is a single pump enough to push 2x gpu, cpu, and 2x 420mm rads all in series? also any reason to put your gpu's in series instead of parallel? also did you tie in the temp sens from the res into the temp display on the case?
 
questions aside it looks great!

Running the D5 pump at full speed. Haven't pushed the system so hard yet, but the cooliant stays around max 28C when everything is running in tests programs. Radiator fans stays about 60% of top speed. They are set at 50% from start and controlled by CPU 1 fan header.
 
It's not a big different between serial or parallel on two GPU. The bottom card is always secondary card in SLI and seams always to be not that heavy loaded as primary GPU.

And the temp sensor in the res is connected to the display =). Just had to do that. I'm not interested of the temp inside the case.

Inside my DG-87. It's coming alive at last.


 
More about this project in EVGA Mods Rigs thread over here.

 
Looks awesome!!
 
Remember off-hand where the temp sensor plug is on the case? I'd like to do the same.

You must replace the original sensor with a 10k sensor plug. There is only one temp sensors port.
You could use the original cable with the connector by just cut it in half to have the original 3 pin mini VGA connector or buy a 3 pin mini VGA connector and crimp it on the sensor plug cable. Sensor plug is almost just a 2 pin connector that wont fit.
If you cut the original cable you must do so even with the sensor plug cable and solder them together.
There is no polarity to concern about.

Your build look awesome. I have the same build as you with 2 x 420mm radiator . However my water temp goes up to 36 C when i push my pc to the limit . What is your fan oriation

What is your fan orientation ? and what is your room tempt when you doing the stress test ? FOr me, i have fans blowing in from right and left then air is going out on the top.

They just couldn't make it easy ;). Thanks for the info!

 
This is my temp watercool loop, first one. Frankenloop. Waiting to do my final build once the 1080ti's come out. Looking into copper tube runs, I like a challenge. That and new/better lighting will be a part of it. Cabling will also be upgraded. It's been a fun ride so far!

Top and first rad in the loop has 3x EK-Vardar F1-140 (1150rpm) push out from the case and controlled by CPU fan header. Starts at 50%.
Right side and last rad in the loop has 3x EK-Vardar F1-140 (1150rpm) push in to the case and controlled by CPU fan header. Starts at 50%. Top and right fans are hooked to a PWM hub.
 
Bottom 1x EK-Vardar F1 120 (1150rpm) push in to the case under the pump. Always at 50%. This is made by mod of the case. Need a intake at the bottom and had throw out all HD cages and mounting for these. I'm only using SSD and they are mounted at the back and one NVMe SSD.
 
Left side has 2x EK-Vardar F1-140 (1150rpm) push in to the case. Always at 50%.
Bottom and left fans are controlled by the built in controller.
This create a over pressure in the case.

Room temp stays around 22-23C and I has no OC yet but it will come later.

THank for info. Can you post picture of bottom fan ? how do you mod it ?

You could see pictures of the fan under the pump in pictures that are posted in this Mod Riggs thread.
So the fan is mounted to bottom plate. Had to cut out a cirkel (120mm) to get air in and four holes in a square.
On the fan there is a EK-UNI Pump braket (120mm) where the pump is mounted.
Pump is a EX-XTOP Revo D5 PVM (incl. pump).
