Water Cooling Tube Sizing Help?

post #1 of 6
Thread Starter 
Im looking for some help deciding what Tubing sizing I should buy for my loop. Are there any rules of thumb that I should try to follow? Im using 2 D5 pumps in series, have 2 GPU cooling blocks, 1 CPU block, 8 RAM Blocks, 1 280mm Rad and 1 360mm Rad.

Tubing size makes next to no difference in performance...Choose what you think looks best. You could take a look at the WC gallery to get some ideas.

Is this because the bottle necking of a loop is in the blocks?
post #4 of 6
To a certain extent the blocks are the most restrictive, but with modern equipment and pumps, it's really not much of an issue. Just do what looks best. I don't like the look of the giant tubing but that's just me.

That's kind of what I'm thinking, going with some smaller 1/4" tubing. Any brand you would recommend?
post #6 of 6
A very useful thing to remember is the smaller the tubing and thicker the wall the better (smaller) bend radius in general.

So 3/8-5/8" will be able to make tighter bends then 1/2-3/4"


As for what brand is better, is a can of worms. I personally think all tubing will discolor and be subject to colour change when exposed to dyes, UV Light (natural light) and temp variations.


The plasticize problem seems to be a thing of the past now. Still occurs but on a far lesser scale.


IMO find something that is not cheap or mega expensive, and go with it.
