Experimental radiator \build log!!!

toolmaker_03 · Apr 14, 2012

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

I replaced the bottom of the reservoir with a bubble down, I added an aqua pipe to the top, and i attached the pump right to the bottom of the reservoir, all of this helped with getting to greater speeds.

ok so after going over the numbers it looks like I would need to go with a 5 way parallel setup on my blocks that would consist on one CPU block and 4 GPU blocks.
on the other side I will have 3 radiators to balance the parallel loop setup my objective is to reach 15LPM with 3 pumps the potential is there, but I do not know if I can get there or not.

and yea, I do have 4 video cards. :lol:

toolmaker_03 · Aug 18, 2015

here is how the loop potential flow rates might work out.
radiator 5.9LPM 5.9 + 5.9 + 5.9 = 17.7LPM total possible flow rate on a parallel configuration
radiator 5.9LPM
radiator 5.9LPM

CPU 4.6LPM 4.6 + 3.4 + 3.4 + 3.4 + 3.4 = 18.2LPM total possible flow rate on a parallel configuration
GPU 3.4LPM
GPU 3.4LPM
GPU 3.4LPM
GPU 3.4LPM

I will try to get 15LPM on this type of setup.

toolmaker_03 · Aug 18, 2015

ok so I now know what the restriction is on one inline filter it is it is 8.9LPM total flow through it.
as one pump will only flow in a loop at 8.28LPM you would not even see it on a single pump system.
so I will get another one so I split up the restriction.
inline filter 8.9LPM 8.9 + 8.9 = 17.8LPM total flow possible on a parallel configuration.
inline filter 8.9LPM

so I will put one on each radiator at the water out points.

toolmaker_03 · Aug 18, 2015

ok, I built the full parallel loop with two pumps and it is a little better the total flow after install 9.6LPM.

ambient is at 28.6

idle temps
CPU - 41C
GPU 1 - 33C
GPU 2 - 33C

water temps at idle
29-30C
load temps
CPU - 54C
GPU 1 - 45C
GPU 2 - 45C

water temps at load
33-34C

thank you, that looks a lot better, I will try and go back through the Serial vs Parallel thread, and fix it up like this.

toolmaker_03 · Aug 18, 2015

ok, so looks like it will be next month, before I can get the remaining mounting hardware, I would like two of them, for attaching the radiator off the back of the case.

ok so this is my theory on how I lowered my delta t on each configuration of my loop.
fist I need to have enough radiator space to remove most of the heat being generated.
than it is my opinion that the delta t of the loop can be directly related to the flow rate through the radiators.

here is how I came to that understanding.
on a serial loop with a lower flow rate through the radiators of 1.2LPM it has a delta t of 13C
on my serial loop the total flow rate through the radiators was 2.4LPM and I had a delta t of 10C
on my parallel setup with one pump the total flow rate was 6.8LPM so half that is 3.4LPM and that is the flow rate through the radiators on that loop and I had a delta t of 7C
on my parallel setup with two pumps the total flow rate was 9.6LPM so half that is 4.8LPM and that is the flow rate through the radiators on that loop and I had a delta t of 4C
well that is my theory anyway, it seems to work.

so for some practical application of this theory it seems that for every 1LPM increase in the flow rate through the radiators, the delta t of the loop goes down by 3C.
I would like to test this theory further by seeing if a flow rate of 5.8LPM through the radiators will continue to lower the delta t of the loop by 3C if so it would bring my total delta t of my loop down to 1C :lol: I don't think that is going to happen, but I would like to see what does happen.

toolmaker_03 · Aug 23, 2015

ok, so I think that i have figured out how I am going to get the 5 way parallel setup to run at 17.4LPM with the two D5 pumps I have now, I am going to get a pair of voltage step-ups for the D5 pumps.
http://www.performance-pcs.com/new-ppcs-12v-to-24v-dc-dc-power-converter-module.html
I would not do this if I where running a serial loop setup, as it is my opinion that the potential for leaks would be high, as the pressure in the system would also be high.
since I will be on a parallel loop setup, I do not think that the pressure in the system will be so high, that it would cause any leaks, but I don't know, i will find out though.

toolmaker_03 · Aug 24, 2015

ok, so the first time I tried to do a 5-way parallel setup with the CPU and 4 video cards, the results where not good, at that time I only knew how to get my loop running at 4.8LPM top speed, and that was with two video cards and a CPU, it did ok as a 3-way setup, but it was not great. when I connected two more video cards to the loop, the temps on all my hardware skyrocketed, so I took it apart and keep on learning how to get the loop to run faster, now two years later I can get that same 3-way setup on the hardware, of the CPU, and two video cards, to run at 10LPM, and I do think that even this, would be fast enough for the 5-way setup, of the CPU and 4 video cards. so I will keep on learning how to get my loop to run faster, until I can get to the speed I think is needed, before I try connecting the 5-way setup back into the system. I looking for 15LPM min and 17.4LPM max as my target zone for the total loop speed.

