Thread Starter 
Relevant System Specs:
- Intel 4790K Delid
- Asus Maximus VII Formula
- EVGA GTX 980 TI Classified
- Fractal Design Define R4 Window
- Noctua NF-A14 iPPC-2000 PWM 1X
- CLU TIM

Goals for custom loop:
1. Cool CPU, mosfet and GPU
2. Silence
3. Take advantage of good silicon (i7 goes to 5.0Ghz@1.35V, Classy 1500/8000+@1.23V but temps and noise are high)
4. Keep costs low (~$300)
5. Make my maintenance life as easy as possible


Background:
Pretty straightforward. I am not chasing record numbers, I just want to lower my temps and noise. Any extra performance enabled is icing on the cake. Looks are not a primary concern at the moment. You can barely see anything in the R4 anyways. ATM I have a Corsair H100i (which I will sell ~$50) at the front of my R4 and the Noctua fan at the back (case fan at the bottom as well). IMO putting a rad at the top has too many drawbacks (no dust filter, more noise escapes, mobo clearance, etc). Assume the only options are the front 120 dual (140 dual is tight in the R4) and the rear 140 mount. I also have an EK 780 Classy block lined up for $60 second hand, so that is taken care of. (Stop me right now if this is not enough radiator real estate for my specs)

Question 1: Config
Given this requirement and my need to keep costs low I am figuring my best option is to go with a Swiftech H220-X at the front (takes care of CPU block, front rad/fans, pump and res) and then a 140mm rad at the back (reusing my Noctua fan). Does anyone have any more cost effective solutions?

Question 2: 140mm rad
Given my case, fan and the fact that I will want to take advantage of my mobo's mosfet cooling. I assume a slim 140mm rad is probably safest? Would a ticker rad be worth the tight fit? What 140mm rad is recommended?

Question 3: Fittings/tubing
Threads are obviously G1/4 (ID). Tubing (soft) should be 3/8ths (OD). For ease of use I rather go compression. Beyond that, I feel like I am missing something. For the H220-X I will need the adapter and 1 fittings right? That means a total of 7 fittings (1 H220-X, 2 GPU, 2 140mm rad, 2 mosfet)? Given everything above (cost and parts), any specific recommendations (tubing and fittings)?

Question 4: Other parts and accessories
Since this will be my first custom loop, I thought it would be a good idea to go with a non conductive coolant. Drawbacks? Anything else I should be aware of that I have not mentioned (or mentioned in error)?

Many thanks!
