Flow question

post #1 of 9
Thread Starter 
Ok, so I recently added two gtx 460's in place of the old 6870, and when I tubed it back up, I went pump/res<rad<cpu<gpu1<gpu2<pump/res with most of the cycle running downhill. The problem with this is there is A LOT of tubing. My question is, with the d5 im using, can I run the water UP the video cards instead of coming down? IN other words, could I go pump/res<rad<gpu2(bottom card)<gpu1(top card)<cpu,pump/res? I mean the way it is now goes all kind of up and down anyway, and if I could do it like this, I could cut out about 2 full feet of tubing. What do you guys think?

Pretty sure you can do whatever you want, just make sure its all going forward

Why don't you just do this: res > pump > rad(rad is on the top so it all goes down) > cpu > GPU1 > GPU2 > res

I would cut out all the excess tubing. No need for it and you're making the water travel a longer distance. Realize also that your blocks are your restrictions. You naturally want water to be flowing down, not up. Forces of gravity

your first scenario looks a lot better,you may save a foot of tubing the way you want to do it but your cpu will suffer-eventually you reach equilibrium,but there is still maby 2~3C to play with (you want coldest liquid to hit the cpu first)
The best way is res>pump>rad>cpu>gpu/s>back to res
any pics Jonesey ?

No pics right now, It's late, and I'm ripping everything apart day after tomorrow to install new board, and blue tubing. And my radiator is not on the top, it's mounted to the back externally, and the tubing comes in from the bottom of the case. I will put some pics up this weekend after I decide how I want to do it and get it done.

You are aware that it's a loop right?
Gravity is completely irrelevant.

Yeah flow can go either way, it won't make a difference at all.

LOL. Just because it's in tubing means it can defy the laws of gravity? Right....

Refer to the 2 diagrams below: (if I understand OP correctly)
Red loop (existing)
Pros:
1.water from radiator enters CPU first, making it beneficial of the coldest water
2.water goes 'downhill' from CPU to GPU1 to GPU2
Cons:
1.uses 2' more tubing, making the case more clustered

Blue loop (proposed)
Pros:
1.uses 2' fewer tubing, making case more 'clean'
2.water from radiator enters GPUs first, making them beneficial of the coldest water
Cons:
1.water goes 'uphill' from GPU2 to GPU1 to CPU


IMHO, the 'uphill vs downhill' is not too important here (~1.5 feet of water head?).
So, the issue seems to be ''Which gets the coldest water vs Case looks cleaner'' issue.
As I personally prefer the CPU receives the coldest water first, I would take the red loop (ie form follows function).

No difference at all between the water going "uphill" or "downhill". The only distance the pump has to push the water is the height of the reservoir.
