Cooler Master Cosmos II Mod The biggest case I've ever seen in my life, nice to work with but heavy as %$@&. The case was totally stripped. The case initially had a lot of HDD trays, I've cut all of these out.
Cooling So my idea was to create a sci-fi themed look, with mostly white and gray and minor black accents. With in the front a totally different look, a waterfall reservoir. The helix reservoir is, as you can guess already, for the second loop. So I had some minor bumps in the road as in; how many fittings do I actually need? Well I didn't count yet, but its a lot :9. I saved a lot of fittings over the past year and I almost used all of 'em. I was quite surprised.
I wanted to make a basement for the pumps so they weren't so visible as you see in common builds. The radiator for the GPU is located in the basement as well (240) and for the CPU, which is going to be overclocked obviously, a radiator on top and out of sight (360). All the fans on the radiators are from Bykski, which had a nice aura and actually run on max speed... pretty silent.

Color(s): Black Gray Silver White
RGB Lighting? Yes
Cooling: Custom Liquid Cooling
Type: General Build
#1 - Gathering parts, painting, bending the tubes
Update Build log #1 (14-05-19) - Hardware Assembly Unfortunately I had a few kickbacks in finishing the build. The waterfall reservoir had a really tiny leak on the bottom. So if you've ever worked with the Cosmos 2; you need to get the whole frame clear again to dismount the front body kit. Watercooling loops are all dismounted. I've also tested the RGB (5V) on all the hardware/fans/cpu block. Also I've got a RGB strip for the plexiglass plating to light that up with a custom sticker attached to it (pics will be uploaded later). Because I ordered milky glass the lighting effect wasn't really what I hoped it to be. So I ordered a different/longer strip for more light. This will come at the end of may.
Original case, weighs about 10,000 tons because of the 10,000 trays
Barebone, totally stripped. First layers of primer
Painting the parts
The waterfall reservoir in the making and leak testing
After the paint job, partly assembled
The 240 Radiator with 2 fans mounted in the basement. This was quite some work to make it all fit, because you still need to close the side door on this case. The radiator is about 40 mm thick.
Here you can slightly see the basement, where I flipped and replaced the 240 rad. It had more space now and I can run the soft tubing on the sides to connect on the pass-trough.
Preparing for drilling, pass-troughs are pretty big and need perfect alignment, otherwise your pipes will run inclined/skew and that looks like %&^#
That worked out pretty well...
Here we installed pretty much the whole loop already. As you might see in the basement, it got pretty cozy. I have to re-align the pumps tho, not happy about that yet.
Right side of the case. Will be rerouted in a later build-log episode.
First foto with total water cooling build. Had to remove everything again afterwards :'D
#2 - Solving a tiny leak
(minor) Update Build log #2 (16-05-19) - Hardware Assembly - Still working on the waterfall reservoir. The used glue wasn't sufficient for its purpose. Still a tiny drop escaped through the glue on the bottom of the reservoir. I disassembled the reservoir and removed all the old glue from the surfaces and used a new different type of special plastic glue. This type is water resistant and should do the trick. Going to do some leak testing this evening, I am very curious. - 3 Missing parts are coming in this week; RGB Fan, 1m (digital) LED strip, 2nd temp sensor.
#3 - Working on the ambient effect
Update Build log #3 (21-05-19) - Ambient Effect Allright so we are back in the game. The leak has been fixed on the waterfall reservoir, but it needs some repainting. From all the working the paint got damaged. Also the final fan came in and the 5V ledstrip (Bykski) for syncing with fan RBW. So this got me to the point where I wanted to see what the effect was of the lights. So see for yourself. PS. Case looks really empty now but once the waterfall reservoir is back in, it will go fast with filling empty spaces :D. Also cleaned the 1080Ti and did a thermal paste refresh
So here you can see the impression of the bottom plate. 4mm milky plexi plate.
