Plan for 2nd loop. Sound good?

[ctsoccer13]

So, the eye-candy that is the EK Classified full board block has me planning out a second loop for my system and I wanted to run some ideas by you guys to see what you all think.

Currently, I have a HK CPU block for my i7 920, a triple rad, single 140 rad, MCP655, and gtx285 in a loop (specifics in my sig). I have a 2nd gtx 285 that I'll be adding in because it had no compatible blocks for a while (damn EVGA) and the Classified block.

Because it's getting to be a pretty hefty amount of things to cool, I wanted to separate them into 2 loops. I know I'll probably end up getting another double or triple rad, still deciding which would fit. Thus, here come my questions:

1) Would I be better off putting the board block in a loop with my GPUs, thus isolating the heat the inferno that is the i7?

2) Is there a significant difference in running the GPU blocks in parallel vs. series?

3) Depending on 1 and 2, which pump would fit my needs best for pressure and flow? I was currently considering a 2nd 655.

4) If I was to use some bling connectors for both the SLI and 45-degree connectors, which would be best?

5) Anything else I'm forgetting?

I appreciate any/all feedback!

Thanks!

1) I'd probably put the board block on the GPU loop and test it out that way. If you have a triple for your SLI GPUs, you'll probably be okay with the block on there (Caveat, I don't know if the EK block is particularly restrictive).

2) I haven't seen definitive evidence either way, so I'd just set it up however you want. Not sure if it makes any difference if you have the board block in the loop, but I doubt it.

3) You should be fine with a second 655 pump.

4) The Bitspower 45 degree fittings are nice. Not sure what the best SLI fitting is for two cards - check out Koolance, Danger Den, Bitspower ... (some one will come along and give you an answer)

5) Do you have drain lines set up so it's easy to empty/change out your setup?


Have fun. You'll probably get several different suggestions. I think the best way to check things out is just to give it a go. You can always change it later.

I don't have any drain lines setup. I usually just detach from my res and let it flow into a bottle

If that works for you, than that's fine. I always seem to end up wearing the coolant when I try to do it that way

+1 to seperating the CPU into its own loop.

What are your temps on the i7 and GTX285? Are they overclocked?
What fans do you have, and what speed?

[ctsoccer13]

I'm currently just running stock clocks and settings. I know, I know... it's pretty weak, but I wanted to get my cooling system figured out before I crank it.

However, just simply with stock settings, I'm seeing about 40C idle CPU, 50 C GPU. On load, around 50C CPU, 60 GPU.

As for fans, I have 3x Scythe "Slip Stream" Medium speed fans (1600 RPM) running on a bigNG for the triple rad and a 140mm stock case fan that came with my HAF932 on the 140mm rad.

Not that I don't trust shazza, but no other opinions?

Maybe I should use Feser pre-mix with PT Nuke? I think I may put my res right after my pump in my loop. If not, I'll put my radiators in front of my blocks at least... it DEFINITELY reduces temperatures in a closed loop. Fittings are too restrictive. Computers are pointless as a whole.

Do NOT mix Fester premix with anything, it's supposed to have everything in it that you need.

Lol, you victim to my trap. Now comment on the questions above
