I think we will be using an open air frame setup, but I know I would take the 35 db fans at 63C over the 60 db fans at 56C every day.

On GTX 1060 the quieter fans are fine for cooling but I think on 1080's or Vega 56's the only option is to go with high power ones that are loud. I am still waiting for my shipment of 1080TI's to arrive to do some testing with them.

Yes, I think you're probably right there. The higher power GPUs will definitely take stronger airflow to keep cool.

I'm about to contact support and ask if it's possible to modify an existing order to add RAM and a M-SATA SSD.

I think the spacing is a bit too tight for 200W+ 1080Tis so I'm planning on using 120W 1070Tis with this board and continue using traditional risers for 1080Tis.

At the moment we are considering NMB MAT 4710KL-04W-B56 or Delta AFB1212VH fans for the quieter version of the Octominer rig. I will get testing samples in a few days and post results here.
Currently I am running 0.45A Ong Hua HA1225M12S-Z fans that are around 35dB in the test rig 4U case with 8X GTX 1060, mining Zcash with an overclock and undervolt, ambient temperature is 27 C and the GPU temperatures range from 58 to 63 C and it's pretty quiet. Previously I had Delta AFB1212SHE fans, they provided great airflow but were really loud, around 60dB, temps with the Deltas were in the 50-56C range.

If anybody has any other fan recommendations then I am listening

Can you use a 24pin to dual 6 pin (gpu) cable to turn the board on?

Such as this:

Yes, not a problem.

I think comming from a price perspective of $199 is a really good price point considering you get mobo and cpu.

My only concern when it comes to mining is that the cards might not have enough airflow(ofc depending which cards you have).
So with PCI-E risers and cards hanging in the air, you don't actaully have anything that restricts the air from reaching your gfx cards, where as this board will restrict airflow going to your cards from one direction.
I have seen a review of this board on youtube and it looks promising comming from the price point.

I guess with the biostar BTC boards you can at least use it as a normal pc if you want to one day.

Yes, the combined price for a reliable and efficient mobo with CPU is very attractive.
Airflow problem can be solved by adding powerful fans to blow air on them or by putting the mobo and GPUs into our 4U rack chassis case that has 7X delta fans, 4 in the front to push cool air in and 3 in the back to pull the hot air out. Also, if your cards have really thick coolers then it gets tricky, so this mobo works best with cards under 4CM thick.

Can you please explain why motherboard have 5x 6pin PCI adapters? Im read somewhere that only 2 are for mb power. What are other 3? I have plan running RX 580(Use 1x 8pin pcie power connector) on it and need to know if I need 10 6/8 pin connectors or 13 ...

Sure. The motherboard has 5 X 6pin connectors but with most GPUs only 2X 6PIN connectors need to be connected, the rest of the 6PIN connectors go directly to the GPUs from the PSU. You only need to connect all the 5 x 6PIN connectors to the motherboard when you are using cards like GTX 1050 or some other GPUs that don't have 6PIN power connectors on them and draw all the power from the motherboard. So with a PSU that has 10 X 6PIN connectors, you can power the motherboard and all 8 GPUs.

Which two?

Actually any of the 2 6pin connectors is fine. We usually connect the first two.

I think 2 on right side. you have 3 pcie connectors together on left side then little more space and then 2 pcie connectors on right side and this two I think is to power motherboard

We are getting ready to ship the new batch of boards soon. Still have some work left to get them all ready, but here's a short teaser of how the new cooler will look like.

Hahaha, I was going to point out the same. I work in a very safety-conscious environment and I went WTF!

Not my fingers. Grin

One question. How is SSD/HDD powered? Does motherboard have some SATA power output connector(Is cable included)?

Yes, the motherboard has a Sata connector and also a power connector for sata drives. We will include it.

Ha! I told you this question was coming! I'm glad to hear the cable will be there. I may still need to fabricate some adapter for the case fans from the server PSU though.

Good news! We will include the adapter

. 6 pin to 2x molex connector will be included and you can connect the fans with that.
