This was 6 months in the making. Some of you may have seen my thread in the modding section where I pondered if a full WC loop would work in the 250D. Well, after hours of measuring, drafting, rendering and planning and months of saving and buying parts a little at a time, I am finally able to present to you my very first water cooled build. Before I get into the build log I will put together a quick and dirty parts list for those who are interested.

The pictures taken here are literally spread out over a timeframe of -months- even though it looks like I sat down and did this in a day, it certainly was not the case! So before I started getting crazy taking pictures I managed to put together a few of the things I would need. Here you can see the radiators, the GPU with the block installed and the CPU block still fresh in the box. Slowly I started to build a collection of fittings. When it came time to start putting stuff together I set up the computer on my crappy old work bench and got started. This was about a month ago. Yes I went a month without my own PC Here you can see where I decided to put the fan hub. Stripped bare. Hey, what's that we have here? Nah, it's fine the way it is. What are you doing? gooby pls stahp Hey it worked! (seriously I wasn't going to do this but I figured "go big or go home" What a nice shiny surface! Let's muck it up. But first lets make sure those electrical contacts are protected during the application Looks good. This was a -tiny- amount of CLU. Barely half a drop. Seriously. A little goes a long way, trust. Well I de-lidded, might as well lap it. Wasn't gonna do this either, but again, couldn't justify NOT doing. I'm so far past the line I might as well keep going. Ooh shiny but hey I must have had a spec of dust on my microfiber cloth and it put a tiny little scratch on the IHS. It shows up on camera very easily but it was a non-issue really. Also shiny, EK Supremacy full nickel OK jumping ahead a little here, the 5.25 bracket is too big for what I plan on doing AND it causes fittings to scrape on it when they are attached to the EK-SBAY. I had to chop it. Honestly I didn't have the right tools for this job but the cost was becoming an issue and I had to make due with what I had. Needs paint Honestly it doesn't look so bad installed Starting to get quite a collection here. Bought a box to organize them. Playing with fitting options. This connection required the most creativity because the I/O hardware is literally right where the bottom G1/4 hole is on this radiator. As you can see, it is necessary to come up and over all of that stuff. One of my many test drops Getting very close to my final layout And this folks is why we can't have a typical tube res layout. WIRES! And with all of those wires right there, we are gonna need a nice shroud. Reused the one that came with the 140 the case had pre-installed. Hey look what showed up It's a very close fit Time to start tubing up! Pro-tips: Lube the tubing ends up with distilled water when putting them on the fittings. Makes it way easier. Also, prepare to have your thumbs destroyed. Get a nice pair of form fitting grippy work gloves. Thirdly, get a hose cutter. Scissors won't do. I used a retractable box cutting knife and just muscled straight through the tubing for straight cuts. Spend the extra 10-15 bucks and get a proper cutter. This connection was insanely hard to put together. It seems whenever you measure, add another 1/2" or more because even if it looks like it's the right length, once you get the first fitting on, the tubing magically shrinks. I had to remove the radiator and put this end of the tubing on because the space was too small for my hands. Next up was the GPU to CPU connection. Be careful not to break your PCI slot when doing this. It actually takes quite a bit of force to squeeze this tubing on and then to tighten the collars. Make sure you use one hand to support the parts your pushing around. Pictured here also is the radiator to radiator hose. This one was nothing special. Just a matter of measure twice cut once, etc. Here you can see what I did for the front radiator. My goal was to achieve the cleanest run possible through this case and I think I achieved that, but it was a pain in the butt! Lastly, the pump/res out to gpu and here you can see the whole layout fully tubed up. I didn't get any pictures of the filling process because, well, I only have 2 hands. Let me tell you though, wow. These DDC pumps, particularly this one, seem to have a hard time with filling. You're supposed to prime the pump before running. No big deal. I struggled though because it kept taking coolant but it wasn't flowing into the pump correctly and causing the coolant to flow when I powered it on. I ended up having to shake it like crazy while priming to let it work it's way in, and filled about half the loop in the process, just trying to get that damn thing to fill. Don't worry, I didn't run it for more than 2-3 seconds when it was cavitated. Eventually, I got it to start pumping and away we went! This is where having a tube res pump top combo would have been real nice. Next time. No leaks detected after an episode of Dr. Who, so towels are removed! That's good. That's damn good. All buttoned up. More exterior pics to come, but as you may have deduced by now, my photography environment is not exactly ideal. Final Thoughts Well, I don't really know what to say other than I'm extremely happy with how this turned out. This is by far the coolest thing I've ever built and I'm very proud of the result. I can't help but stare at it, and shine it up with my micro fiber cloth. It still mesmerizes me to see this in person. The white pastel coolant is fantastic and I'm glad I chose it. It gives a great contrast to the black/red everything else. Oh and needless to say, the fittings look incredible and the nickel blocks are stunning. A LOT of planning and patience went into this build and that is the key to getting something like this done. All told, the only leftover part I had was a single 45° dual rotary fitting so I really was meticulous about everything I needed and only bought exactly what was necessary. This was -expensive- even with penny pinching. A lot of this went into fittings. In a normal case it would not be necessary to have so many rotary fittings, etc, but I needed to make some weird angles here so even though this case is so small, it actually cost more to get it set up than a bigger case. Oh and that bay res costs more than EKs MCP-655 based tube/pump/top combo! "But wait, where are the results!? Temps?! Noise!?" All in due time. Tomorrow I will run a usual series of benchmarks and record temps and performance and post it here in a nice format. For now, it's off to bed with me. I hope you guys enjoyed this build log. I certainly enjoyed doing it!
