The 50 liters cheese grater you mean?


Ah conceptually, ok then, thx! ;)
Yeah, 3 fans forcing air across passive heat sinks in a shallow case. Sort of brilliant in its simplicity and seeming efficiency/efficacy.

Really nice, well done! :thumb:
It looks like you know your thing about video capture.
First time I hear about trifurcation, didn't know C_Payne was also making such cards.

I see you drilled some holes into the Makerbeam frame, threaded as well I guess.
I will probably do that once I am set on a final version of the prototype, should make it look cleaner without so many brackets.

May I ask how you have secured the PSU?
And what did you use for the 3D printed panels, ABS or PLA?
MakerBeam has thread-forming screw kits. Works like a charm.

The PSU is secured in two ways. The first way is with a printed bracket, which is held by the makerbeam frame; you can see two screws on the PSU holding the PSU to this bracket. The second way is from the bottom, which is just a hole cutout of the bottom printed sleeve, which is holding it in place with friction.

I printed it in PLA. Seems to be working fine.

Ok so in all my slowliness I even managed to move forward!

Have a look at the PSU installed into the frame, with my dead Z77 Asrock motherboard under it for fitment test:


I have then added my not working GTX760 also to see how it fit, along with my cheap PCIe riser, but noticed a little issue.
The back part of the DVI connector is squared on this graphics card (as well as on my working 760), not at an angle as how I had in my sketchup design.
So, for about 1mm,this rectangle DVI connector is going to interfere with the bottom of GPU heatsink (represented by the ruler):


Next I have finally unwrapped the core of the system, the heatsinks! Check how gorgeous they are:


GPU side:


While I have been able to get the GPU heatsinks at their correct dimensions, this was not possible with the CPU one.
So I had to cut it at a length of 170mm but this distance (small black dot) was not appropriate with the way the heatsink was going to be attached to the frame. I indeed need an heatsink 'teeth' to remain on its side, so I have cut it a bit bigger:


Of course, this little adjustment and my almost zero tolerance design have leaded to a new issue. The heatsink did not fit anymore into the frame:


So my only option was to move the bottom fixations a bit down, hopefully still leaving enough room for the cables going on the motheboard I/O.
This correction made me redo the motherboard standoffs as well as the GPU heatsink supports, which I made compatible with the squared DVI ports.
Two problems solved!
Both heatsinks are properly installed now:

Waiting for the PCIe riser to arrive, I hope having ordered the right one, long enough but not too long.
Still have to order the fans and find what to take for the side pannels.
But the next big step is preparing the copper block that will take place in between the GPU die and the GPU heatsink.

You had me from the full frontal fans pic. The rest is just lascivious. :p Want one.

This is a fantastic project :D

On a different note - I was looking at the alpine passive cooler for the AM4... 99x99x70. I need to use your calculator to see if that'll cover a ryzen 5 1600 :D

Passive that cooler is good for 43w, per the manufacturer. Not sure what the rating is if it has airflow or not but 65w with some flow might just do it.

Interesting. The calculator he quoted marked it as properly sized for ~160W with "some but quiet flow". I'd be curious to what extent and how directed it needs to be. Granted, I may have missed a possible assumption that a vapor chamber would be involved.

Thanx a lot!
The calculator gives really rough estimations, as you noted especially because of the difficulty to quantify the airflow amount. Hopefully I will be in the right range.
Let us know how it goes with the Alpine cooler if you give it a try.


ADT R33UF-TU riser has arrived!


To check if it was working and if I took the right length made me install the working motherboard and GTX760 on the Makerbeam frame:

It works!
Length should be ok, however this riser is kind of stiff and it is currently pushing the GPU to the outside, that's why the GPU snags a bit on top. I will probably have to guide the riser to make it get a nice and smaller curve before it goes in between the two cards.

Prototype post updated.

Ok I couldn't resist!
With the hardware in place I had to quickly test the Streacom HT04! XD

I have just put some thermal paste that came with the HT04 on top of the CPU heatspreader, and nothing between the HT04 and the heatsink.


There is a tiny visible gap on the lower part of the HT04 where it doesn't touch properly the heatsink even though I tried to adjust the latter.
I will probably sort this out when doing the proper installation, but anyway both the thermal paste and the vapour chamber will take care of that.


I of course started the system to the BIOS and let it run for around an hour.
In this passiv mode the CPU temp went from 30°C to 55°C, and would have likely gone higher if I had let the computer run longer.

A quick test at the end with my laser gun showed me the HT04 pipes were at 48°C, which was nearly the same on the heatsink around the HT04. So the contact without thernal paste was not that bad actually.
The temps were much lower on the corners of the heatsink, from 30°C to 38°C, so I am hoping the vapour chamber will be of great help here in moving the heat.
Oddly enough, the top corners were around 30°C while the bottom ones were hotter at 38°C. I would have expected the opposite as the heat is supposed to go up.

Now back to that GPU copper block...
