How many compression fittings will I need for this loop?

[nednerb]

Hello,
I am new to water cooling and would love some advice.

Setup
Case: Silverstone FT02B
Motherboard: Asus Ramage IV Extreme
GPU: 2x 7970 Asus Matrix Platinum

Watercool Parts
Koolance RP-452X2 Reservoir
Koolance PMP-450S 12/24V Water Pump x2
Magicool Triple 180 Slim Radiator
EK Supremacy CPU Waterblock Full Copper
EK-FC7970 Matrix - Acetal+Nickel x2
PrimoChill PrimoFlex Advanced LRT Tubing Red 1/2ID 3/4OD

Loop
Res>Pump>Rad>CPU>GPU1>GPU2>Res

I'm using this setup as my guide when building the loop.

Despite this setup having 2 RAD's the creator has indicated that he will be removing the 2nd RAD and taking the loop straight from the CPU to GPU and replacing the 2nd RAD with a fan.

I like the look of this setup and probably wont be deviating from it.

============================

I just need someone to help me verify how many compression fittings I need. Bear in mind I am running 1 Rad, and 2 GPU's as opposed to 2 Rads and 3 GPU's in the video and picture.

The picture shows 2 Quick disconnects and a filter/flow meter in between. Pretty sure I wont be including that in my build.

Compression Fittings
-----------------------
1. Res Out
2. Directional Change
3. Rad In
4. Rad Out
5. CPU In
6. CPU Out
7. GPU1 In
8. GPU1 Out
9. GPU2 In
10. GPU2 Out
11. Res In

Last question is in relation to the SLI/CrossFire Fitting.
Is this all I need to pass water from the first GPU to the second GPU?

Sorry for the long post and much appreciated for your help.

You should need 10 compression fittings. The angled fittings doesn't need additional fittings.

You might want to check out how the 7970 blocks work. Your picture shows the fittings being mounting on both sides of the card. However the 7970 can only have the fittings mounted on one side. What the 7970 block does come with is a EK-FC Link. It positions the fittings to face outwards and that can connect to an EK-FC Bridge.

Also im not sure about that choice of radiator. 180mm seems pretty intense but slim is the opposite of that. You need cooling performance equal to one a 3x120mm triple thick radiator.

Thanks mate that clears up a lot.

I have been playing with this type of setup for some time now, and I have a setup much like the one you have suggested here. There are some things that need to be considered here, one being the amount of radiators needed to cool this large of a setup, the other is the amount of restriction a serial loop of this size will have on the total system flow.
here I have a build log, have a look if you like, and ask questions if there are any.
