This is the first time i am watercooling or overclocking. I have a few questions :-
1. I personally like the way hardline looks but do i need angle fittings or can i bend everywhere?
2. MSI X99 Gaming 7 motherboard. Do I need a 40 mm or a 60 mm SLI bridge to connect my two cards and keep them running at least at 16x/8x ?
3. Should i overclock each card and then run them in SLI or run them in SLI and just OC the whole setup.
4. Can i comfortably OC my i7 5930k and 980ti's with an EVGA 1000w P2 PSU?
5.This may sound stupid. How does radiator math work? If i totally have 1320mm of radiator in my system and plan on cooling 3 components does that mean i have 1320/3 = 440m of radiator for each component? Can I comfortably OC the above CPU an Graphics Cards with that much radiator?

Thanks in advance.

1. I use a combination of bends and angle fittings depending on where I need to go. You can bend in any direction you need, but you still need so much length of tubing before turning in a new direction. This and the fact if you mess up one angle in the length of tubing, you'll need a new tube and start over.
2. Your motherboard manual should indicate which slots to use when using SLI for your 5930k. I had to use 2 specific slots for my 5820k SLI. Once you know this, you can look for correct size bridge based on Nvidia's website for spacing sizes. http://www.geforce.com/hardware/technology/sli/bridges For your 5930k, you would get the full x16/x16.
3. I'd get SLI setup, then OC them together.
4. Plenty of power, shouldn't be a...

3. Never had an SLI setup before, but it would likely be better to overclock the whole setup.
4. Yes, that's more than enough wattage.
5. You need one fan "space" per 100W TDP of stuff to cool. You have at least 640W of stuff (assuming a reference 250W per 980 Ti and 140W CPU). That would be seven fan spaces, so something like one 480 (four spaces) and one 360 (three spaces) would be the minimum. Depending on the specific graphics cards, their TDP might be higher -- I've seen as high as 300W for a 980 Ti. If you actually have 1320mm, you are overkill on the radiators -- like 360 over, assuming a worst-case 300W per 980 Ti plus the 140W CPU. So yeah, you have more than enough for maximum overclocking.

4. Plenty of power, shouldn't be a problem there.
5. 1320mm of Radiator is plenty for your planned setup. I'm cooling my 5820k, 2 970s, and VRMs using 960mm of radiator space. I don't have temp issues w/ my setup. Granted, you'll cooling more w/ OC 980Ti SLI and I'm not sure how much my VRMs are adding to my loop, but I'd think you shouldn't have a problem.
