Series Or 2 Loops?

[shadowman007]

WATER COOLING THE FOLLOWING COMPONENTS  IN A PHANTEKS PRIMO CASE: 

 

CPU:              i7 5960x

GPU'S:          2x SLi Titan X's

 

 

 

THE WATER COOLING SETUP:

 

Reservoir:    Koolance RP-452×2 (Rev2.0) which is a  dual D5 pump dual bay reservoir combo

 

Pumps:       2x EK-D5 Pumps

 

Radiators:  2x Alphacool 480mm radiators and 1x Alphacool 240mm radiator

 

 

Know my question is    with the above setup what would you recommend to go for? (a series setup one loop going all around the system plus both pumps working together in series)

or have 2 loops 1x 480 radiator just for the cpu and 1x 480 & 1x 240 radiator  for the 2 graphics cards? (2 loops will mean both pumps working separately)

for better temps id go for dual loops, that way tour cpu has its own rad space and your gpu`s have their own rad space and there not just all dumping heat into one loop, i could be wrong but it seems alot of people do dual loops with sli.

not to mention it looks way cooler imo

It only eliminates the heat rise of the liquid between parts. but if you are planing on pushing overclocks or having alot of heat generating parts then it is worth to do.

 

I would go with the 2 loops for the fun of it and you are going to dump a lot of heat into they loop. I would also run the 2 GPU's in parallel not in series.

Ya definetly parallel on the gpu's, so that both gpus can have cool coolant instead of the second/first card getting the cold coolant and the next gpu gets the warm/hot coolant that came out of the gpu before it

The difference between a single or dual loop wouldn't be a huge difference since the fluid moves so fast through the loop but if you can fit it within the budget and like the look of a dual loop then go ahead.

Thanks to everyone who has replayed so far really appreciate it. In regards to overclocking yes I will be overclocking the HELL   out of the cpu and gpu's.

Also another question in a dual loop setup would it be a good idea using the 240 radiator for the gpu which already has a 480? or better using it with the cpu which also has a 480? 240 kinda stuck in the middle between the 2

Between the two of them they have more than enough cooling but I would place it on the GPU side since they give off more heat in general with 2 in SLI.

Yea was thinking maybe I should just go with 2x 480's unless I will benefit from the 240?

If you have something like the 900D I guess you could go all out but it might impact things a few degrees at most during load if you wanted to keep all your fans at idle so not much in terms of cooling performance since the 480 rad is pretty substantial.

That was another thing keeping fans idle more radiator > run fans at lower speeds.

That for sure works well if your doing sub 1K RPM say abound 750RPM, just make sure your rads don't have a very high fin density to ensure easy airflow through them.

On the Alphacool 480's and 240 the Fins per inch is 10

You could do dual loops but depending on the rad room you have you could setup a smart single loop. For my build (the custom desk one) I have one loop but separated the GPU and CPU loop by a radiator. Instead of going from the CPU straight to the GPU (or the other way around) see if you can put a rad in the middle of that. That will reduce your temps before it gets to the other thing you are cooling. A speed variable pump would help in pushing the water around. Its worth a shot but it also depends if you have the room for it.

Yeah that's a fairly good fin density for low RPM usage.

Loop order doesn't make much of a difference since the fluid is moving around the loop so quickly, theoretically it would help but not in any meaningful way.

Thanks for that, the only thing I can do is from top 480 rad to cpu to 240 rad to gpu's to bottom 480 rad and back to res/pump combo.

Thinking of it know in serial setup if one pump dies the system will still carry on working same can't be said for a dual loop. Also if anyone can answer this if a pump dies in serial when replacing that dead pump would you have to drain all the system? or is it a case of taking out the dead pump and replacing it with a new one without  draining the system?

Yes if a series pump dies you would have to drain the entire loop as with any maintenance.

Unless you use quick disconnect fittings
