Behold,

my first eva custom loop:

https://gofile.io/d/NEe5qv

I am very proud of it despite the bends being far from perfect and i was free styling with design tryimng to have as much fun as possible and gain experience with hard tubing. It has been both dry/wet leak tested, bled and cycled for several hours. So far I have not put any strain on the system to test efficiency as i am still finishing it but temps are looking steady (from 4 ambient air sensors).

The components are:
- 2x EK Coolstream rads
- EK Velocity CPU water block
- EK Vector GPU water block
- EK O11 XL distro plate for Lian Li ROG case

Feedback welcomed!

Cheers

Looking good! Very neat tubing runs for a first time. Really works well with the red fluid too.

I can see quite a few of the bends have been pinched a bit so they deform. Did you use a tube insert while bending? They don't look so extreme as to restrict the flow, but worth bearing in mind for future tubes. Plus when you put all this work in, you want everything perfect!

How are component temperatures and noise looking?
 
Thanks! Yes, you are right there are some kinks particularly on the GPU inlet and CPU outlet. There is couple of reasons i think. Some of the bends result in deformation cause the tube was not heated enough on a long enough part. I found that i prefer to feel some resistance to better control the bend so i was quite conservative with heat gun action. Some others I had to correct when another bend down tube was already in place (CPU outlet) and thus I couldn't squeeze in the silicon insert. I tried to have it in whenever it was possible. I think they are cosmetic and without impact on the flow of coolant. Next time i will remember about this and try to do it differently.

Noise levels are very low. The distro pump is very quiet but I have spent some time in shaking the whole chassis lol to get all the air out. Right now I can only hear fans. Temp behind distro is 1C above ambient, above bottom fans 2C above, next to CPU 1C above and exhaust 2C above ambient. I don't have it yet finished to fans are running around 1500 rpms as I need to tweak my RGB/PWN set up. Once i get that sorted I will be able to say more about noise.

Ah, I usually rough cut the tube and put the silicone insert in from the other end in that case. Yes I've had the insert stuck more than once in multiple bends!
 
I try to do that but it not always was possible. When i had a 90 degree bend in place it was still doable but when two were in place i couldn't squeeze it in (like the distro connection with CPU outlet line).
 
Thanks mate! I have noticed one mistake I made. The CPU inlet should tube should be the one closer to the center of the block and i did the opposite. I will have to revert this at some stage.
 
I did play Metro Exodus on ultra for 30 min to see the performance of the loop and cooling in general.

CPU was 55-58C, GPU was 55-60C, SB was 55C MB, MB was 35C, VRM was 38C. I had fans at 2000 rpm but without temp curve set up so cant tell if it was necessary or not. When I had them at 400 rpms temps were going up.
