3/8" Vs 1/2" which one is better?

I use 3/8" for the dual loops in my SIG RIG and will continue to use 3/8" until someone can show me a significant advantage to using larger (harder to route) hose.

Take the time to read his post and you will see only small differences in temps and flow with different sizes of tube.
For your loop, my personal choice would be 3/8" and a "Tee" line instead of a res, purely as a space saver. There is nothing wrong with using a res, as they do help shorten the time it takes to bleed your loop of air bubbles. A "Tee" line will do the same, just not as fast.

currently i have 1/2 and 3/8 barbs and will set up the loop tomorrow so no time for other barbs. how is the E6600 clocking on you? hope you can hit 4ghz+ club as you expected

If your going to use 1/2" tubing with 3/8" barbs, your asking for leaks IMO.
3.8Ghz 39 hour Prime stable is the best I could manage @ 1.488V Load. The temps hit 65C even with TONs of cooling power. I believe this chip has a somewhat poor IHS to CPU contact when it comes to high voltage. It boots into windows at 4050Mhz no problem, but temps hit 76C within seconds of starting prime.
For fun I am testing 3.3Ghz @ 1.248V Load so far prime stable. With this lower voltage & clockspeed load, I am only seeing 39C temps under load. That big of a swing is what is telling me I have poor IHS to CPU contact. I lapped the CPU to help in that area too! It's a nice chip overall though!

As RIG RIDER said, read Cathar's post. There are minimal differences in tubing size in temps/flow.
Personally, having used all three, the 7/16" is very nice. Fits GREAT over 1/2" barbs so not much clamping is needed. However 3/8 is very nice because of its size. It is up to you, but I recommend 7/16"

but 1/1 inch tube is still cooler... even if its just by a little bit.
and then what happens if you use more tube in your loop than carthur did maybe it will be cooler again?

I think he meant 1/2 and just missed his key and hit 1 instead.
As the graph shows, when it comes down to it we're splitting hairs. So long as you keep your tubing short you're not going to see a huge difference in performance with a good pump, especially since blocks have been getting less restrictive on average (as compared to the Storm, White Water, TDX, etc).
Use what you think will work/fit best. If you don't have a lot of room, 3/8 is just fine. If you have plenty of room, 7/16 or 1/2 will both work equally well.

911us .. i loved your avatar ... very funny ... btw i'm using a 7/16 tubing over a 1/2 barb ... harder to fit on the barb's but .. no leak for shure ...
