Is 1/2'' too big?

post #1 of 18
Thread Starter 
My loop is going to be as follows

Res-aquastream xt pump-aquastream xt pump-360-cpu-120-gpu-120-mobo-ramp-360-return to res

Now is 1/2'' hose overkill for this? I was thinking about just going to all 3/8'' hose?

There is really no difference between 3/8 and 1/2.

I have some 1/2'' by 5/8'' tygon hose but seems to kink really easy any recommandations on some different hose?

im using 1/2 x 3/4" but that's because I wanted to keep a (minutely) higher level of fluid in my case

actually on some watercooling reviews I have read over the months, there are temp difference between the smaller and bigger size tubing (I remember I once read someone said that he experienced 2-3C difference), bigger the tubing the better flow rate you would have. thing about people using smaller tubing is space. you got a small case that doesn't have much space to route tubing then better off with smaller tubing.

There was an extensive test and post on this subject a couple years back, and basically ... It doesn't matter.

Here is a link to the full review of 5 different tubing diameters and fitting sizes:

http://www.overclockers.com/forums/showthread.php?t=515368

In a nutshell, here is the summation:
Quote:
The final CPU temperatures work out to be:

6.35mm quick fit = 34.21C
8mm barbed = 34.08C
8mm quick fit = 33.91C
9.6mm barbed = 33.89C
9.6mm quick fit = 33.80C
11.1mm barbed = 33.79C
12.7mm barbed = 33.77C

So there we have it. The differences between varying tubing sizes.

Okay, the more astute of you will point out that the block C/W is really the case-to-block C/W, and that the actual CPU-die-to-block C/W is a lot higher. Even if we triple block the C/W (which would be an absolute upper limit based upon older research), we get:

6.35mm quick fit = 50.11C
8mm barbed = 49.74C
8mm quick fit = 49.31
9.6mm barbed = 49.25C
9.6mm quick fit = 49.04C
11.1mm barbed = 49.01C
12.7mm barbed = 49.00C

I'll leave it to everyone's own personal value based judgement to determine the relative importance of the differences seen....

It's certainly not the 5C figure that people bandy about. I never expected that it ever would be myself. In my own testing with arbitrarily choking the flow-rate in a test-system, I've always been amazed at the low flow resilience of many setups. Below 2LPM is where things start getting pear shaped quickly for most systems. My recommendation is that even if you're a low-flow fanatic, always ensure that your flow-rates are above 2LPM at the very least, and preferably above 3LPM if at all possible. Still, even when given 1/4" tubing installed with quick-fits and a decent pump like a DDC2, we can see that flow-rates in excess of 4LPM aren't a problem.

thing with smaller tubing is that with all things constant (completely identical loops) with two different size tubes using the same blocks, pumps, rads, etc....the smaller tubing actually should have a greater pressure due to more force being exerted in a smaller space. there's a lot that goes into determining temperature variance: ambient temperature, flow rate, radiator space, fans running, fan RPM, radiator FPI, pressure in system, internal temperature of the case, volume of water, etc. In all honesty, 2-3* C is really a drop in the bucket when you're dropping your temps 25*C on water. Anything variable like that can be altered by adding more rad space, looking at your fans, etc.

Thanks For all the replies! I will stick with the 1/2'' and will look at some stiffer tubing......

I ran 3/8'' and 1/2'' tubing on my loop, i noticed a 1-2c difference, which can be attributed to ambient temps.

Just get 1/2''
