As a person that was originally sold on Louqe Ghost S1 mkII, then once again impressed by concepts of C4-SFX...
I have to start with this...
Already increasing the watercooling chamber to 55mm was quite unnecessary. 46mm is plenty enough, it allows for 30mm radiator with 16mm fans, or 25mm fans with 20-21mm radiator. That was already adding 0.37L.
You have to realize not all of the supporters of this project aren't pc modders. Fiddling with radiator sizes and fan sizes aren't something that not all supporters can do. AIO(All-in-ones) something non-modders can't fiddle around with usually START with 25mm thickness on both the radiator and the fans. Going out of their way to change fans to fit the cases doesn't seem ideal in a way that it costs money and we are potentially risking our temperature in a nonfavorable way. Furthermore, by the limited chamber, we would be limited in
options.
2x120mm radiator is not a good idea. The CPU will run hotter, the GPU will run hotter. It's better to have a 240mm AIO for the CPU, and use the GPU on air cooling as it's presented in a much more compact format.
I still don't understand those who want to make a custom loop in it, and wanting design changes for it. Isn't the whole point of making a SFF custom loop the challenge, and personal modifications of the case? The main reason to get an SFF case is to make it more portable, and of course having it take less space. With a custom loop the SFF PC loses it's portability.
I'm not sure if you ever tried putting in an AIO on a GPU before, but the temps are VERY (I mean VERY) significant. We are talking 50-70C to 25-40C depending on how well the air circulation is in your system. I personally used this extra temperature room to fiddle around with the card itself to overclock and whatnot.
Also, of course the CPU may run hotter by using an 120mm AIO than 240mm AIO. Thats just straight up radiator size differences. But heres the thing, it leaves us with options to prioritize which part (CPU or GPU) cooling performance we want rather than having no options at all.
Something that Louqe Ghost S1 mkII would lack.
If I were to say this in a polite way, just because you might like one method than the other and won't affect your build, it isn't a reason for the case to have more options to cater to different builders. Let just not run around with our egos and hope to push one person's ideals onto a project that is hoping to serve many.
Last note, you are right about SFF being all about portability; however, its a fine line of balance of people who want performance (which correlates to temperatures) and portability at the same time. Once again, having options is better than no options.
There's already been compromises on this, because people wanted to be able to use 30mm radiator with 25mm fans. And now people want even more compromises? Very possibly making it larger of a case than the other already existing options.
In the end, it's the designer/engineer's choice. The choices he make comes from a different perspective. (The perspective of hoping to creating something that sets it apart from everything else and making something (not all) but at least some of the SFF community members would appreciate.)
Let that sink in a little...
and not jump to conclusions and bring bad vibes into a project forum that I have been very appreciative of.
EDIT:
I forgot to add some other perspectives why C4-SFX sets apart from Louqe Ghost S1 mkII.
When it comes to SFF cases, I consider the "wasted" space.
And what I mean by that is, unnecessary space inside the case that would serve absolutely no purpose. While the increased space for cooling chamber would increase, it would give compatibility and options; however, wasted space would be worth nothing.
I seemed to see that a lot for Louqe Ghost S1.
Even without looking at it and just numbers alone, why is the case 11L when it lacks options, while C4-SFX can do that in 10L with options?
In the end, I see Louqe to be more roomy to make builds and cable management easier, while lacking other compatibility and options.
I think the cooling compromises that
@dondan made for us is very significant. As well as giving us 2.5 slot option for bigger cards (more performance). All under 10L, I'm a happi boi.
