thicker then 1/2 inch tubing?

[Tokayla]

i wanna split a 1inch tube into two 1/2 inch tubes for cooling on differnt parts of the computer ie chipset + cpu & gpu + hd

is it worthwile using 1 inch tubing if i can find it or shall i just stick with a y conecter using 1/2 on both ends?

and ill be using a massive radiator

I'd say use 1/2" and split off with a Y to 1/4" or 3/8" for your 2 routes. I've never heard of anyone using 1" tubing before but I guess your reasoning behind wanting it is because you rad outlets are 1"?

Which radiator are you using? I'm interested to hear about massive radiators as i'm doing a new build myself which has unlimited space and am thinking about using a huuuge rad in order to get zero fan, passive cooling

My plan is to use a 1/2" feeder line, and branch into two 3/8" lines. I'm still going to use all 1/2" hose barbs thoughout, because they have a 3/8" inner diameter, they won't restrict flow from the 3/8" tubing.

Actually, the cross section of a 1" tube is much greater than the cross section of two 1/2" tubes.

(pi)(.5)^2 = .785
.785x2 = 1.57 <--Total cross section of two 1/2" tubes

To find a single tube that has that cross section:

1.57/(pi) = .5
(.5)^(1/2) = .7071


If you wanted to do this, 3/4 inch tubing should be all the bigger you need your larger tubing. Hence, 0.75>0.71.

My next water system is going to have two loops, One loop will be dedicated to the CPU, and will Use 3/4" tubing. The other loop will be for the chipset, GPU, and heatercores.

Good luck,

ill be using the biggest dammed car radiator i can find second hand so i expect it to be running of some funny sized cables , oh and probably multi in's and out lets..

Thanks for that info Iron Hawk - i've made a note of those formulas

 

[Rakk]

Oh & Tokayla, let use know what radiator you get & how well it works - which pump are you planning to use?

 

[Tokayla]

the heimen 1250 is that powerful enough for a car radiator?! i just read some radiators need 40-50 psi just for water to escape the radiator!

 

[Iron Hawk]

These water pumps dont put out verymuch pressure. Certainly not 40psi.

I recomend you use a few large heatercores.
