Obsidian 750D 4K Watercooled Build

Recommended Posts



Haven't bothered with a proper photoshoot yet. Still need to clean it up some more. Something about it... I'm still not happy with.


I actually completed this initial build at the very beginning year as soon as the X99 platform was released. This thread will show photos of the systems initial build to where it is today. I just finished redoing the cooling loop. Please enjoy and feel free to provide any feedback or opinions. I'm always open to suggestions and learning new things. The intended coolant was Mayhems Pastel Blueberry, but I'll be draining the system in a couple months when I return to the US.


I do have some future plans. I'd like to upgrade the RAM to something else, but haven't quite gotten to that point yet. Corsair's Vengeance LED RAM looks attractive as long as the LEDs remain steadily lit and don't do any funky effects. I might also just get some more LPX and throw on some waterblocks, but I'm left unsure of this memory as my current DDR4-2666 can't even achieve the XMP2 (DDR4-2800) profile anymore even with very relaxed timings. I was able to achieve 3000MHz for quite a while @ 1.35v. Not sure why it's losing performance. My fill/drain system has plans, but parts lost in shipping have put those plans at a standstill. My intention is to allow filling and draining without moving or opening the case.


I'm still a bit unhappy with the cables that are under the GPUs. I'm considering different ways of organizing them better.


My last build was in an Air 540. While that case was nice, it was a bit too much plastic for me and I'm a huge fan of brushed metal finishes. Thread: http://forum.corsair.com/v3/showthread.php?t=127215
