it looks very cool! I wish more manufacturers made fully silent cases utilising the case itself as a heatsink

[@godsinbox]

well, maybe you want to take the sides off? will someone think about the thermal paste!

[@kasimirdenhertog3516]

What a coincidence, I’ve built many systems in my DB4 and have just finished a new one (after having it on a shelf for about a year), then this video shows up! Very interesting to watch someone else build with it, the case is fiddly to work with but the results can be really rewarding. In my DB4, I now have a 8086K, 64GB RAM and a RTX 3060 Ti. It also features an Intel Optane 905P PCI-E SSD, this was the reason for the build, since I had worked out I could use a M.2 to PCI-E adapter and just about mount it on the PSU side. In my configuration, I use 1 panel to cool the CPU and 2 for the GPU, using a special kit from HDPLEX with 8 heatpipes. I can bore you with a lot of other interesting info, but that would be a bit much for a KZbin comment 🙂

[@kasimirdenhertog3516]

One question though: what thermal paste are you using and why? I’ve had quite a few, but some are too stodgy and others are a bit runnier but grainy, or they will dry out quickly. I’ve mixed one with a bit of solvent, which seemed to work quite good but of course isn’t ideal.

[@fullysilentpcs]

Interesting! I hadn't thought of using the HDPlex GPU kit, but I'm sure it would work well. That must have required a lot of heatpipe bending. Theoretically you could use 2 panels for the CPU and two for the GPU, but Streacom doesn't make that easy to do.

[@fullysilentpcs]

I'm using Arctic MX-5 because of its good performance for its price and because it is fairly easy to use (though it is very sticky). I also use their MX-4 often.

[@kasimirdenhertog3516]

@@fullysilentpcs I've actually tried this, with the GPU side also routing heatpipes to the back. But it isn't worth it, the length of the heatpipes to the back are quite long and the panel just doesn't heat up like the other panels do. I've also had the GPU and CPU sharing a panel, but the effect of this can be the GPU heating up the CPU.

[@kasimirdenhertog3516]

@@fullysilentpcs OK, I've been using mainly Thermal Grizzly and Noctua pastes, they score top points in reviews, what do you think of those?

[@Rakadis]

What a beast of a computer. Especially when you consider the no noise aspect. Ever have any problems with coil-whine when building silent PCs?

[@fullysilentpcs]

Yes, it does happen sometimes. If it is easily noticeable I will return the affected component. It is most common with higher power GPUs, and sometimes power supplies. Sometimes underclocking or undervolting will help.

Very very interesting! A video like these for the H5. Maybe my next build... Greetings from Germany

@@fullysilentpcs Sorry Mat. It`s my fault. Maybe I had better wrote " A video like the one for the H5". The H5 is my current PC (You inspired me with your video). The Streacom could be the next...

[@fullysilentpcs]

Ahh, I see. Well, the H5 does perform a bit better than the DB4, so I wouldn't trade unless you really like the look of the DB4. If you care most about cooling performance, Turemetal and MonsterLabo both have newer cases that perform better than the DB4 or H5.

Good video, but the music was really uncomfortable

[@drewcook6340]

Thank you for making this video. This really helped get a strong handle for what would be involved in taking one of these on. Do you mind if I ask you how long the build took you?

[@fullysilentpcs]

I think this one generally takes 4-6 hours.

[@drewcook6340]

Thanks for sharing... Can you please tell what is the highest safe temp for PCH? With 22c ambient room, mine reaches 50c with 2 intake at 650rpm if I turn them off PCH reaches 69 on ZZEW B6 14L mini itx case, Gigabyte Aorus Z690i lite d4 (with 2 gen4 NVME SSD and 2 sata 2.5 ssds, i5-12400+Thermalright SI-100 210TDP rated 31-47c and 56c highest with no fans; GPU is a HP AMD RX5500 oem replaced heatsink with a Raijintek Morpheus 2 Core no fans 32-40c normal use and 57c gaming) is 69c or even 70-75c degrees ok for PCH? Thanks before hand!

[@Z4KIUS]

looks like it's a compromise between build complexity and efficiency, it would be really helpful for unbalanced load scenarios if both CPU and GPU were routed to all 4 panels, but building that would be a nightmare for sure, or at least 3 each, that looks like a hard time too but still much easier it also needs a modular PSU for sure that aside, do you have temps of the panels themselves? that's pretty important matter for this kind of builds after all, P1 can get painfully hot but is safely enclosed in regular case so it's a non-issue, how is it for this one?

[@MassDynamic]

heatsink hard to clean?

[@andreasschaufler]

Hi, really interesting build. I am working with the DB4 myself trying to find out how much heat it can extract. I did plenty of customization connecting the CPU to 3 side panels. (Not using GPU) But still I see it throttling in a torture test when it is around 65W after like half an hour. Side panels are heating up quite nicely in my case though. 65W is measured actual power consumption during the run. In your video I see you are plotting temps against power limit. Wonder which of the power limits you are setting ? My case is AMD so it is hard to compare, but I wonder how much the power CPU in your case is actually dissipating. Very good hint to increase the pressure against the sidewalls using the screws. I switched from the pads to paste for the side panels, but I did not do any extra effort to increase the pressure of those. But I’ll definitely try this. Feel free to get in touch if you are interested to discuss more. Thanks a lot.

[@fullysilentpcs]

It was Intel's PL1 that I was adjusting, and it matched the actual power use during the stress tests. I do recommend trying to increase the pressure against the heatsink panels.

[@andreasschaufler]

@@fullysilentpcs thanks for the reply. I must have issue with the thermal conductivity to the sidewalls then. How hot do you see the side panels in your case? I am up to 47C on the front wall directly opposite the CPU. The other 2 see lower.

[@fullysilentpcs]

I don't have a way to measure it, but I am sure that it gets higher than 47 when stressed. It should get hot enough that it is uncomfortable to touch.

[@andreasschaufler]

@@fullysilentpcs ok, thank you that was very valuable input. I am regularly checking in on your channel. Nice work!

[@kasimirdenhertog3516]

I have a lot of experience building with the DB4. The panels can dissipate about 50W each. 65W on one panel is a bit of a stretch, but 2 panels should definitely work, if not, something should be improved about your thermal conductivity (paste/pressure). In my experience, the CPU block from Streacom requires a lot of paste to work properly, so that might be an issue apart from the connection to the panels.
