Water Cooling Diagram

[markjonesx]

Which of these setups is the best/correct? anyone got any other diagrams;

Thnx in advance.

whats your CPU block.

And what is your pump?

 

[markjonesx]

D-Tek Fuzion CPU + Laing DDC-1T

Number one would be the best. Because the water is cooled then it hits the cpu block. The other one is the worst because even though the water is cooled by the rad you still have the pump which will dump a little bit of heat into the loop.

 

[trOver]

Res to pump to rad to block(s) is the usual setup am i right?

 

[tylerdustin2008]

Yes you are correct.

 

[aigomorla]

actually in his case it doesnt matter.

The d-tek has a maximum apex where giving it any additional flow wouldnt matter.

His DDC-1T will generate so little heat, i highly doubt his CPU temps would even nudge.

So Either way is fine, however diagram 1 would seem the most efficient. With your pump. Its not a super pump, however, its not a bad pump either.


IF you decide you want to change blocks to a ApogeeGTX, i would recomend you drop the pump after the radiator. The Apogee is more senstive then the D-tek when it comes in terms of flow.

Aigomoria

what block are you using on the quad?

the GTX still has me concerned..re:Aluminum issue but more so now the need to really bow the block and mobo(even with a backplate)

I got a PA120.3..working on getting a case for it..leaning toward the V2100B PLUSII

BTW sorry for the hijack

I would go with No.1...but the reality is this has been hashed over and over and most feel there is little difference...now aigomoria point on the GTX need more flow for max performance maybe be valid but I personally think there is little difference that will be seen with a single pump with a caveat..if your Radiator is very restrictive this may casue some performance loss vs a Thermochill PA series radiator(also the swiftech MCR rads are good) that is not restrictive

It has generally been accepted that order does not make a difference, so look for the one that allows you to make the fewest sharp angles (which impede flow) and use the least amount of tubing (more tubing = less pressure per inch).

On the contrary, putting a CPU block downstream from, say, your pump(s) and a GPU block will impart a fair amount of heat to it. There's also the Delta-T factor to take into account at the radiators intake. If efficeincy doesn't matter, then sure, slap a loop together any way you want. However, IMO, if you're going to spend good money on great components, why not try to get as much out of them as possible?

heh exactly. But in the op's case, he mentioned no instances of a GPU block. Only a radiator + cpu.

under normal ideal conditions, pump locaiton for this setup has very little impact. However, it has been seen and shown, to increase cpu block performance if its more dependant on head discharge of your pump.

IE. Storm, ApogeeGT/GTX, SP-05. D-tek with accelerator nozzles.

The op has none of what i mentioned, so therefore, having the pump b4 or after the rad has very little performance impact.

The D-tek is a extremely well designed block. It will kill the ApogeeGT/GTX in being less restrictive. This is why i recomend this block more to people who are running full cover GPU blocks, or gpu blocks in general.


But idealy, in a ideal watercooling loop, the radiator is always first, then the first component you wish to cool, CPU, if your crunching all day. GPU if your a hardcore gamer.

But in real applications you wont see much of a difference with the pump first or rad first unless you have one of the blocks i mentioned above.


@tyler. The GTX is nice. Expecially bowed. And so far i havent had any issues with it.

 

[HardWarrior]

All true, morla. My problem is that I find it difficult not to challenge sweeping generalities.
I also can't help but think that if you can plumb for the coolest discharge, why not do just that? The difference may be "only" 1-2c, but why not recover that much if possible?

 

[MotF Bane]

Aigomorla, aren't you supposed to have the first block in your loop be the one with the least restriction?

 

[jkresh]

If you check ocforums watercooling board they will agree with what I said http://www.ocforums.com/forumdisplay.php?f=71, mostly because each part only raises temp by a small amount and restriction is not important in terms of ordering. DOnt wory about restriction for ordering because water has to move at the same rate everywhere through the loop (think about it the loop is closed if water moved faster in one part then another then something would have to move in to take the empty space...)

he's correct again. Remember in a closed loop, flow is suposed to be uniform.

That means, the pump can only push out as much as it sucks. So it doesnt matter about which blocks are less restrictive or not being placed first.

The only given concesus and proven result, WHERE pump location was important was in the exception of the blocks i listed above. If you dont have one of this blocks dont worry about block location, unless you truely want that extra 1-2C as HW states.


Also my GTX is working pretty well: ambients in my room was near 75F when i took these.

core temps being off is the result of when i took this snapshot. I cant figure out how to load orthos on all 4 cores. The program used to test is BIONIC. its a World Community Grid application like F@H. If it can pass that, its raited stable for me.

I've always ran the cooling blocks right after the radiator, my thinking is the water is coolest coming out the radiator

that is true however, how long do you think the same water will stay in that chamber?

.1 sec? .2 sec? less then that even?

So how much heat in essense do you think 1cm^3 of water will collect in that short amount of time?

Not more then enough to cause a 1-2C temp difference if you had it the other way around. :]

"Water" is too broad a term. It's better to think in terms of molecules, they're the heat-transport unit of importance. One molecule of coolant spends, generally, as much time in a radiator as any other. But that time in the rad is potentially at lot more than a second or two due to buffeting and the motion inherent in a multi-pass radiator. If efficiency IS important, there's no reason not to plumb blocks at the rad exhaust. In fact there's no logical reason not to plumb this way, unless one has some sort of weird backplane architecture, of course.

As for me, considering how much I paid for this stuff, I'll gladly take that 1-2c.

That makes sense, i would think that the temp of the water before radiator and after exit wouldn't be that much different.
Good parts that work well together have a much greater impact on cooling then placement of your parts in the loop.
