First Pc Build, need opinions on parts and help with watercooling

DiesHorribly · Nov 15, 2015

Hi Community,

I am trying to build my first PC and would like some recommendations and opinions on the components. I have been looking at different builds and parts for about 2 weeks and revised my list for the 3rd time now

Partlist on Partpicker: http://pcpartpicker.com/p/wmHp6h

Mobo: Asus Z170-A ATX LGA1151

CPU: Intel Core i5-6600K 3.5GHz

GPU: EVGA GeForce GTX 980 4GB Superclocked ACX 2.0

RAM: HyperX FURY DDR4 16GB 2-Kit 2666MHz

PSU: Corsair RMx 550W 80+ Gold Certified Fully-Modular ATX Power Supply

SSD: Samsung 850 Evo Series 120GB 2.5" Solid State Drive (Operating System)

HDD: Hitachi Deskstar 7K4000 4TB 3.5" 7200RPM Internal Hard Drive

Wlan: Asus USB-AC56 or Asus PCE-AC56

Cooling: Custom Watercooling loop from EKWB (specs below)

I plan on wall mounting the rig like this:

What do you guys think? Any big mistakes or Compatibility issues?
I will use the System mostly to play Singleplayer, Stream Movies and Tv and do some light office work. I don't plan on overclocking just yet but would like to keep the option open for the future.

Now to the Watercooling specs:

Reservoir & Pump: EK-XRES 140 DDC 3.2 PWM Elite (incl. pump)
Radiator: EK-CoolStream CE 280 (Dual)
Fans. Two EK-Vardar F1-140 (1150rpm)
Custom Waterblocks for CPU and GPU (Acetal & Copper)
Tubing: TUBE PrimoChill PrimoFlex™ Advanced LRT™ 15,9 / 11,1mm aprox. 3 meters
Compressionfittings: EK-ACF Fitting 12/16mm
Coolant: Distilled Water and a Silver Kill Coil

I was thinking of doing a rather simple loop: Pump>GPU>CPU>Radiator>Pump
did I forget any important and/or good to have things?

Now to the final question: Will the pump and radiator be enough to keep my system cool?

First off, that is NOT a suitable build for a first-time build. For one thing, the guy did some additional modifications to move the GPU away from the motherboard )at a minimum there was some PCI-e Extender there, but those things get tricky and it messes with lane timings on the PCI-e.

Secondly, did you happen to notice that rig has two pumps and two reservoirs? Using one pump and one circuit, it's always a robbing Peter to pay Paul type setup. Do you take the warm water from the GPU to cool the CPU and lower thermal efficiency on the CPU or vice-versa. One will suffer - it's your call which one you hate most.

Hi Karsten,
I knew about the extra modifications to the PCI-e and am planning to buy a more expensive shielded PCI-e cabel.
(i knew it might be a bit of an overkill with the wall mount, that's why i'm still in the planning phase and didn't buy any parts yet. but i like the challenge)

Would the pump be strong enough if I added a second radiator, but make the second only single and not double faned?

The thought of tag-teamed radiators occurred to me as well. (great minds think alike!). Like you, however, I do not know the impact of that on the load on the pump and the resulting flow rate through the radiators.

You may have to ask the question in a different thread.
