Finally got around to completing my first ever hard-line loop. Words can hardly describe the relief I felt when I realized I hadn't unintentionally created a very expensive water fountain after cycling the pump for the first time.
I went for a colour neutral black-chrome-clear theme so I can experiment with different fluid colours in the future if I want to. The limited edition (1 of 100 of this black-plexi design) EK Supremacy Edge water block became the perfect centerpiece for this build, and fits in perfectly with the rest of the parts. Rest of the loop components include a D5 PWM pump, EK X3 250 reservoir, EK PE360 and SE360 radiators connected with Bitspower fittings. The cables are CableMod E-Series sleeved cables. Didn't go crazy with RGB and lighting since I wanted it to give a nice ambient glow but not enough to keep me up at night when I'm trying to sleep. At most, I might add one RGB strip along the bottom to give some light to the GPUs.
Working with PETG was daunting at first, and I was really worried about not having the right fittings, not being able to do the bends I needed, system not POSTing after connecting all the tubing, etc. Luckily it all worked out in the end after many moments where I thought there was no way it was going to work, like where clearances are down to the millimeter. Bending the tubes was actually easier than expected, and the amount of flexibility in it means I didn't have to be too precise when it came to angles and such.
From the start of this project to completion, including months of saving money, buying parts, waiting for delivery, procrastinating etc. took about 6 months. The name comes from the 侍 (Samurai) magnet a friend of mine bought for me while I was in Japan, which now sits inside the case.
Performance and Temps
Didn't strike gold this time with my delidded 8700K. A very run-of-the-mill bin that's happy to sit stable at 5.0GHz on 1.325V and 5.1GHz on ~1.40V. Oh well. Temps at 5.0GHz running AIDA64 are around mid 60Cs average (ambient of ~22C). Haven't tweaked RAM yet but pretty confident I should be able to take it up to and beyond 4000MHz depending on timings.
The 1070s (which aren't particularly power hungry cards to begin with) are ~50C while running Firestrike, both cards boosting above 2000MHz easily with 110% power limit. Since they are using EK's 1080 FTW water blocks, I may upgrade them in the future if I can find a pair of 1080 FTWs for sale. Firestrike benchmark score is ~25,500.
One thing I realized when I was benchmarking was that I needed to include a water temperature probe as part of the loop so that I can control the radiator fans better (compared to just using CPU temp).
All in all, it was a great learning experience. Hope you like it!
