Looking for some tips on the optimal loop to cool my upcoming Sandy Bridge!

(this will be my first water cooled build)

Loop will include:

* 2600K (overclocked)
* GTX 580 SLI (overclocked)
* Chipsets + MOSFET

Chassis is a Corsair 800D. I haven't decided 2 or 3 radiators. I'm not modding the 800D, so a 240 at the bottom is out of the question.

If I go with two radiators:
- 360 @ top
- 120 @ rear

For three:
- 360 @ top
- 120 @ rear
- 360 externally @ rear or top (whichever is less obtrusive and more efficient)

I'm thinking push-only radiators internally w/2000-2500 RPM 38mm fans (I don't think there's room inside for push/pull). Externally I could go wild; push/pull 38mm + shrouds? I haven't decided on any brands or models for any water cooling parts. (open to suggestions)

I'll be using two pumps in serial, for optimal flow but more importantly redundancy (back up).



Now my shopped up loops. First two radiators:













Now three radiators! Also I could go w/external 480 instead of 360. What do you think, overkill?









Which style # do you think is optimal and sufficient for my cause? If none, suggest me a loop (that doesn't involve modding). ;-)

i'd keep it internal w/ a 480 up top, 240 on the bottom, theres a video on youtube that shows you how to mod the bottom.. 480 will fit with light modding

why do you have 2 pumps next to each-other in every one?

correct me if i'm wrong but i don't think that would do anything

Whoops, the outlet arrow is going the wrong direction on three radiators style #2. I'll fix it in a sec.. (should be pointing to the pumps)

No modding! I don't really want to saw up this case, especially if I decide to sell it later. I lack a dremel or jigsaw too.

Aren't two pumps in serial not that uncommon? e.g. Hulk v2. I could stagger them.. but that's just extra tubing.

you won't need 2 pumps for that loop...

What about redundancy? But seriously, I've seen many single-loop two-pump configurations on this forum and they're no more complex than the 3 radiator loops I've suggested.

it's not about complexity, you just don't need it.

You're killing me here with your vague 1 line responses!

At what point does a single loop need two pumps? I thought redundancy (i.e. back up) was a popular idea.

You're saying the following is excessive? (note bottom radiator)

post #10 of 26
that, isn't to excessive because (mostly) of that ram block. those are known to be extremely restrictive. that pump(655), isn't known for having a lot of head. a single 355 can handle your setup.
