Can i split my 1 loop into 2 streams into 2 Radiators and back together.

post #1 of 21
Thread Starter 
Hi i want to build in a Ximatek Aquila at 1 point i want to split my loop into 2 streams 1 goes into a 200mm Phobya Radiator the other into a 280mm Alphacool Nexus after the 2 Radiators i want to go back in one stream into the pump.

Sorry for Bad English I am not a Native Speaker.

Not sure why you would do that, as that will not result in cooler temps.

You will need at least 2 Y connectors and I'm sure this will add all sorts of unnecessary bulk to the build inside the case for no real gains.

You are better off to make a single loop and stagger the radiators. A Y connector will not allow you to regulate how strong the flow is and could choke the weaker side and cause damage from improper cooling. Either make it a single loop or get a second pump and make it a dual.

I want to go for the cleanest look after the 2 radiators it goes back together and into the pump.
post #5 of 21
remember water will travel the path of least resistance, since you are using different radiators, you'll have to test it. I'm using both radiators same make and model so the impact for flow would be minimal apart from what was expected, flow / half, this was done using a couple of flow meters and Aquaero 5. You trying to make a cleaner loop which is why I did it also.


My old layout: T Block splits to drain valve and GPU.

Res > Pump > Rad 1 > Rad 2 > T Block > GPU

My new layout: pump goes into manifold, then manifold goes to Rad 1, Rad 2, side port is drain valve (lowest possible point in the case), then the 2x rads out to T block into GPU.

Res > Pump > Manifold > Rad 1 >
> Rad 2 >
> drain valve

Water temp results are delta of around 5-7c, ambient 25c, flow 1.03 gal/min (Im using dual D5 at max speed), 3x GTX Titans in loop (serial), GPU diode temps max I seen 40c, stock clocks, both 360 radiators are using GT15 push/pull, no difference before and after change.

Thx for the Help guys

You got a point on resistance.

I hope this helps to understand my situation.

post #7 of 21
I enjoy water cooling, and I have been doing it for about 20 years, my builds don't look all the good, but I build them for performance, not looks.(well, I did try to make one look nice, it kind of does)

house temps are right around 28C for most of the year,

this is a earlier build I did it has 2 radiators in parallel with each other, it has 2 X 240mm radiators, it has a CPU and GPU in series with each other, but the CPU and GPU water blocks are older blocks, with a open high flow design, so the flow rate on this system is 6LPM.
https://imageshack.com/i/04alldone003j
https://imageshack.com/i/joalldone006j

the load temps on this build are.
CPU 41C
GPU 51C
this system is a stock system with no clocks on the hardware

I did this build as a serial/parallel build it also has a flow rate of 6LPM, it has 1 X 360mm monstra radiator a CPU and GPU in parallel with each other, it looks nice, a lot went into making it look nice.
https://imageshack.com/i/0vfi2nJ
https://imageshack.com/i/exwiFW7Vj
https://imageshack.com/i/ezPiu5JIj

the load temps on this build are
CPU 48C
GPU 53C
https://imageshack.com/i/npuzs7j
not as good on temps as the older build, but also there is not as much radiator space on this build.
this system is also a stock system no clocks on the hardware

and the final build is my gaming rig, it has 2 X 360mm radiators in parallel with each other, and a CPU and 2 X GPU's in parallel with each other on a 3-way parallel configuration, this system is clocked, the CPU is at 4Ghz, the GPU's are at 580Mhz, and the memory is at 1600Mhz.






the load temps of the hardware are
CPU - 54C
GPU 1 - 45C
GPU 2 - 45C

the water temps at load are
33-34C
the delta t of the system at load is 4C
Link to Gallery
this system has a total flow rate of 9.6LPM
have a look at the total post
http://www.overclock.net/t/1573189/serial-vs-parallel-9-6lpm
if this system was stock with no clocks on any of the hardware, the load temps would be.
CPU - 35C
GPU1 - 37C
GPU2 - 37C
so I hope this helps with your rig, let me know please.

Thx for your reply Toolmaker i only want to run the radiators in parralel i now this sounds stupid but i want to go for a system with clear defined lines and without crazy bends.
Still I dont want to waste a fortune on fittings and dont want to go for plexi tube this pc is gone be moved around a lot so iam to afraid tht one of the acrylic tubes break or the fittings start leaking.
I want to use top AMD components like 290x and 8320 i already have and want to reuse from my last build. The Ammobox.
post #9 of 21
well I showed you 3 different builds so that you could get a feel for how a parallel setup works.
I hope it helps.
take a look at the first build again.

You could potentially get equal flow through both rads if instead of recombining to a Y, you have each one drain separately into the top of a reservoir that's not 100% full; basically, have a reservoir with two inputs at the top, one from each rad.
