Water cooling newcomer

[ChompingCho]

Hello there, I'm starting my first custom water cooling loop once I get the corsair obsidian 900d from NCIX and I was wondering if anyone could take a quick look at what I will be using and give me a heads up if anything does not work/better options are available.

I'm not quite sure how many fittings I need, but I know I will be using the following:

Swiftech 1/2IN x 3/4IN Lok-seal Compression fitting: http://www.ncix.com/products/?sku=72220&vpn=3%2D4X1%2D2%2DG1%2D4%2DCF%2DBK&manufacture=Swiftech&promoid=1294

Swiftech 3/8IN x 5/8IN G1/4 Lok-seal Compression fitting: http://www.ncix.com/products/?sku=72219&vpn=5%2D8x3%2D8%2DG1%2D4%2DCF%2DBK&manufacture=Others&promoid=1294

Swiftech G1/4 Male-Male Lok-Seal SLI connector fitting 20mm to 33mm: http://www.ncix.com/products/?sku=72224&vpn=G1%2F4%2DMMEXT%2DMEDIUM%2DBK&manufacture=Swiftech&promoid=1294

I intended on having it run from reservoir > pump > CPU block > Rad 1 (240mm attached to back exhaust) > GPU Sli > Rad 2 (attached to the bottom of the case > reservoir

I will most likely be using Noctua NF-F12's in push formation on the rads.

Well you may need another radiator, are you worried about noise? Have you looked at the Black Ice SR-1 radiators? They're good if you want lower RPM fans but they aren't super high performance.

It also doesn't matter how you run the loop for performance. Like cpu ---> 2nd rad - - - > GPU to get cooler temps won't really work. If you watch the Ultimate water cooling guide he explains how the hottest part of your loop compared to the coolest is only about +/-.1 degree Celsius.
