Need Watercooling Help

[gilbadon]

Here is the setup I was thinking of getting. Not all the parts are hashed out but if you see a major issue with what I am getting let me know. My major question is with the pump and res. Is the pump strong enough to control what I need and will the res work with the MCP350 with a top inlet? Also let me know if I am missing something.

Case: Fractal Design S

Fittings: Will be painted

Tubing: Will be painted
3/8" Copper Pipe from local hardware store

Pump:
MCP350

Reservoir:

CPU Block:
EK-SUPREMACY MX

GPU BLOCK:
EK GTX 980 TI/Titan X

Fans: Not chosen (Need 3 120mm and 2 140mm around 1200-1500 RPM)

Any suggestions are appreciated. Keep in mind, despite doing this expensive hobby, my goal is to keep as cheap as possible which is why I have chosen some odd hardware such as the fittings.

Hardware: (Planned not purchased)
z97 Mobo
i7 4790k
GTX 980 TI

That copper is going to be fairly tedious to work with but doable.
I'm not a fan of blowing hot air inside the PC case.
I would probably go for a 420mm in the top.

With a 140mm in the back moving the original back fan to the front of the case.
For the pump I would get nothing less than dual D5's. The reason for this is if one pump happens to give up the ghost you can still use your PC till you get a replacement.
The 140mm fans will run quitter and you would have plenty of radiator space for what your building. (the RMP your looking for means a lot less than the CFM)
These would do and be very low noise.

You could get higher CFM fans if you wish.

Thanks for the the feedback Zerk!

That copper is going to be fairly tedious to work with but doable.

Is that because the width of the copper, or is copper tough in general? I have found it is cheaper and easier to bend than acrylic. A copper bender can be had for as little as $10 where as I cannot find a good acrylic kit for less than $40.

I would probably go for a 420mm in the top.

I see your point. Just wanted to utilize the case front and top for a better look. That will probably save me money too.

For the pump I would get nothing less than dual D5's. The reason for this is if one pump happens to give up the ghost you can still use your PC till you get a replacement.

This seems a bit overly protective. At $70-$100 a pop that really hurts the wallet. I am fine if my PC does not work for a few days while I get a new pump in. Anyway, I would still be interested in how this works or if you have a cheap idea for dual D5's (Using tube res). Personally, a big reason I did not chose a D5 to begin with is because the mounting seems to confuse me a bit where as the DDC seems very strait forward. Also it seems more expensive. I am just nervous about the head pressure of the DDC pump with my systems restrictions.

You don't need dual pumps in this loop, but you will want something other than the MCP350; at least the MCP355 or MCP35x or better. You can also stick with a D5, but it is natively 1/2" ID unless you find one with G 1/4 threads to mount fittings.

I'm not familiar with those fittings, but I hope you are comfortable with using them. Are they G 1/4 thread size?

980 Ti and 4790k - are either/both going to be overclocked? What is your total, estimated loop TDP x .85? (85%)

Thank you for your help rubix,

Okay thank you. I think I will go with a single D5 (with G1/4). The one that looks like the best for my purposes and is cheap is the Koolance PMP-420 at ppcs, I cannot find much info on it though but it seems to have good head pressure and flow rate at maximum. I just do not know what its curve looks like. It might also be noisy which would be a major bummer.

I'm not familiar with those fittings, but I hope you are comfortable with using them. Are they G 1/4 thread size?

I am comfortable using them. They are shark bite fittings which are amazing and yes they are 1/4" bspp fittings. A big reason I am getting them is because they are BSPP(European Metric thread) to Imperial which is rare but makes getting copper a lot cheaper as I can just get it locally.

980 Ti and 4790k - are either/both going to be overclocked? What is your total, estimated loop TDP x .85? (85%)

Both will be overclocked as much as I can get safely. My conservative guess is:
GPU: 300W
CPU: 120W
300W+120W = 420W
420W*.85 = 357W


FYI I am also changing my reservoir to a DIY project.
Something like this:

I have a g1/4 tap so I will be able to connect fittings to it.

I've made a few DIY reservoirs in my time.

I ran a D5 Vario on setting 5 for about 5-6 years and was super quiet.

Sounds nice. I emailed Koolance about the PMP-420 to see some more information on it. If it does not have good performance, I will probably just get a standard D5 that runs on 5 permanently. I have been having troubles finding one with g1/4 threads instead of that weird 1/2" tube attachment.

The D5 non-Vario (fixed speed) runs at the equivalent of the Vario at speed 4.
