Loop Question

[adman29]

Ok so I'm working on a new custom build, and I need some advice, and someone to tell me if everything sounds like it'll work:

The plan is:

 

Reservoir -> Radiator ->  pump -> Y Fitting -> GFX card block & CPU Block (Different lines) -> Y fitting -> Radiator -> Reservoir

 

Now I know that I'll need a pretty beefy pump, but I've been told that I'm going to have problems with the Y fittings. Is there anyone with experience on the Y fittings, because I'm pretty sure once I fill the entire loop, there won't be any problems.

Also: Compression or barb fittings? (Sorry, I'm a bit of a newb when it comes to watercooling...)

Go res directly to pump

2

Why use a y fitting?

Why not just go pump-gpu-cpu

3

Compression vs barb doesn't really matter, just use what ever looks best to you

-SNIP-

 

The order of the loop doesn't really matter since the fluid moves so fast through the loop, as long as you have the res above the pump so it never runs dry. As spwath mentions you can just go in series and have each thing after the other and not worry about using splitters.

Order don't matter at all. Just make sure the reservoir follow by the pump.

You don't want use Y fittings or parallel for GPU and CPU. Unless they have really similar resistance(universal GPU water block or such). Otherwise, the flow will move much slower at high resistance blocks (most likely the GPU block). Specially if you have more than one GPU blocks, the GPU loop will have really low to nothing water follow. Water like to go where have lest resistance pass, basically you by passed your GPU block/s.

That makes sense, Thanks!

Ok, so with that, do I need to go into a radiator between gpu and cpu? I'm kinda worried about thermals since this is a case with little airflow (I'm rebuilding in a powermac G3 case.

Nice, I own powermac g4

The order will not effect temps

Also, where will you get any air in that case?

I'm curious

Well the plan is I'm going to Dremel vents in the bottom of the case where there was just a wire management panel, and then I'm also going to Dremel a vent at the top for a second radiator (So no Blu ray drive ). The tricky part is the motherboard mounts to the case door... But I'm pretty sure if I give the tubing a little slack, It'll be able to open and close nicely

Yeah.

Powernac g4 is same.

If you leave to much slack, it will be hard to close.

That will be a cool build though, be sure to make a build log.

That's the plan, Thanks for your help dude!