toolmaker_03 · Aug 24, 2015

so this is a sketch of the configuration for the 5-way parallel setup, I am thinking about testing first.

ok so I went back and did a really in depth look at all the systems that I have ever water cooled, and this is a break down of them, in order from oldest to newest.
the first H2OQPower system was to cool a super socket 7 CPU only at 550Mhz.
the second H2OQPower system was a to cool K7 CPU at 1.7Ghz to start and later a Ti4600 video card with block, I also added a 240mm radiator to the system.
then I up graded the first system to a K8 CPU at 2.6Ghz, a 6800GT video card, with two HHD's blocks, and I added memory blocks to the loop, I also added a 240mm radiator, then I upgraded the CPU block to a MPW50 CPU block, for this build.
then I up graded the second system to a intel CPU 4.3Ghz extreme core, and a ATi all in wonder video card with block, and I upgraded the CPU block to a MPW50 CPU block for this system.
then I built a third system to cool a AM2 CPU at 3Ghz, a 8800GT ultra video card with block, and I added the memory blocks to that system and it has 2 X 240mm radiators, I added a reservoir, a MPW50 CPU block, and a pump for the loop.
then I up graded the first system to a AM3 CPU at 4Ghz, and a 480GTX video card with block, I changed the 2 X 240mm radiators to a monstra 360mm radiator, the MPW50 CPU block for a Raystorm CPU block and added a reservoir and a pump to the system.
then I up graded the second system to a intel 2011 CPU at 3.2Ghz, and two 580GTX video cards with blocks, I changed the 2 X 240mm radiators out for two swiftech 360mm radiators, the MPW50 CPU block for a Raystorm CPU block and I added a reservoir and a pump to the system. I am still working on this system, I want to have 3 radiators and 4 video cards with blocks in total for this system.

so not using any fittings at all can seriously affect how well the system could preform.

http://imgur.com/wbPXaK1,EsTtsLQ,KA0KFFu#2

the lower the flow rate, the higher the delta t of the system.

rubix_1011 · Sep 6, 2015

Not sure I follow. Are you saying that using fewer fittings can improve flow rates? If so, yes, this is well known.

Well, yes, of course. This is common knowledge.

Lutfij · Sep 6, 2015

I was thinking the same thing. In fact I was wondering if the use of no fittings and the positioning of the GPU's and the tubing runs might've added restriction by inducing a kink... in the loop? For those areas you can easily avoid the issue by thoughtful tubing runs or some clever use of angled fittings though utilizing the ports effectively without angled fittings is the smarter of the two methods(or more)

*N.B:
Are we using a fan controller to monitor flow rate? Isn't that an inaccurate form of measurement? I don't know much about that department just wondered if that bit could be cleared up so to better understand this project

toolmaker_03 · Sep 6, 2015

not exactly, by adding soft 90 degree fittings to the loop, as I did in the test setups for the serial vs parallel comparison the flow rate was increased from 1.2LPM to 2.4LPM.

it seems that the transfer from metal to tubing causes loop restriction.

in fact, if I configured the loop as a CPU to RAD to GPU to RAD to GPU to res./pump and back to the CPU, the total flow rate of the system drops again, down to .5LPM-.8LPM.

Give a real answer? Not sure I follow this last post.

How do you give a real answer that fixes everything when you are simply troubleshooting a loop issue via written text on a forum? We aren't there to try different things to actually see what the flow rates are or to evaluate what is going on in a loop.

You make it sound so simple. 'Flow rate'.

Yes.

But the issue is troubleshooting what is causing the flow rate problem to begin with. It's like trying to help someone diagnose and fix a car transmission problem over text message.

1) you can't hear what is going on, you are reading the limited information being presented (which likely doesn't contain enough data)
2) there are multiple possibilities to 'why' the problem exists
3) the person you are communicating with doesn't have the knowledge to troubleshoot & fix themselves

Not sure why you posted several dozen links above?? No one is going to go through and read all of those.

toolmaker_03 · Sep 30, 2015

something I noticed last night while playing the last remnant I started playing around 4 o clock in the afternoon by that night 10PM the game itself was running faster than it was when I started so I asked myself why?
the only reason that I could come up with was that as the temperature in the house went down the system began to run faster by 10PM it was 68F in my house and the CPU was only getting to 39C the GPU's where at 30C at load lol it was almost too fast to play at some points. (no, I did not have turbo mode active)
