That is a really nice dual housing you have there, are you running the pumps in parallel or series?

Also, just out of pure curiosity, do you ever feel that having two is just pure overkill or absolutely necessary? I only ask because I mean damn, 317 GPH is a strong friggen pump.

It's not that I am trying to shy away from having two pumps, it's that if I use two pumps now I have to reconfigure the loop depending on if I am running them series or parallel. Honestly for my setup I would probably run them as two separate pumps and give each pump its own loop; for example use one pump for the CPU and Motherboard blocks, the other pump for the GPU's only.

That is a really friggen nice dual housing, did you purchase that from FrozenCPU by chance?


they running one loop , and yes all the time cause as you stated that is allot of flow but at the same time they help each-other witch will make them last longer , and if one fails , I know one still runs!
so at the end of the day It does not bug me anymore lol and know I do not do business with frozen i only buy from Performancepcs they my buddy's biggrin.gif yea That would make sense to do that tongue.gif and haha thanks man biggrin.gif

Its simple enough to work out if your pump will give over 1 GPM of flow in a loop you plan. If you look at the PQ curve for a D5 Vario


You can see that for 1 GPM of flow rate the max pressure drop is about 4.7 PSI

If you take the pressure drop curves of each component you want to use, say;
An XSPC raystorm

2 X Titan blocks

2 X ST30 360 Rads


and add the pressure drop of each component at 1 GPM flow
Raystorm ... 0.84 psi
EK Titan blocks ... about 1 PSI each for 2 PSI total if in series
ST30 rads ... 0.49 psi each for 1 psi total
for a total of 3.84 psi pressure drop, with plenty of room for extra drop caused by fittings and right angle connections etc ... which means that the D5 will produce over 1 GPM of flow at full speed, or that for 1 GPM a pump setting somewhere between 4 and 5 will be required.
If the total pressure drop of all your components is over 4.7 psi then the flow rate will be under 1 GPM

That is simple enough to do.

To actually estimate the exact flow rate you will get is much harder of course because the pressure drop of each component rises and falls with the flow rate, and at the same time the pressure of the pump falls and rises in the opposite.

It also becomes harder when less popular blocks like motherboard blocks are used where there has not been any or little detailed testing done so it can become a bit of a guessing game.

Some people believe that RAM / Motherboard / Chipset blocks are very restrictive, but just like all blocks it is a very individual thing. Older chipset blocks have very narrow, tight water ways but if you open up a modern EK RAM or Motherboard block they are just flattened tubes inside without the micro channels of CPU and GPU blocks to restrict flow very much. As a result they are not all that restrictive or high pressure drop.

This too is extremely valuable. I have seen some of Martin and Stren's work and it truly is invaluable stuff; seeing these charts posted here in such a manner shows me how to essentially put all of that work into action in figuring out exactly what I am going to need. It also reminds me to subscribe to Martin and Stren so that I can have this stuff on hand and also keep up to date with their hard work.

This post is just as invaluable as the pump sticky that was linked to me, for that I thank you. I am going to see if I can find the restrictions, flow rates, etc of every particular piece of hardware I have put together for this build. It uses some mixing and matching between block brands, though they're obviously all constructed of the same materials. This just gives me more research to do and hopefully I will find out if I what I chose is on par or if there are better blocks or even radiators for me to investigate.

Just as a reference point I have chosen:

Koolance 380I for the CPU

Heatkiller GPU-X GTX Titan "Hole Edition" (Nickel/Black) GPU water block and back plate (x 2)

Heatkiller NSB Rev3.0 Chipset Water Block (Nickel/Black) (For southbridge)

EK ASRock Z77 Extreme11 Motherboard Liquid Cooling Block (I won't be going with ASRock for my motherboard, this is just for example / reference as I don't know whether I will be going ASUS or Gigabyte yet and hence I have not started looking for the specific model's cooling block...)

Alphacool NexXxoS Monsta Triple 140mm Radiator (Yes, the 80mm thick rad...)

Alphacool NexXxoS UT60 Full Copper Quad 120mm Radiator

Alphacool NexXxoS UT60 Full Copper Dual 140mm Radiator

PrimoChill PrimoFlex Advanced LRT Tubing 3/8"ID x 5/8" OD (Will be using Bloodshed Red as to avoid using dyes in my coolant, pre mixed or not)

So, it looks like I have some research to do. smile.gif The one thing eating me right now is the decision on the motherboard, but I will get around to it soon enough. I am currently using the CHV F-Z and before that was using the M5A99X EVO R2.0. I had success with both boards, however I also had some gripes with the CHV F-Z as well. Due to these gripes and the fact that I am switching back to Intel anyway, I am heavily leaning towards Gigabyte. I had older dual core Pentium rigs (P55 chipset if you recall those days smile.gif ) built on Gigabyte boards and they were absolutely solid and performed just the same.

Anyway I am going a bit off topic here, sorry, I have a tendency to tangent at times. Thank you once again for this post, now I can start researching the selfless hard work of others to see what I come up with an also possibly see if there is anything better suited for my build / liking.

Cheers!
