Corsair 750D Custom Loop Build

So I've been stuffing all these hardwares inside a CM 690 II Advanced for a while, and the fan noise when that GTX 770 (Overclocked to ~1320MHz +12mV) is kicking hard kinda annoys me ( I get annoyed at 70% fan speed and above...Am I classified as silence freak? O.o ). 4670K is running @4.6GHz w/ Corsair H60 at fairly decent temp (~40 while gaming) & voltage (1.2V). 

 

I wanted to solve the 770 noise issue as well as to see how far I can push the CPU, so the idea of full custom loop came up. Given the size of this graphics card and limited room inside CM690, it is impossible to stuff enough radiators and a vertical tube res without modding (As much as I would like to, modding is not really an option for me at the moment).

 

But the URGE of building a custom loop is driving me crazy....so I spent a fair amount of time reading build logs to get some ideas, and as it might be a slightly overkill for this particular build, a Corsair 750D is now the choice of my new case.

 

I've placed the order of the case as well as all the supplies for water cooling. Here is the plan I have in my mind:

The graph contains lots of information and I don't think I need to explain too much. Reason there are only 3 90' fittings is that I live in Canada and dazmode is pretty much the only choice I have for ordering the supplies. At the moment they have only 3 Koolance 90' fittings in stock. I did not want to wait or spend nearly 20 bucks on a single Bitspower fitting. I know how awesome Bitspower fittings are but I really do not wanna spend that much on such a small piece unless I absolutely have to.

 

So I have a few questions here:

 

1. Are there proper mounting holes for pump/res up there? I bought a pair of 90 degree metal bars just in case I would need them.

 

2. Given all the water cooling parts, how would the temperatures of CPU/GPU be at very high load and overclocked (intense gaming and/or benchmarking)?

 

3. I've placed an order of Swiftech 8 way pwm splitter for all the rad fans and it is currently on back order. Any easy alternatives of controlling these many fans while I wait? I have no idea how much noise all those Cougar Turbines and AF140s are going to generate if I connect most of them to molex.....

 

4. Comments & Suggestions please!!

 

PS. This is going to be my very first water cooling build and I am so hyped right now~!! Dear Canada Post and UPS please deliver them quickly......

If I were you i would turn the rear exhaust around as it is closer to even air pressure (but still positive) which is better then really positive/negative. It will also look better as the colour ring will be on the front. Just a suggestion, besides that it looks super freaking awesome and can't wait for pics :)

Good point! I was worried that I would get even pressure with back being exhaust. I guess I forgot those are AF series :P
