This mobo has a 4-pin connector for the chassis FAN that is not listed in the manual. However, when I connect a chassis fan to that connector, the fan always spins at full speed. Does anyone else have the same problem?
I plan to purchase and install a fan controller.
An additional 10GbE card was purchased to be installed in the M.2. This works very well.

That's what I am saying on my previous message : the fan is completely running at max speed for me too so that's why I have contacted the brand. I talked to someone on whatsapp who told me she would talk to the engineers... Maybe are we going to have a BIOS fix, but I think you should also contact them : the more requests they have, the less time they will take to fix this problem
Admittedly I didn't test it with any fans connected outside of the heatsink fan, so I don't know about the PWM functionality. In 2 "U-NAS NSC-810A" I run ATtiny's to regulate up to 7 fans with PWM, I don't trust onboard fan regulation (especially from Supermicro), too many let downs :-/.
Sadly, I doubt the BIOS will be updated. That said, there is a few comments on Aliexpress stating they they emailed bkipc and they emailed back, so maybe try it once.
If you're interested, I'll post the code I edited for the ATtiny below, I found it on github somewhere. Also, you can buy little pre-built PCBs that are through hole or SMD and solder on the components yourself.

Thanks for your reply. Sorry but I am not sure to understand... Is ATtiny's a software ? Or a Arduino controller ? (according to google)

I also got this mobo and was also annoyed by the chassis fan running at full speed (even with PWM).
From my tests, smart fan seems to work approximately with PWM on CPU fan so for now I connected PWM fan on CPU fan port and connected CPU fan on this fan forwarded port.
Have you had any experience with using one of the m.2 to PCIe risers? I’m curious how that might perform with the 9207, and if it’s worth the power draw over the 1166 based 6port you used earlier.
The 585 seems like a bit of let down. And from what I’ve watched the 5105 board from the same doesn’t have nearly as slow of onboard sata connections.
m.2 to PCIe risers? I’m curious how that might perform with the 9207,
It would be single lane performance at best, but isn't that enough? With any of these low powered boards you'd want a SAS HBA that can accept independent power. I mentioned in this write up that the M.2 to PCIe adapter I used would not power the 9207-8i, so I had to use a 9300 which accepts independent power via a 6-pin 4.2mm/PCIe header.
If you want fast permanent storage, you should not be looking at anything like a N100 nor without at least RDIMM ECC. These low powered boards are not broke out for super-fast PCIe TX/RX.

You just need to look for a motherboard with better connections. The Asus PRIME N100I-D D4 motherboard has a true two-lane miniPCIe 3.0 connector. That gives you a total access speed of 1970 MB/s, more than enough to connect 6 rotating hard drives and never reach the limit no matter how fast they are. If you use SSD disks and do not want to have bottlenecks, do not connect more than 4.
You can see the details here:

Do you even bother reading what people actually write?
Of course. Why do you need a riser if a miniPCIe port can already do the job?
You just have to look a little further...
look a little further...
Maybe just look...? Why do you think people look at this BK board?
I don't use this BK board but, I also don't understand why you bring up the Asus's x2 lane miniPCIe in context of storage. The Asus board has a SINGLE GIGABIT port, so, 127MB/s is the best it does. In this regard, the BK makes the Asus look silly, almost like a bad choice for storage :-/.
Can you prove that _any_ SAS HBA (v1, v2 or v3) 8 ports or less can operate in x2 lanes? I've never tried it and it's not that I would be surprised if it did work, it's that I wouldn't be surprised if it didn't as SAS controllers fallback from 4/8/16 SAS lanes to a single SAS lanes. Of course, SAS lanes are not PCIe lanes, but they very well might be physically wired out that way.
While this proves nothing about the x2 performance of any given SAS HBA, it does suggest that the controller is designed around 1 or multiples of 4. I used the model in discussion, the 9207. I simply don't have an extra device on hand that supports x2 PCIe to test the performance of the 9207-8i.
Why do you think people look at this BK board?
I don't think people look at this board much. He is more prepared to configure a router than to configure a NAS. There are many ways to add a 2.5GB network port but few ways to fix the poor performance of that board's storage ports.
But hey, each person decides what they like or need the most. Surely if you bought it you thought it was a good idea for some reason and I am convinced that you are happy with it.

Like any card on this list since the RPi CM4 has a single pci lane - https://pipci.jeffgeerling.com/#sata-cards-and-storage
Like any card on this list since the RPi CM4 has a single pci lane
Single? Do you mean double... x2?
Single? Do you mean double... x2?
Nope. It has a single x1 gen 2 pci-e lane.
From the datasheet - 1 × PCIe 1-lane Host, Gen 2 (5Gbps)
Nope. It has a single x1 gen 2 pci-e lane.
I'm confused. What's the correlation between that list and a SAS HBA operating in x2 lanes?
I also don't understand why you bring up the Asus's x2 lane miniPCIe in context of storage.
I suppose this table can be useful to understand it.
Source: https://en.wikipedia.org/wiki/PCI_Express
Cen 3.0 and x2 -> 1.969 GB/s
There are no ports with more than one lane on the BK board.
I'm confused. What's the correlation between that list and a SAS HBA operating in x2 lanes?
You asked if any HBA could operate in x2 lanes. I gave you a list of HBAs that work in x1 lanes. If they work in x1, they will work in x2.
OK
Hola.
Compré esta placa base pero no encuentro el manual.
¿Alguien puede ayudarme con las conexiones positivas y negativas, led HDD, power sw, power reset, led + y led -?
Estaré muy agradecido.
