IDK if that is really reasonable, since the air gap between the feet underneath the chassis does not contain any hardware. @Aux set up the rule with the volume calculation, so lets see what they have to say about it.
Looks like it is bounding box, as your volume is adjusted to 6.94L in the above post...
@Aux , might we get a ruling on decimal places & any rules for rounding up/down...?
The dimensions of the case, if you look at a number of reviews, take note of such extrusions.
The dimensions in the advertising also typically note with and without protrusions.




For a number of these cases, if there were no airflow through the base of the case, the system would overheat and so the feet make a difference.
(see above for ventilation to case from underneath)


The case volume has a significant impact on the performance figure. Currently I round up to two decimal places.

At the end of the day, its up to us to decide if we want to do it one way or another. Im easy on these points.

In agreement, was just wanting to clarify the volume measurement, as the gentleman with the MI-6 was measuring his chassis box volume, then adding the volumes for four individual feet...

Case is the CCD MI-6 by Firewolfy
Exact dimensions are w/d/h 203 x 135 x 248 mm with 4 feet (20 mm diameter and 5 mm height each)
Total Volume: 6.79644 l + 4 * 1.57 ml = 6.80272 l
Now we know, bounding box that includes the feet & all airspace the bounding box defines, which makes sense...

Моя система построена на Dan a4. Могу с уверенностью сказать, что он будет первым при переходе на 3950x. Пока на 8700t он выглядит как этот процессор 3041 GPU 14708 DAN A4 7.25
((3041x14708) / (7,25 ^ 1,5) / 100 = 22912

Hi

@sancho

can you add the cpuZ and gpuZ to the screenshots please

thanks

this is your build from
"The most powerful water-cooled assembly with two rtx 2080ti in one casing" or?
This currently only has one rtx2080 or?

Yes, his is my assembly. Today I will add screenshots with cpu and gpu-z.
Yes, these are the results for one 2080 ti at the moment only

I LOVE those tight water-cooling-loops. Very well done, and kudos for your engineering and pc-building-skills!!!
Also, I'm looking forward to see your SLI-Solution, as you'd need a custom NVLink Bridge, and I'm curious to see how bifurcation works in modern times.

Good luck with the 3950X, I hope it doesn't melt anything inside your case under full load.

At full load, this system does not heat up above 55 degrees. When switching to 3950, I think that the temperature will not exceed 65 degrees
I7 8700t consumes 80 watts in load

Well, no problem, give me the stress test detail, I'll do it. :)
The computer and AIDA 64 are completely covered by covers. You need to check the settings of the CPU, GPU, HDD - 30 minutes and that’s all (I think the processor will start trotting)
Then I will do the same and we will compare the results. I think it will be interesting.

These tests do not load all elements at once. And in order to close the case, you need to cut 2 screeds from the bottom near the radiator

I've no clue what are you talking about. :D What I have to remove? BTW, I don't think there are scenario where will have 2 gpus and 16core of the CPU on load at the same time :D

Here you are! Stressing 2 GPUs, 16 cores, 2 SSD, NO throttling!!

Yes, I looked at the results of CPU-94 degrees, GPU1-84 degrees (they all work in throttling). It is 35 minutes. Water boils at 100 degrees and turns into steam (depending on height). The life cycle of this system is 0. I do not want to offend you, but my advice will be to find a compromise between performance and cooling quality. Perhaps the radiator needs to be replaced with Koolance or XSPC, their FPI is 2 times higher. Try turning the system unit upside down and checking the system for heat like this.

May I speak about video cards? These cards are not of a game level and use them in 3dmark sacrilege - their nature is the training of artificial intelligence, there they are kings. The difference in performance between 2080ti is 5%, and the price is 200-300%. RTX and V are completely different architectures; they cannot work in one bundle (even if they are defined in win). I am engaged in the development of artificial intelligence and I know what I'm writing about. I wish you good luck and take care of yourself (in this difficult time we have what to read and what to write about).
