CoolIT Systems

Hey guys I just had a couple questions about the way I plan on setting up my loop with 2 gtx 480 FTW I intend on buying hear in the near future. any opinions are welcome and appreciated.

Currently in my system now:
-Coolit Boreas Tec chiller
-HK 3.0 cpu block
-koolance x-58 classfied nb and vreg blocks
- swiftech triple rad
-evga classified (59) original release
- tubing size is 1/4 id

Question #1

Now if I get 2 of these gtx 480 FTW will the water blocks on them allow me to use one of these www.sidewindercomp..s.com/bishg14si1id.html direct connect fittings between the cards? I have an x58 classified original release and was just wondering what the spacing would be and if the evga blocks would allow for a direct connection setup between cards. Then I don't require tubing between cards.

So it would go fitting on top side of #1 (top) card for entrance of water, direct connection inside between cards and another barb on the bottom side of the #2 (bottom) card for the exit of water. I dunno if i explained that for u guys to understand lol.

Question#2

The way my loop is now is Tec - pump - cpu - nb - vreg - triple rad - back to tec.

I plan to also get another double rad and use that to help exhaust the heat from the added 480's.

So the new configuration would go like this then Tec - pump - cpu - nb - vreg - triple rad- gpu1 - gpu2 - double rad - return to tec.

Does this seem like the best possible way to setup my loop after acquiring the 480s?

Question #3

I am using pretty damn small tubing (1/4 id) compared to what most people use as my Boreas requires a relatively slow flow in order for the tecs to adequately cool the liquid. Right now everything works fine and I am good with temps. Would all this extra stuff ( 2x gtx480s and double rad) be going past the pumps limits? I figure since the tubing is so small it shouldn't be a problem.

Its probably just gonna end up being trial and error but I thought maybe someone out there would have an idea.
Any thoughts or opinions are greatly appreciated guys. Cheers!

Trial and terror lol. That's a ton of heat to dissipate, and if/when the boreas gets overwhelmed, it all goes to hell in a hand basked pretty quick. Good luck and let us know how it turns out!

Hey thanks for the reply! Yeah im for sure not going to be able to put it all on one loop. My plan now is to leave the cpu/mobo blocks on my boreas with the swiftech triple as one loop. And im going to be making a 2nd loop with another swiftech triple but this one has the mcp 355 pump integrated into. The rad will be mounted to the back of the case with the koolance bracket and 6 fans in a push pull config on the rad. All dedicated to the sli 480's. Trial and error indeed... we shall see how it turns out!

Thanks

i'm curious as to how this turned out. i JUST purchased my boreas and i am still waiting for it to arrive, but i will be running a similar configuration with 2x gtx285's and an i7 965. my setup will have 3 double rads as opposed to 2 triples, but that should be about the same heat dissipation?? like i said, i would be VERY interested to see how this turned out -- and how your (OCed??) 480's work!!

Whoopyour,

Thanks for the post. By triple radiator and double radiator do you mean respectively 360mm and 240mm radiators? The GTX 480 gives off 250 watts of heat, so you would have to accommodate for about 500 watts of heat if you want to have two GTX 480 video cards in SLI. Saying this, 250 watts is what the card is published at, so it is usually a good idea to leave some head room when it comes to heat dissipation. Typically a 120mm radiator can dissipate over 200 watts of heat, depending on the water block surface area, air flow, and such. So a 240 radiator can typically dissipate about 400 watts of heat and so on. It may be a good idea to have a separate radiator based water cooling loop dedicated to your GPUs since then you could get a higher over clock with your Boreas unit (about 500 watts of heat dissipation) dedicated to your CPU only and since GPUs typically run hotter than CPUs a radiator based cooling solution should work very well for you in cooling your GPUs. Having said this we have our Omni ALC unit to be available around July. The unit will have an interposer plate that is compatible with a GTX 480. You would need two of them if you would like to run SLI since the unit will come pre-sealed and plumbed to a 120mm radiator.

A good water cooling loop could look like Boreas unit -> pump -> reservoir -> CPU -> Boreas unit. And for your GPUs - Radiator -> pump -> reservoir -> GPUs -> radiator.
I hope this was helpful.

Thanks TheJon. Here is a couple picks of my current setup! Sorry there small!







Modded my HAF 932 so the Boreas could fit inside. Its a little tight even with this massive case!

This is how My current setup goes guys:

boreas --> CPU block (HK 3.0) --> North bridge/ nf200 koolance block --> Vreg block --> swiftech mcr320 with push/pull fan config -->t-line and then finally back to my boreas. And im going to leave it like that.

Yeah by triple and double I mean 3x120 mm 2x120mm

And Ive decided to go with a 2nd loop dedicated for the 2 gtx 480 ftw hydro coppers. I just gotta wait for evga to get them in stock and ill probably be waiting a while. Could have pulled the trigger one one but I will only switch over for 2 as my two gtx 280's are comparable to one 480 in performance but they were limited to one per customer so i decided to wait... Ive got all the other parts ready and waiting here tho!

Ive just bought one of these to use as a rad/res/pump combo and it will be mounted to the fan mount on the outside of case :



Swiftech mcr 320 drive which is just a swiftech mcr 320 with a fill port at top and a swiftech mcp 355 pump on bottom with bitsbower 1/2 id compression fittings and the Koolance rad bracket.

And ill be adding 6 fans for a push/pull config also.

Dont know how its gonna look in the end but it should make for some decent gpu W/C'ing!

Thanks again guys ill try and let you know how it goes!
