Order of WC components...

Okay, so I have most of my components on the way for my system and I have a rather cramped case that I'm going to be fitting all of them into. The rad is up top on my 120mm blowhole, but the nozzles are on the end facing the PSU because my drives get in the way on the other end. Basically, I am looking at what could prove to be a rather difficult tubing job for all of this.

Is there any difference in performance based on the order of components? Originally I wanted to order it like this:
Pump -> Rad -> CPU -> Res -> Pump

But, this setup will be a lot easier to do with less drastic curves and such:
Rad -> Pump -> CPU -> Res -> Res

Any thoughts on if this will make a difference? I figure my flow rate will be a little better, but would the temp of the water going to the CPU be better if I had it coming direct from the rad? Is it worth a ton of extra work and such to get it to the first setup? Thanks for all the help, folks!
 
Unless your reservoir is going to be completely airtight then I don't think option 2 would work. If the res isn't sealed then you will lose your water pressure once the water hits the res and there won't be anything to push it though the radiator. I don't know what pump you are using, but I doubt it would be able to suck the water through the radiator.
 
I have it

pump -> rad -> cpu -> t-line (technically res) -> pump. the reasoning is a few things, 1) the heat from the pump will be added to the already warm water and disspated in the rad, so the coolest possible water will go the CPU, then the warm water from the CPU will go to the t-line/res where it gets somewhat of a chance to cool off (but not noticable really), then back to the pump and it cycles.
 
Was figuring that that was the best option (Rad -> CPU). Guess I'll have to do everything I possibly can to make it happen. This is gonna practically be a full circle to get it from my rad's barbs to those of the CPU block. Heh. ;)

Would Clearflex be a better tube in such a case as that?

You all need to brush up on your thermodynamics and your physics Kronchev...

In a watercooling loop, thermodynamics indicates that the water temperature in your loop will be the same no matter where it is in the loop. This is called equlibrium temperature, and there isn't a damn thing you can do to change it, not even placing the radiator in different places in your loop.

Trust a my degree in physics when I say it doesn't make a difference. The only thing that lowers your temperatures all things being equal is the flowrate. Putting your radiator after the pump seems to make a marginal difference in flow rates for the better, hence lowering temps a slightly (barely measurable).

As long as you go reservoir -> pump, the order of the other components doesn't matter.

jesus, I never claimed I was 100% right, that was just a theory :rolleyes: in truth thats how it all worked for layout so thats how I did it. Im sorry if I tried to make it seem like thats the end all of setups
 
i know putting pump inside reservior will increas temps.. but will the increased flowrate be for the better?
 
go to www.liquidninjas.com and check out some of the threads there.

Just plumb it in whatever order is easiest for you. having rad->cpu is prolly a good idea but beyond that dont worry about it...just try to keep the number of turns down and the amount of tubing used down too.
 
Sorry Kronc, I didn't mean for my reply to sound exactly like that... I guess you just have to read all my posts with an ironic and/or joking tone:D

Putting the pump submerged in the reservior puts mpre heat into the water than you would normally. 100% of the pump heat goes into the water, where as an inline setup only a fraction of the heat goes into the water, and the rest into the air. Only a larger radiator, not the flowrates, will remove the heat from the water.

As long as you go res->pump, its just the same as submerging your pump without the added heat (almost).
