Do you know how nice it is to bleed it outside the case?

Just a question about your loop... the tube coming out before the pump is called a T-Line, right?
And do you put it before the pump? Someone said that it needs to be the highest point in the system.
Nice loop btw

Yes, it is a T-line. The best spot for it is right before the inlet of the pump. This way, you are always adding coolant into the pump first when bleeding. This ensures that the pump never runs dry (very bad, can burn it out)

The T-line does not have to be in the highest spot once the loop is bled. Most people will turn their case on its side and lift the T-line out. This then makes it the highest point, but that is only to get the bubbles a place to go. Once the loop is bled, as long as there is some coolant in the T-line itself, it will be fine.

It is like the finger and the straw trick. If you put a straw in a glass of water and plug the end with your finger, then lift it out of the glass, the water stays in the straw. This is becasue there is no place for air to enter to displace the area that the water was in. Now, if you had the loop set-up like mine and them punctures a tube or removed a tube from a fitting, you would have a mess. Once there is a place for air to enter the loop and displace the vacancy left by the water, things start flowing.

Tis is a poor description. I have a very good understanding of how this works and such, just hard for me to explain, lol.

That's a t line and you should put it before your pump for filling purposes.
very nice. must be super convenient..

yeah, its so nice, when you put it in the case you have to leak test all over again. when you move that stuff around you could un-tighten your barbs, amongst other things.

No...how nice is it?

I've never understood building your loop outside your case tbh. I mean, I tried it once, and it was a failure. I'm a much larger fan of attaching everything, filling the loop, and turning the thing on! I just have my wife help me look for leaks during filling =)

Same here. I couldn't be bothered to put a loop with 4 water blocks together outside my case, so I just slapped it together and hoped for the best. My leak testing consisted of the time (about 5 minutes) that it took to bleed while on a separate PSU. The difficulty in fitting 7/16 tubing over 1/2 barbs gives one a lot of confidence. Add some teflon and orings to each barb and you have a very reliable system.

TBH, I didn't plan it this way. When I first set up this loop I wanted to keep it all internal. It just so happens that I can pull the whole thing out in one unit. I have never had a leak from moving it, either. Just because I can take it out as one unit doesn't mean I all of a sudden became careless and fling it around, lol.

Wow, tough crowd this morning

that would look sweet in my case, i just wish i had the extra to go back to water cooling... i miss the low temps and good oc's.

Looks nice and compact dralb.
I do wish that I could pull my loop out in one piece. I want to lap my processor because am getting pretty bad temps, but I have to drain it and pull really tight radius tubing off, so I'm delaying. Damn concave IHSs.

Just remove your CPU block, then remove you CPU... why would you need to drain your loop?
Unless you meant lap your waterblock?

My lines are set up in such a way that removing the processor will be difficult, but reinstalling it nearly impossible (I think).

dralb, what are your temps, and what vcore are you running for 3.8GHz?

I can take my system out as well, and I don't have any problems with leaks; imo, it can handle a bit of movement.

My temps for 4.2GHz @ 1.31v are ~60c on hottest core for small ffts, and ~58 for Prime 95 blend.
