View Full Version : T line HELP please
Hi all. I'm in the process of setting my system up and I have a question about the T line. Here is a pic of what would work nice for me but I don't know if it will really work.

If this will not do does anyone have suggestions on a good spot for the T? I really do not want to use a res. Thanks.
i think a better place would be between your video card block and your pump. the t-line doesn't have to go all the way to the top. mine only 3 " long
The only problem is it's kinda tight from the gpu to the pump. I'm wondering if the T to elbow would be a problem. If not I would rather run it up there and I can shorten it alittle. Here's where I'm at.

i'd recommend before the pump as well. there's also the option of a small resevoir built onto the intake of the pump :)
I'm just curious as to why before the pump would be a better location for the T.
its just a more level place (no need for the elbow), and then it can help feed the pump intake.

with the T-line on the out off the pump, would it not push the water out if you don't sealed the end off the T-line when topping up, so you'd have to turn the pump off as you fill and on again ?
You know why don't they ever put a little bleed valve on the rads, then getting the air out would be easy like on a radiator in a house.
I've managed to fit the T inbetween the gpu and pump. I had to use a 3/8" copper T because my plastic T was too long to fit without going past the side panel. I f this looks good I'm going to remove the mother board and vid card and filler up for leak testing. Comments please.

i think it's worth while to make the T longer as you have lots of room in your case, cos it's a real pig to bleed the air out, you have to keep tipping the case, with a longer T you hold or bend the T-line to prevent the air from getting back into the loop.

I agree with Woody. I think its easier all around if your T is around 1 foot.

I like the copper T idea, but can't see hoseclamps holding the tubes onto it in the picture. Tell me that is just for fitting purposes. You really want to use hoseclamps of some kind when using the copper fittings. If you don't plan on hoseclamps, then take the copper fitting out and find another way to do the T-line using a plastic barbed T; it'll keep you from getting a case full of water at some point.
As others have mentioned, it will make life easier to make the T-line longer. On the part that just holds water, you can use a male-male barb to extend the existing piece of tubing. Flow resistance doesn't matter there. Unless you extend the T-line to higher than the radiator, you'll need a way to cap the T-line in an air-tight fashion otherwise the weight of the water in the rad will probably push water out of the T-line when the pump is off. That keeps it from evaporating also.

Another thing why didnt you place the rad at the front/bottom of your case? The tubing route would be much more clean and no problems for setting up a T-line.
I would add a shroud to that rad, that fan blowing through it is just loosing to much airflow.
As some1 already pointed out use hose-clamps :)

I think the rad is great where it is, it'd be more tubing to put it on the front of the case. Now you have intakes on the front and a big exaust at the top :)
I really dig the aluminum colored paint, maybe you could find some metallic water dye? Just a thought :)
Also, definintely use metal clamps! Extra cheap insurance. And if possible it would look better to paint/find a new t fitting :)

I disagree with crimedog on the amount of tubing used by putting the rad in front. I think you would use at least 6" less tubing. The problem I see with putting the rad in front though is you might kink trying to put your pump that close to your GPU the way you route now.
If it were mine, I would try the rad in front then go
rad > pump > CPU > GPU > rad
The disadvantage to a top mount is you are not using the best air to cool your setup. This just my guess though.
he could still suck from outside the case, just have plenty of exhaust on the back, and not a lot of intake on the front

I havent played with sucking from the top, but I have read a lot of threads about trying to defy convection. People usually have higher temps.

they look about the same to me tube length actually. but i think the top mounted looks a lot sexier.

Well drawing a picture does not help you, you have to actually move the rad to the bottom. Also right barb on the rad is intake and left barb is exit so you did the drawing the wrong way ;) Then
you should place the T-line between the waterblock and rad tubing this will allow a much more cleaner tubing setup :)
Thanks for all or the comments. I'll try to address most of them if I can remember. As far as hose clamps, I will be using them but I need to be right on before I finalize everything. That's why I've turned to the best H2O resource I could find, and I thank you. Adding another 8" to the T is not a problem, I bought 10' of clearflex60 it was only $12, so I have extra to try out other configs.
There is a shroud on the core but it's the one from Danger Den. It's acrylic and a bitch to drill. Mine cracked but still useable. I'm thinking of picking up another shroud.
The heater core up top. I tried to put it down below but there is a nother hard drive rack that is not in the pics that goes down there. It also makes things tight with the tubing to the pump. If the core was downstairs I could probably lose a few inches in tubing but with the hd rack back in place I have to mount it sideways and things run tight.
Right now nothing is in stone.
crimedog

uhhh... there's an intake on a heatercore???
where ever it goes, there's a fairly large distance between the components and HC. I think it's best where it is :)
I did some moving around. How does this look?

