I am working on my second WC build. I am going to be making the last of the orders tomorrow. And I wanted to find out about Compression fittings, are the better then normal barbs? Do they effect the loop + or -? what would you suggest if I was to go with them? This build is as much about looks as its about performance. But Performance is top dog in the rank of things. And what about quick disconnects?

Also was thinking about putting in 1 t at the backside of the pump with a close off value for a drain line, would that effect performance? And would it work? I know to put it at the lowest point. but should it be avoided for performance or if I do it, should it be before or after pumps?

It's all about user preference tbh. Barbs are cheaper and easier to install. Compression fittings look better (in my opinion) but cost more. I've had tubing come off of both types of fittings over the years, so I don't really think there's a huge performance difference. (Reeeeeeeeeeallly tight bends)

Oh, compression fittings make your thumbs hurt when installing a bunch of them at once, but at least you don't have to cut the tubing off when you want to change your loop!

Ok question I was thinking about putting in some 45degrees on the blocks and such, would that be useful or is about looks to?

I'm using four 45º fittings to keep my bends somewhat straight personally. I do recommend picking up a few just to be sure you have everything you need when putting your loop together. It really helps to draw out what you plan on doing with your loop, and going from there.

Extenders aren't a bad idea either. I picked up a few when putting my system together, and they came in handy on a tight bend from my 120 to my gpu block. Something like this: http://www.frozencpu.com/products/12...=c101s1354b145

And if I get the 45 i linked or like it, what brands are good compression and how do I know what to get? and I am using right now 7/16 hose in a 1/2 barb. would I still go the same way with a 1/4 thread? or would I do with 1/2 with all compressions made that way just get the hose inner and outer to pick the compression?

I prefer bitspower, but enzotech makes some nifty stuff too. Almost all watercooling gear comes standard as a G1/4" fitting, so you don't have to worry too much about having incompatible gear. (I would double check on the specs though just in case. I bought a bp 655 top, and it was 3/8" fittings, so I had to make an emergency run to home depot to grab some 3/8 to 1/4 reducers! )

There was a thread a little while ago where someone wanted to use 7/16" tubing on 1/2" compression fittings. They stated that they have a friend that uses it, and hasn't had any issues. I personally (as do others) recommend that you stick with the diameters in which the compression fittings are manufactured for. They are very specific and will state something like 1/2" ID 3/8" OD. You want those numbers to match the diameter of the tubing you're going to be using for optimal fit.

you don't have to cut tubing if you are using barbs. you can just slide them out with bit of wiggle lul.

That depends Mekaw, quite a lot of barb users install a smaller tubing than the barb so it's close to impossible for it to come off. You just heat the tube up, slip it over, and it clamps on real tight as it cools. But then you have to cut it off, or soak it in real hot water for a while before it comes off.
I have compressions where possible, because they're easy to work with, but I also have barbs in places I can't fit compressions... they both work just fine, no real difference for the flow rates.

It is all about preference, personally I sleep better at night with compression fittings. The only drawback is they are a little rough on the hands when installing and changing tubing down the line.

true.

but i doubt 90% of users use 7/16 on 1/2 barbs. though people seem to make big fuss about 1/2 barb on 1/2 ID tubing leaking etc etc. I have yet to experience any leak with my combination of 1/2 barb with 1/2 ID tube, with hose clamp there won't be any leaks from the tube.
