Is one pump enough? 560+480 radiator | Aqualink restriction

[Gene5is]

Hello guys im going straight to the point:

 

1) Im upgrading my build, and im upgrading from a 360 Black Ice SR1 radiator to a 560 Alphacool Monsta + another 480 Alphacool Monsta and im wondering, is 1 pump going to be enough(im using a Koolance PMP 450S Strong High Flow Pump http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_201&products_id=25773)

 

Or should i just go dual loop?(HUGE HEADACHE to fill/bleed and replace components)

 

im cooling a 4770k, a Maximus VI Formula and 2 GTX 780 Ti Classified..

 

2) I'll also be using flexible Primochill Tubing(1/2 id 3/4 od) and i want to use 2 x Bitspower Adjustable Aqua Link Pipe II SLI Fittings(http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_393_766&products_id=34771 to cool both cards in parallel... and my question is, will they be greatly affecting my flow? or should i just use 1/2-3/4 tubing?

 

PS: Sorry for my bad english, i did my best to make myself understandable

it's fine yes.  I wouldn't recommend a dual loop unless you understand what needs to be done, and you plan on more than 2 graphics cards.

The performance increase from the SR-1's to the Monsta's isn't that much, the SR-1's are a good sweet spot in the >30mm low fpi range but since your obviously going for more rad surface area it's good. That pump should do the job but if your really concerned about it and just want faster liquid circulation you could go overkill and get yourself a bitspower dual pump top and throw two D5's under it. That's 3000L per hour vs 1020L per hour with the Koolance pump. The aqualinks should be good and are sexy af.

I was facing the same debate.  I don't have any experience with that pump but I do have the Swiftech MCP655 which is essentially a D5 pump.  It has more than enough power for my loop which is quite big and keeps the temps below 55 on the CPU and below 40 on my GTX 780 SLI setup which is setup in parallel.  Take a look at the setup - link is in the signature.

 

I'm running:

1 x D5 pump on setting 2

1 x 480

1 x 360 (30mm)

1 x 360 (60mm).

 

I too am using the Swiftech adjustable SLI fittings which are very small in diameter in comparison to the 1/2 ID tubing I'm using in the rest of the build.  I personally feel like they are a choke point in the loop.  My second gpu is always 3-5 celcius hotter than the other one.

nice build you got there!.. well ill give those bitspower sli fittings a shot and ill post results here...

 

 

any other suggestions or comments are well appreciated!.. thanks for the replies and help guys!
