Water cooling stuff

I thought it was supposed to be pump -> rad -> cpu -> gpu -> res -> pump. I read somewhere that the case temperature may raise the cooled water in the res if you do rad -> res -> pump...

🙂 My pump doesn't add any heat to the coolant, so it doesn't matter. Really, what was the reasoning behind that? It doesn't quite make sense that rad -> res would somehow increase temps.

I'd imagine that having the rad dump into the res would give you a pool of cooler fluid to draw on, offsetting any extra heat a pump MIGHT add.

Hmm, I think the reasoning behind the setup I explained was that it is assumed the temp of the water right after coming out of the rad is cooler than the air temp inside the case. If that's true then if you have it go from rad to res before going to cpu, theoretically the water temp will increase. By how much I don't know.

Akira, are you doing a custom res? If so may I ask what the materials/design is going to be? If not, can you show me which one you would buy? Btw, I am inspired by your setup and now I really want to mount the res outside for many good reasons.

My reasoning exactly, Dr. Akira34. 🙂

But isn't the biggest offset of any additional heat the rad? So wouldn't it be best to have it go through rad right before going to cpu? Anyways I think this isn't a big issue in the end. Sounds like a choice of personal preference that doesn't change performance much either way.

Maybe, but the rad works better if the water is as warm as possible when it gets there. Being that I don't use a T-line, and taking this factor into account, it seemed more reasonable to feed the pump from the res -> my two blocks. Assuming that the res coolant is ALMOST as cool as that which just left the rad, this makes sense. I've got about a 16 inches of tubing between the rad oulet and the res intake, BTW. Also, because of where I had to mount my res, I saved maybe a foot and a half of tubing with this configuration.

 

[akira34]

Any decent pump won't add any heat, or not enough to measure, to the fluid.

I'm not making the res myself. I'm just mounting it outside the case and then making a sheild/shroud for it.

On the contrary, we're just starting to see pumps for water-cooling that don't add much heat to the water. Most, if not all, pumps actually use the coolant to cool themselves as well.

 

[gotensan01]

Can you maybe post a link of where you're buying it?

 

[akira34]

HW, do the pumps add enough heat to measure or to effect the system cooling at all?

I'm getting my res from frozencpu... I'm 99.99% certain that I'll be getting the Innovatek Tank-O-Matic Rev 1.1 res...

Monster-class pumps (Iwaki, the larger Eheim's) add enough to measure, sure. As far as true effect, that would depend on your circuit, lots of factors.

I like those, I just couldn't figure out a place to put it. They're annodized, correct?

 

[akira34]

Dunno if it's annodized or not, I'll be finding out when I call the order in. Of course, I'll be using the fluid (or addative) that makes it irrelavant.

 

[gotensan01]

Annodized meaning what exactly? Is it a process to get rid of the problem with mixing copper and aluminum parts in a water cooling setup?

 

[gotensan01]

Hey, I found this res that would fit really well in my setup. The only problem is that I have no clue how to implement it. First off, does it look like there is an easy way to fill it? Secondly, what are the two "brass endcaps" on the oppositte side of the 1/2" brass fittings?

Nice! It looks like you fill it from the plugs opposite the barbs. Anodizing=A process used to coat metal for protection purposes. Yup, protects metal from the "battery effect."

Ugh, sorry I'm so stupid HW...but I still don't see how it will work. Is this something that is common in res's. I don't see what kind of connection you use to fill it. Also, won't it be two open holes that water will leak out of after your system is complete? How do you close them up?

 

[gotensan01]

Oh, I see how it works now. This website gives a good rundown. Basically I will have two barbs for the water in and water out connections. Then I'll have one endcap just to close off the whole thingy. Finally I will prolly have another barb to connect it to a short piece for a "crude" fill and bleed system. Hmm, does this seem like a good system? First of all I'm thinking it would be better if I could find some sort of valve like swiftech uses in their fill and bleed system. Then I wouldn't have to try to pull the little endcap off of the little piece of tube sticking out. I guess I just need people with experience to tell me how easy to use this res seems.

As soon as I have the time I'm going to add check valves just before my pumps return to make the loop a snap the flush. Nah, you don't need that. Just grab a pencil and paper and sketch out your circuit. Think it through and if doesn't make sense resketch until it does. Oh, as near as I can tell, there's nothing wrong with hybridizing, as long as you keep it tight.

 

[gotensan01]

What exactly is hybridizing?

Using aspects of different methodologies. Like having a res and a T-line in one circuit.

 

[gotensan01]

Just thought I'd give an update. I have been searching the FS/T forums and so far I have gathered this:

Swiftech MCW5000-64. It has a 3/8" to 1/2" conversion on the barbs. I know this causes a choke but I like this block
Danger Den Z chipset block
Danger Den gpu block with 45 deg barbs (old style block)
Dtek pro-core rad (modified with my hammer)
Hydor L30 pump
Clear cylindrical reservoir
10' of Clear Flex tubing

Stuff I will buy:
shrouds and accessories.

Once I get everything, I'll try to do some benchmarks before wc it. I'll also try to upload pics of my progress for install.

EDIT: added more items to the update list.