The complete look so far. Tons of space.... for now
Cleaning GPU and added new thermal paste
#4 - Panels and final loop
Update #4 So, this was quite the ride. What I've done so far
• Fixed the leak in the waterfall reservoir. Proper glue did the trick. • Designed 3 stickers for the panels, attached them and mounted in the case. (Still one missing on the picture) • GPU thermal paste refresh. • Removed small reservoir+mounts in the basement. The horizontal buffer reservoir was obsolete. • Permanently installed the two pumps. • Realigned the connections on the pumps and created 1 drain point for both loops. • Spraypainted the pass-throughs, outer heatsinks on the RAM modules and waterfall reservoir (yet to be installed). • Installed temperature sensors. • Installed sleeved cables on the motherboard and GPU.
Still got loads to do & having fun doing so :D I am think to redo the GPU supply pipe, because I didnt think of the radius in the bend compared to the return pipe.
Pump line up, with a single drain point for two separate loops
Still missing a few pieces.
#5 - Nearing completion
Update #5 As you can see on the pictures, it looks nearly finished. Well not just yet. I'm really taking my time with the build. The waterfall reservoir is finally working as it's supposed to. No leaks detected after 24hrs in both loops. Need to drain the system one more time, so the loop will be clean from small (plastic/metal) particles. Currently only one minor error to be dealt with: the pump for the GPU keeps filling up with small air bubbles. This is probably caused by the waterfall reservoir. When the water drops down it causes air bubbles in the water at the bottom. This is sucked in by the small pump and causes it to make noise. So to solve this I need to make a 'blow-back' where the air can return to the top of the loop, instead of following the whole loop from bottom to the top. Check out the pictures! And enjoy
The waterfall reservoir.
RGB colors, because yes it also has RGB and UV.. the UV will be explained in the next build update.
#6 - Adding/Removing Mayhem UV reactive coolant
Update #6 - Adding Mayhem UV reactive coolant I've added the UV reactive coolant. Although the pics are not super quality yet, you can get the impression already. So I can start cleaning the rough edges and finish the build up to the final build log. I havent really solved the 'air problem' in the GPU loop, it kinda solved itself. Just keep running the loop removed all the air, and the coolant made the water less viscous also. This means the water runs down the loop more smooth.
For next build log; cable management, and some decorations
Update #6A - Removing Mayhem UV reactive coolant Oke, so a small learning point from here on; Mayhem XT-1 Nuke, is NOT compatible with PETG tubing. It causes damage over a period of time to the tube and eventually will crack (Ethylene and PETG cause a chemical reaction over time). So yes, apparently Mayhem is not reporting this on the bottle, only on the website and purchase description. So the system needs to be drained, and I'm going straight back to EKWB EK-Cryofuel. The CPU loop coolant might have had a chemical reaction of some kind, so I had to remove that one anyways. Anyhow, I have no idea how that is possible, after flushing the loop a couple of times before use. All the parts were new except the D5 pump. So maybe there was a small residu in the pump, that would be the only explanation.
So I pretty bumped by this discovery. For now I'm not going back to mayhem brand anytime soon, because these warnings should be on a bottle and not on a %^$# website. This bummer is also a moment to learn more and more about the do's and don'ts :) So we're getting to it and cleaning the loop it is!

#7 - Quantum Cosmos Finished
Hi there again, its been a while since I updated this post but I would still like to share my finished result with you guys. The build turned out quite different than from the first tube runs. I wanted some more juice by switching to a better CPU on the 2066 Socket. So Ive bought a i7 9800X. Also got a EK monoblock and radiator for the CPU, (first radiator was Aluminium, but wouldn't risk the corrosion so now copper). I also rebuild the whole waterfall reservoir on the front side of the case, because the first version just keep showing tiny leaks. The acrylic use this time is 1mm thicker (from 4 to 5 mm) and I used a special glue for practically welding the acrylic. Its been running solid for 3 weeks now, and still no leaks detected anywhere. Also I've changed all the softtubing to hardtubing (PETG) because PVC tubes, also didn't work to well in my system.
Yes, I also started overclocking the CPU to find its limits. I've got it stable now at 5.2 GHz under full load it hits the 85 degrees C. The VCore is on 1.37 so I might be able to reach 5.3GHz, but for now its good.
If you want to check out some benchmark results: https://www.3dmark.com/spy/9024719 If you have never done Time Spy before, go to steam and download it! It actually quite fun to play with those points and try raising the bar.
