I thought about it but wasn’t sure. Maybe it’s coil whine coming from the DC plug. Bought the board end of October so I cannot return it anymore. Any tips on how to improve it? Still it’s strange that it’s only doing it in Unraid. In Opensuse I tried to push the system but there was no sound, it just worked. That’s what throws me off.
Also posted this above to a previous poster but you won’t be notified so I will post it here as well.
Unfortunately it doesn’t say in the manual. It only says that if you use 4 HDDs you should use a 90W DC 19V power brick. I already ordered one, my confusion was if the 4 pin cable supports 2 HDDs but I guess since the board has 2 SATA slots and cable also has 2 SATA power connectors. I plan to most likely use 2x WD Red Plus 8TB, they use 6.2W (load), 4.1W (idle)

I also like the case and since the motherboard has power integrated and the CPU is in theory passively cooled, it will be quite empty since I don’t have to stuff a PSU/GPU inside it. Initially, I wanted to get the Fractal Ridge but it was to long for the opening in the cupboard where it was going to sit. The SG13 seemed like the best choice, size wise and the 2 drives fit good.
I am planning on putting a 80mm fan at the back which would bring somewhat limited fresh air and on the front a 120mm fan as exhaust to remove heat from the mobo/hdds.
Thanks for the tip! For some reason I was searching for a similar but longer cable to the one provided but never thought to look for a SATA power extender :).
I’ve heard about avoiding the injection molded ones but I wanted to ask you, is it safe to power the 2 drives directly from the motherboard? The board has 2 SATA ports and the cable that comes with has 2 power SATA connectors so it should not overheat/burn the cables if they give you the option to use it?

I live in a constant fear of batteries catching fire, cables melting and other bad things happening when it comes to power :). That’s why I tend to only buy original batteries, cables, power adapters.
Thanks, I changed something else, before you replied and forgot to update my reply to you, but I updated the main thread. Maybe some else will search for this exact problem so they know what to do.
So because I did not want to leave Turbo Boost off, I did some more digging and also realized my CPU was always boosting in Unraid. using “watch grep “cpu MHz” /proc/cpuinfo” it was almost always between 2900Mhz and 3300Mhz. I installed Tips and Tweaks plugin and set Normal CPU Scaling Governor to power saver. The sound is gone and now it seems the CPU goes all the way down to 600 MHz and up to 3400MHz depending if it needs it. I don’t know if the power saver will affect performance in any way but so far so good and I don’t have hear that wheeeeee anymore.
