results, that's my goal, and my only goal!

Especially since you are an overclocker, you should be after the best overclocking routing of your setup you could possibly accomplish, doesn't matter if you're not overclocking.

But any feed line below the pumps intake of a D5 pump, that could have trapped air, is a tremendously bad idea that could cost you your pumps ceramic bearing.

In this case your entire bottom GPU block is below the pump intake!

I've warned you and that's all I can do, and that's the last I have to say about it!
 
I agree It’s a possible configuration issue, and I did buy another flow meter to monitor that exact possibility. If I see an issue with flow on that side of the loop I will change it, but as far as a faster or slower side to the loops configuration there should not be. The loop is the same on both sides after the splitter it goes radiator block and radiator block than recombined back to the pump reservoir splitter and to the radiators again.
 


Oh great! Another flow meter to increase the restriction!

As Bill Engvall would say, "Here's your sign!" :lol:
 
yea he is refering to the posibility of air constantaly getting traped in the lower card because of lower flow rates on that side of the loop with would cause a venturi effect, I will watch for that but I have run this configuration already and that was not a issue, still it is worth watching for so i bought a flow meter to look for it.
 


TM03, The one thing I respect about you is you will take a chance and take on a challenge that a lot wouldn't even consider, what I don't respect about you, is your bullheaded attitude to ask for someones opinion, just to disregard it, when it is given not to criticize you, but help you.

I think you only ask for others opinions in hopes they'll see nothing wrong to advise you to change, hoping for praise for a well done only, when a lot of us make mistakes we have to eat, and try to advise others not to do the same.

Seeing as how there are specific danger warnings with the D5 pump to never, ever, allow it to run dry, I just don't understand why you would design a loop that even the possibility of air getting into the pumps intake could happen.

I don't know?

Maybe they forgot to put the warning label in your D5 pump, and you don't know about it, and you think I don't know what I'm talking about?

I do understand after all the work you've done to get to this point it will be a pain in the a$$ to change it, but as many times as I have changed my setup over, and over, and over, I don't have sympathy for being too lazy to change something you've already admitted, (Quote) : "I agree It’s a possible configuration issue.", that could cause you a problem.

Trust me!

When you post your D5 pump has prematurely failed and just can't figure out why?, I will not be the sympathy promoter or be in agreement to others sympathy for you predicament, I will be the one laughing!

Well the only way to fix it would be to change the position of the pump below the second card with is a possible configuration for that loop, but that would also mean more fittings to add to that nice quarterly that bits power is going to have this year. No I will not allow my pump to fry I have been doing this for a while now I do know better. I have considered that exact change from when you mentioned it much earlier as well I have a redesign already done for that reason but I would like to not have to go there.
 
The warning on my rad/res combo is mentioned in a little pamphlet provided in the box the rad came in. Furthermore, shoggy at aquacomputer support said never to orient the pump to run vertical above water source, in their forums and talkbacks :) That bit of research lead me to the buy the vertical res for the way I had decided to orient the rad/pump.
