Herro.
I currently own a DigitalStorm pc. Dual 8800 Gtx cards, liquid cooled from factory. I am in the process however of creating my own pc...

My issue and the reason i cry for help is... I need to custom build a liquid cooling system for dual video cards... I do not want one of the cheap quick kits... I would appreciate some assistance in gathering parts to build this cooling system... I tried to look at my current pc and kinda just copy it but i dont get all the details from just looking...

I have only ordered a Processor and 2 video cards...
Intel Core 2 Extreme Qx9770 3.2Ghz
dual Evga 9800 Gx2 1GB video cards

Any info about a specific case you approve of, parts or guide to liquid cooling you have, or maybe even some info on those pre built liquid cooled cases... Could i just add a pump, tubing and some water blocks to the pre build and make a quality cooling solution?

Sorry if this is a troublesome thread just figured i would give Qcdn a shot. Searching forever online to only reach some child prick who actually knows nothing makes me angry.

Thanks guys.
 
feel free to send me the old pc stuff as it is still incredibly powerful and I have no idea why you're upgrading lol

Can't help ya with the liquid cooling stuff though, sorry><
 
Its not upgrading. I want to build my own and if it works great i will keep it and give the DStorm pc to my sister... If my build is not so great... She will get my build muahahahaha!
 
Liquid cooling is pretty much self-explanatory, but if you're doing several components (ie. chipsets, GPU cooling, etc.) you'll need a little bit of help as to how to cycle the coolant in a fashion where the most heat is taken away from the most important parts. If you're not looking to get too fancy you'll need:

* Radiator
* Water Pump
* Hoses
* Semi/Non-conducting fluid (wrong wording I know, but fluid that won't conduct electricity as much as water to keep from frying your parts in case a hose breaks.)
* Radiator Fan
* Mounting kits for each part to be cooled.

I had a quick guide around somewhere, but all I did to find it was google "pc water cooling how to" so it shouldn't be hard to find. The rest is up to how many fans, how big of a radiator, UV reactant fluid, yada yada bells and whistles. I say since you look like you're going all out on the upgrade here just hook it up to a car fan and radiator and funnel the hoses down to smaller sizes and mount that shit to a wall and/or desk.

Exactly why i have cried out for help. I would need to cool the chip sets and 2 9800 gx2s. The water blocks for the 9800gx2s seem to cover bother gpu's per card.

Kind of figured these were the needed parts, as i can look into my other pc and see these. I am kinda more interested in the details. Tubing size? Pump power? Amount of coolant in resovoir? Size of resovoir? Special fastenings for tubing? Radiator or fan size/power? I am guessing these all come into play? If there is just a standard for CPU and dual GPU i can not find it.

I googled a guide, i find basically what you just described to me. I mean is that really all i need to know? lol. Tried to youtube a guide and they all seem to use the little kits.

Gotcha, although I'm not sure what you mean by what I assume you meant as "both gpu's per card." Unless it's some strange special model that I'm missing, there should only be one GPU on the card itself.

Most hoses should have some kind of PSI reading on them, so if your pump pushes out 20psi you wouldn't want a 10psi hose. Again with that being said the pump you buy should tell you on the box or in the manual what the output is. I'm not sure the size of the fluid reservoir plays a key part, and unless you're using a milk jug, any reservoir you purchase should have a fill line. The fastenings (unless you buy used reservoirs or mounting brackets) will be on the pieces themselves, usually in the form of a pressure fitting. For the radiator is the bigger the better, diesel trucks come to mind, but you'd probably prefer smaller. The fan size should just simply match the size of the face of the radiator. The radiator will probably be marked on the package what size fan is needed. As far as the fan power, that's gonna be up to you on how noisy you're willing to tolerate. I suggest a Hi-Lo switch or something like that to vary with what you need during usage.

In the end unless you're a diehard tinkerer who really wants to make something custom, you're wasting your time knowing every little detail instead of just buying a kit IMO.

The 9800 Gx2 has 2 GPUs per card. The final setting will be Quad SLI.

Thanks. I am finding it comforting this seems easier then i was thinking it to be.

I would say i am almost a die hard tinkerer. I just do not have any experience building a water cooler myself. I was thinking the pressures and all had to be perfect to get coolant through water blocks at some perfect speed lol. Would you have a good kit you recommend? Maybe i can pick at it.

EDIT: I would go with another Digital Storm custom build but they are severly overcharging for quad sli liquid cooling. 9800Gx2 is only 2 video cards, 2 GPUs per card and takes one water block per card to cool... They are kinda charging as if it were 4 cards and 4 water blocks... The asshats...

Os, most likely they need to use two blocks per card though. That or a custom one for that exact model. Either way, it's a premium item. I've had trouble finding any good 9800 SINGLE gpu blocks, let alone double.

As for what size reservoir you're looking for, I don't think it really matters much, but enough to double the volume in your whole unit is the rule of thumb I go for. That is so there is enough there that the same liquid has more time to cool before going into the radiator again, thus achieving lower temps as a whole. The pump is a tough thing to map out, the bigger the better in most cases, just be sure that your fittings and tubes are going to handle the pressure before you crank it up to high.

Also, this can't be said enough. DO NOT test your rig inside of your case. Make sure you cut the tubes long enough for the final application, but do the actual testing with the water cooling cycle away from anything sensitive. Make sure there's a good couple hours of running without any leaks. It will be hard to control yourself but worth it in the end when it saves your $$ on a dead system.
