From what I've seen there is little real benefit to running dual loops. You end up with a vipers nest of hose often with conflicting colors of coolant for slightly better temps.

You can certainly do it but you would need double everything: two pumps, two reservoirs.... If that is the road you go down, you will need to plan your loops VERY carefully to make it look nice.

alpenwasser - thanks again

I will do:

pump--->radiator360--->cpu--->gpu--->radiator240--->reservoir--->pump

After this small upgrade hoses layout should be better

That should work.

UPDATE

What about separate loop for CPU only and GPU too? Is this would work better?
Why I'm asking? Because we all know 4770k gets hot no matter what on high OC but is my GPU keeping my CPU behind because of 35C on max stress? My max core was 51 on CPU how much I can subtract from it if we removing my GPU from the loop? What temps I can expect of CPU on single loop?


Thanks

^This. Dual loops are expensive and rarely provide benefit proportional to their cost.
I really wouldn't recommend that. Having all the cooling capacity (i.e. radiators) in one
loop is much more optimal, it allows it to be used where it is needed when it is needed.

If you have a huge case and unlimited budget you can do some cool stuff with multi-
loop setups, but even then cost/benefit is usually abysmal.

Finally the dual loop and just build it tidy message is starting to get through

*sits back with a brew knowing the kids are learning!

lol. Thanks for teaching us papa!

What temps I can expect from dual loop? Im more interested in lowering CPU temps not GPU temps.
I know price to performance ratio on dual loop is bad but I need to know I will cut at least 5C down on CPU or not.

 

[Surfie]

No one can really answer that for you mate.

It would really depend on what radiator you assign to each loop, and any number of other factors.

Don't forget the main reason to water cool in the first place is to get high performance at a very low noise level. Having maximum radiator space in a single loop will yield best overall results as unless you are planning on using this machine as some sort of rendering farm, your gpus will very rarely be taxed at the same time as your cpu, meaning that whatever is working hardest will be cooled best by ALL rad space you have. Splitting the loop in that case would actually lower over all performance.

However if you are planning on working both very hard at the same time, be prepared for the tradeoff: noise will be higher because you will need your fans to run faster to dissipate the heat that each rad is trying to get rid of.

Back to your question; is it feasible to get a 5 degree plus drop by running dual loops? It is possible, however I'm not sure that it is worth it for the reasons I put above.

<...agreeing with this...>

^This.

Whether or not you get better temps with dual loops you can only answer after actually
trying it out.

You might even get worse temps as long as you're not fully stressing both CPU
and GPU, since, as Surfie has stated, you have the full heat dissipation capacity
available for whatever produces heat if you go with a single loop, and as long as
it's mostly one component producing that heat it will have more radiator surface
available for itself than in a dual loop setup.

If you had enough components to try it out I'd say go for it and report results (I'm
usually all for experiments as long as it's just wasted time in case of failure) to
be sure, but seeing as you'd need to buy an additional pump and res I would
advise against it.

It would also make things very cramped in that case.

That's another reason not to do it imo. I have seen many attempts at dual loops in my research time in planning my first loop.

I think I have seen one which didn't look too bad. (It was a client build by Singularity Computers: Cytotoxic I think it was? I also remember him saying specifically that he was splitting the loop for aesthetic reasons. No performance gain in it at all ) in any event for a first loop (and really any loop in general) I'd say save your money, time and heartache: do a single loop.

Guys is this means that adding 2nd radiator to my single loop is pointless too? I need to think about 2nd loop but from what I read from you guys it looks is waste of money + time so I might quit doing dual loop.

 

[tinytomlogan]

Actually thats the best way mate. Thats what we are trying to say. Just make it tidy.

My orca rig is

res -pump-rad-rad-cpu-gpu-gpu-res

Its the tidiest way to do it in my rig and thats the whole point

Adding a second loop is wasted money, adding a second radiator to your
first loop on the other hand is a great idea IMO.

What I'm trying to say is that having a separate loops, one with a 360 and one with
a 240, is a worse idea than having one loop with both the 360 and the 240 in it
(at least IMHO).

What ever you do res - pump is what comes first, the rest doesnt matter just make it tidy and use as little hose as possible. I used 40cm in total in orca

Single loop playa. If you were constructing this for a show to win a prize, by all means dual, hell triple! IMO you can't have too many rads - to a point, of course. I'm certain my loop is overkill. 3 480s for 4 blocks? [insert sinister laughter] My rule of thumb is, if possible, to construct a single loop where the fluid spends more time cooling off than it does heating up. You can get blindingly anal and do the math. I just threw a whole lot of rad at it. :lol:

A lot of people do. That said, more radiator surface area, the lower the fan speed you need. End result: awesome temps for almost 0 noise.

Having said that I just run by the rule of thumb: number of blocks +120 as a minimum. In my own project, I currently have 2 blocks (will increase to 3 later) and 600 mm radiator space. This means I exceed the rule of thumb, which then means that I can expect to run lower fans for the same temp gain.

Edit: of course there is a point where no further gains are possible.

Hey Champ,

abit of constructive here for next time you play with it.

Where ever you can try to cut down on the criss crossing and shorten up so of those hose lengths. obviously you're going to sort out the pump mount

you spend an extra half hour- hour on those little finishing things and you'll see the difference. with this sort of stuff anyone can buy the parts and slap it together. but its that bit of extra time and care that will set your rig apart from the next guys.

Just something to think about.
