Just posting up my upgrade from my last build, ended up going a full custom loop in the NZXT s340 Elite very nice sleek case, very small though but needed something small cause I'm tight on space in my living room. not upgraded any of my parts from my last build apart from the ram, kind of gutted I didn't wait till now corsair have just released their new LED DIMM's that could of went nicely with this build. As for the water cooling... this was a challenge, went with Acrylic tubing here should have probably used PETG or even easier soft tubing it might of been cheaper and easier to use, but to be honest I didn't find much trouble using the Acrylic as supposed to PETG. I pretty much did the full loop first time only using 3x of the 500mm EK Tubes, I only used more to redo some bends I thought could of been better. But the one part of the loop that seemed to stress me out so much was the tubing going from the CPU water block to the 120mm rad at the back, I used 3 tubes alone trying to get this right, and ended up using the tube I first made that isn't as straight as I would like it to be. I might redo this with some 90DEG angle fittings as suppose to trying to do two 90DEG bends. apart from that there was one more part of the loop that caused a bit of a problem, I ended up getting a leak when I was first ran a leak test, it wasn't apparent at first but started to notice a wet spot around the fitting attached to the multiport top of the Res. I did have it routed differently as to what you see in the pics now. It was coming out of the 280mm rad and then straight into one the inlets through the top, just using fittings (no tubing). I think it was because these inlets at the top are countersunk and using normal fittings just don't seem create a good seal cause they are hitting of the plastic before tightening down.
But as for overall performance from upgrading to a custom loop I don't see much difference, I still get the same temps I get when I had my CPU and GPU using AIO's, I do get better cooling for my GPU now though with having full coverage and able to get really stable overclocks on my gpu memory, had the frequency up by 600Mhz with 200Mhz boost on the Core Clock, witch I wasn't able to achieve before so really happy with that.
apart from that another thing I need to say is don't put a 60mm rad right next to your cpu lol, this thing seems to build up a lot of heat overtime and having that in your system especially one that is so small is just making my temps creep up quite high, even with my fan speed here set quite high. going to try and maybe add a slim fan on the top of the case to help get some of that hot air out, or even bigger attempts to replace the rad with a thinner one and have this set up in push pull.
But in conclusion I have to say I love my PC lol, even though it has its kinks and room for improvement but that's why I do this, I think once I get the time to iron out these kinks I am happy with my build so far, and I don't think I am going to change these until the next time I upgrade my GPU, so Until then I am totally more than happy with my Aquatic Garden :)
