Looks very nice, how is the sound level of the fans with this setup?

That sounds great, 'll wait for the one :) thx

Hi,

Yes i love the design, but it works great two. Add Noctua fan on it and it's silent. I have it on the Alpha en Delta , i just like it very much 

Hello, currently I only have the first edition with 16GB of RAM. I was disappointed at the time because there wasn't an option for 32GB, which left me feeling a bit shortchanged.

I need more capacity for my Proxmox cluster. Currently, I'm running Kubernetes, Debian, Kali, home automation, and Selenium bots on it. Each of the three nodes uses about 43GB of RAM when idle. I'm looking to switch everything to a more energy-efficient Sigma setup due to its lower power consumption.

Hi,

What about a Armor case like the Alpha and Delta ?

Hi,

I've identified the issue. It's with the 2-pin to 3-pin adapter: you'll need to swap the cables around.

For the Noctua fan, the black (ground) wire is positioned on the outside, while the red (power) wire is on the inside.

I'm uncertain about the standard orientation. On the motherboard, with the power button facing you, the black wire should be on the right and the red wire on the left. However, the adapters introduce a variation to this arrangement. For the PH 2.0 connector, you should gently lift the pins, remove the cable, and then reinsert it with the positions switched.

Hi,

I'm encountering an issue that I can't quite figure out. I have several PH2.0 to 3-pin connectors, and after testing with a multimeter, I've confirmed they're outputting 5V as they should.

Interestingly, the older/standard fan works perfectly with this setup, indicating there's no issue with the onboard connector itself.

However, my Noctua NF-A4x20 5V fan won't run at all, even when connected via its specific 2-pin connector designed for 5V operations. This problem persists despite the fact that I've verified the fan works in another setup.

Would anyone be able to shed some light on what might be causing this issue?

HI,

I have the NF-A4x20 5V version and there is 3-pin connector to loss wiress no connector on it. 
Because there isn't a 2pin jst ph2.0 connector on it. i just look on the internet for the adapter ..

gr.

Aah owke thank you :)
