@dondan I'm interested in knowing as well, my rear I/O usb C ports work fine but I've yet to get the front port on the Dan A4 to work. Not sure if it's the port itself or the motherboard's internal header is at fault.
DAN A4-SFX v4.1
- Thread starter dondan
- Start date
Looks like Optimum Tech removed the video. Guessing he's going to update it with some new info soon. Was pretty cool demonstration though showing how to run a 3900x in small cases like the Dan A4.
Yes and the reason unfortunately is here;
"I have removed the recent video on undervolting the 3900X to 1.00V. Although the CPU was not crashing, was showing full boost speeds and 100% utilization across all 24 threads, there is in fact a performance hit as there seems to be some internal throttling happening. Follow up video to come today including performance benchmarks."
Yep, that sucks. Saw earlier on the AMD Reddit his video became quite controversial and key conclusions weren't holding up unfortunately for those of us contemplating cramming the 3900x in Dan A4 or similar sized cases.
If I had to guess, the frond USB-C headers can't deliver enough power. Might be the mobo header causing this.
As it uses the basic USB 3.0 header on the motherboard, this might occur with the normal USB port on the v3 etc too.
Eagerly awaiting your results. I had to unbox and install the only C7G I was able to find recently as my 645LT was giving me strange pump noise issues (air bubbles) even at low pump header RPM. The C7G was a bit of a surprise coming from the Black Ridge before.After I've presented you the previous king in the 47mm height range, I couldn't resist and had to get my hands on the new Cryorig C7G which is a better revision of the C7CU. Completly made out off copper and coated in graphite. In this video I've done just a quick comparison with my results of the Thermalright AXP-100 Copper, but I promise the overview withAsetek 645LT and Alpenföhn Black Ridge will follow soon to find out who can cool down 140W TDP inside this small formfactor most efficiently!Enjoy!
Was putting my hardware inside the V4 today...and that MSI B450i and RX 5700 XT turned out to be the perfect match!
Just amazing to see that Hardware all together inside the DAN A4-SFX! Thought I spoiler my upcomming build-log...I try to upload as fast as possible!
(I normaly don't upload to imigur... )

)Good or bad surprise?
How do temps compare with the Black Ridge using the same Noctua fan?Looking good! Which is it, though? 3600 or 3900X?
I'm soon gonna build in the V4 with a Black Ridge, so that leaves me with space for a 92mm fan that's 25mm thick under the PSU. Is it better as intake or exhaust, given that it's most likely going to be right along the exhaust of an open-air GPU?
Blowers tend to be louder as they use a single higher rpm fan and build up pressure. Though, in a small case like the dan, they do have the advantage of pulling air through the side panel and exhausting through the back of the case. This prevents exhausted hot air to be pulled back into the case.
Was looking for a 1080ti blower card in the past but ended up with my 1080ti ftw3 as blower cards weren't that easy to find (that periode the rtx series launched so 1080's were not that easy to find).
I'd still go for a blower style card if they were up-spec with other cards and weren't so noisy... Most blower cards aren't as high-speced as cards with custom cooler.
Today I got my 3700X, Gigabyte X570 ITX and RX 5700. I plan to test PCIe 4.0 compatibility with all Risers of all A4-SFX generation (3M Riser, Lian Li Riser & ADT Riser). Furthermore I will validate the cooling performance of the Noctua L9a on the 3700X .
Yesterday I installed Windows Updates, Bios Updates and drivers to have a good base line for further testing. I also did some quick Prime95 tests.
Here are some first results
Today I will test PCIe 4.0 and will do more detailed temp testing.

Here are some first results
- In default configuration the L9a is able to handle the 3700x in Prime95 v29. We have a all core boost of 4Ghz and temperatures are 80-85°C
- With the yesterday released Gigabyte Bios update you are able setup fan profiles for the chipset fan. In silent mode the board is very silent.
- I recommend to customize the fan curve in UEFI for the CPU, because in default configuration the fan act too aggressive. I recommend to setup: < 50°C = 30%, < 60°C = 50%, < 70°C = 70% and >80°C = 100%.
Today I will test PCIe 4.0 and will do more detailed temp testing.
Thank you for testing this! Is this with fan duct or without it? 80-85 in Prime is actually good for the L9a, given that the system won't be stressed that much in normal use cases.
Hello All
I'am an Happy user of a V4 from France,
Regarding Usb-C front port I experience problems too, in fact it doesn't work, what I plug into no Windows ding-dong or life sign
The cable I use works well with another computer, phone... ,
The internal port seems not to be the culprit (mobo Asus Strix B450i) because it works good if I use the usb 3 bracket from my previous node 304 front panel.
Sorry for my bad english
Have a nice day.
This looks very promising. I've always loved the look of the A4 and it's compact size, but I was considering waiting for the C4 because I doubted a processor this powerful would run well in the A4, especially with an air cooler.
PCIe 4.0 compatibility would be nice to have over the riser, but I don't think there will be any real performance difference from PCIe 3.0 until we have much more powerful graphics cards, at least not for gaming.
Thanks for the continuous improvements and testing you put into this case @dondan

Every device that like to handle the connection by itself will not work. The reason is that you use a USB-C port on an USB3.0 internal controller that was designed for USB-A.
A USB-C mouse, keyboard, flashdrives and many smartphones will work. But some hubs with advanced features and also some smart phones does not work. For example my Galaxy S9 does not work because there is media controller hub in it that like to handle the connection. On the other side the Huawei P20 Mate Pro works without a problem. On some android devices it help to activate USB debugging. For the S9 there is also a trick. Use the included USB-C to A cable and connect it to the included A-to-C adapter.
In the first step I thought it was a problem of my cable but I ordered different USB-C to internal 20pin cables from different vendors and all of them work the same.
I can say that the next v4 batch that is in production will not have the internal 20pin cable it will have the new USB3.1 key-A connector this will solve these "problems" but will create a new one: The number of boards featuring a key-a header is very low.

My little buildlog inside the DAN A4-SFX V4 is online...
RYZEN 3600 + Asetek 645LT on a MSI B450I and to complete the 7nm goodness a RX 5700 XT!
By the way: the 3600 runs with 1.35v LCC4 SOC 1.1v @4.1GHz all-core Prime stable!
After the manual OC the TDP goes from 65W up to the 90s while the temps are under control!

Ive seen people mention this in a few places, but everyone generally mentions it without specifics. Has anyone done a vid or benchmarks on sff for it?
@dondan, do you know of the best 120mm fan that would fit in the A4 SFX with the black ridge?
