Part IV: Tube Runs and Leak-Test
So here is my newly revised flow diagram for a single-loop run in series with the koolance RES:
So basically this will unify the reservoir with both loops using a common water source and share the radiator load across all components. I would have preferred to mate the smaller RX120 radiator with the CPU block and the RX360 directly with the video cards for cooling proximity, but I don't think it would affect my temps by any large measure as it is right now.
1. Filling and Leak Test
Ok so for those of you planning on using the Koolance 45x series Res/Pump with two pumps - The reservoirs in front are the opposite of the markings in the back
! This is not in the manual and was a ***** to understand and plan the flow. To add to the trouble - the included short and long plugs that either unify or segment the two reservoirs comes with no instructions for when to use them in serial or parallel operation.
I made the mistake of using the short plug and the water flow was turbulent inside the RES. In this setup - you HAVE
to use the long plug to segment the water between the pumps.
After figuring that out - Koolance does a good job with top and front filling ports. The best way I found to fill this was with the pc on its back, RES on top and using the front fill ports on the right reservoir (Pump2). Since the inlets/outlets on the right RES are much higher than the left one, the water level needs to be pretty high to circulate water in series - since it continues to go down everytime you upright the computer.
I used my wife's turkey baster to keep the water-level high enough while cycling pump power and rocking the unit to get rid of air bubbles. After a lot of trial and error - this was the best way I found to work. I let that run overnight and put some PT nuke in the morning and closed the plug up after checking for leaks.
2. Lights On
So a few things about the HAF-X:
The bottom location of the RX120 RES was almost perfect. It was close with the AX1200 PSU as it is longer than a traditional power supply but there is a vent right at that spot to provide pull function airflow right into the case. That work out really well. Obviously cutting the HD cage you can fit a 240 for sure, I wanted to minimize my case modding.
The EK SLI bridge requires you to remove the fan shroud from the side-panel, obviously not a big deal if you're WC but an issue nonetheless.
Looking at the front of the case shows in order to fit the 360 rad up top, Blu-Ray drive, Fan controller and the Koolance 2-bay RES, I had to remove the 2 bottom hot-swap bays to make room. No loss for me since I used the internal HD cage, but this may be an issue for others.
Here is the final shot with the PC on after all the new mods. Next up are LED lights for the RES, cold cathode for case lighting and cable sleeving. I'm considering removing the quickdisconnects as the split RES, series single loop makes it not too functional to drain the loop tbh.