Does it matter which barb the pump feeds into the rad?
BigSmokey

If you could set you pump on its side that would eliminate some turns. That looks better thouhgh IMO.
Also, if your trying to get the best setup for getting water from the HC to the block, its more worth it to have the setup convient and fewer angles than straight from the HC. This has been debated but the outcome (based on my opinion of who I think the experts are) is that there is not a clear advantage to having the HC directly before the block.
In other words, if its convient for you to put the rad -> pump -> block, do that. Especially on the impingement blocks, the heat from the pump is minimal and you gain some pressure from the direct connect to the pump ("pressure" might be inaccurate but this is the gist of what was debated)
Cathar (imo, an expert) I think was the one who proved that the added heat was minimal and recomended convience instead of forcing an unnatural flow design.
With the rad down front I actually use more tubing than when it's up top. When it's up top the flow is pretty clean, no kinks. What are the differences between having the rad up vs down? I would be interested to know. I'm thinking that up top is much cleaner. Knowing the trade offs would help me get this up and running.
crimedog

pro's to having it up top: less tubing, looks neater IMO, can still use the front of the case as 2x80mm intakes (i assume that's what size those holes are) = better case airflow, top 120mm exaust.
con's to up top... i can't really think of any... maybe if you don't like how it looks?
oh yeah, the way the pump is feeding the rad is fine, the top one is out, side is in :)

If you use your case exhaust as your rad cooling air, your temps will be higher. I would estimate 2 or 3 degrees at least. The air from the case will be the warmest air in the room aside from right next to the heater duct.
If you use the top as in intake, you are defying the natural convection currents since heat rises.
If it were mine, I would reverse the flow and turn the pump around and reconfig the rig to run pump -> cpu -> gpu -> rad. That would eliminate some tubing and more importantly some turns.
I also like to mess with my system so I would test it every which way and find the optimum setup. I would also mod the case to take a 120 in front and put double shrouds on that core.
These are my opinions though. Its fun to play around and find what works for you.
I have a question on the lates setup. It looks like in the pic he is going pump/vga/cpu/rad. Is that what I am seeing? It looks like a WW cpu block and I thought the 2 outside barbs were intakes. Shouldn't you always go cpu/vga/etc.?

the centre is the inlet on the WW - the outer 2 are the outlets... so it's actually the exact reverse of your list, i.e. pump>rad>cpu>vga
I see, I had thought from what pictures I had seen that it was the other way, don't know why. I get mine the 28th - - Glad it's coming with instructions ;)

the convection of air currents is not going to matter in a 2 feet space, honestly. If everything else is set to exhaust it should be just as good as if it were at the bottom. Try both and tell us the difference :cool: .
Good luck, and it's nice to see you are thinking things out before bringing in the element of death.

Yes it actually does. Viewing your pictures you did the wrong thing. The right barb is for the pump and the left barb goes to the Waterblock.
If I put things back up top, which I kinda like it there, I will put a 120 intake down in front. As far as push pull, am I going to see a significant temp difference or will it be minimal? I really appreciate all the feedback everyone has given so far. Thanks. When it is all set I will post final pics and results.

regarding the push/pull fan option you will se little difference but it is worth the few extra bucks for 2 shrouds and 2 fans :)
I say keep the rad at the bottom front, add a T-line between the rad to waterblock tubing and you should get a cleaner looking setup.

Can anyone esle comfirm this, that the pump should go to the right barb on the rad.
If anyone is still following me I have a question about airflow. If the rad is at the bottom the fan will exhaust air from the case out through the rad to the outside of case. There would also be a 120 up top exhausting air out of the case.
If the rad is up top there will be a 120 fan exausting air through the rad out of the case. In front there will be a 120 bringing air into the case. In both configs there will also be 2 80's exhausting out the back of the case.
Is one of these better. It appears that the difference between the rad up top or down in front would depend on what other air flow I have going on in the case. I would appreciate any thoughts on this.

I think you will see the best results with the rad in front, but the only way to know for sure is to try it.

best would be rad at the bottom, with fan pulling air in through the rad, and a 120 up top blowing out.... that way you get the maximum temperature differential between water in the rad and the airflow over it (and hence maximum heat shed).

I love the silver color you painted the pump (and it looks like the rad is painted too...) looks alot better than the def. black and blue..
:clap:
Yeah, I had to paint the pump and rad. Just looks tight. I'm a fan of sh*t like that, some might call it anal.
The first run of this setup will be rad up top. 120 intake downstairs.
The way my case has been modded it's easy to change configs. But if things are running good it might take a bit longer for me to change everything. I'll let you know how the first run works out.
