Yeah the fan noise is only noticeable when I push the cards to ~180W, otherwise they idle pretty quiet.

How are you dealing with the RAM limit (32GB)? I had upgraded mine to an i7 but it was unstable so I’m back to the stock Celeron class CPU.

I'm not using octominer MB or CPU. That MB on my octominer case is running everything, it's an epyc cpu with 512gb of dram. octominer is also pcie limited, i get faster pcie lane with this.
