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.


I tried to disable c-states and went on a lot of BIOS settings. The sounds is only gone when I turn off Intel Turbo Boost Technology. Then it’s silent but I guess it also kills my performance in Unraid now it shows it at 792 MHz.



Thanks, didn’t know that. That’s what surprised me, if it was power related, I would have thought it’s doing it everytime.


Reading about coil whine if that’s the culprit, it seems a lot of manufacturers don’t RMA them. Just googled a little about the topic and they say some GPU manufacturers accept them. In my case with Asrock, dunno.


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.



When I first started building the machine, I only had the NVMe in the board, the HDDs came at a later date. The sound was still present.


Built a new machine, the moment Unraid is running there are strange interference sounds. Edit: turning off Intel Turbo Boost Technology makes the sound go away.
Built a small machine using an [Asrock N100DC-ITX](https://www.asrock.com/mb/Intel/N100DC-ITX/) motherboard, it has an Intel N100 built in and I also have 1x NVMe and 2x HDDs. The board has a DC Jack so no external PSU. First time I booted it, the NVMe had Opensuse on it so I played around a little, no problem. When I boot into BIOS also no problem. When I boot into Unraid, there is a strange sound coming from the back of the board, sounds like an interference sound. I cannot tell if it's coming from the ethernet port or from the power DC Jack. I think it's from the power. I recorded it with my phone and bumped the sound +20 dB, this is how it sounds like. You can hear the fans and that sound. https://soundcloud.com/user-300866676-719653331/n100-1 https://soundcloud.com/user-300866676-719653331/n1002 For power I tried using both an Intel NUC 65w power adapter and an Asus laptop 90w power adapter, the one Asrock recommends on their website. The system has been running for 1-2days, with 4 containers and Home Assistant VM, it idles at around 16w. Without Home Assistant, it drops to 11w. Any idea what that sound is? **Edit 1**: If I go into BIOS and turn off Intel Turbo Boost Technology then it is silent but also kills my performance? ![](https://lemmy.world/pictrs/image/75559c7b-caca-42a6-94ac-d6de6b74889e.jpeg) **Edit 2** So because I did not want to leave Turbo Boost on, 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.

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? This is the board https://www.asrock.com/mb/Intel/N100DC-ITX/#Specification

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.


The Asrock N100DC-ITX uses a 19v power brick so no separate PSU to power the drives. It comes with a 4 pin cable that splits into 2 SATA power. ![](https://lemmy.world/pictrs/image/c6246430-1975-49ed-851c-a76df2dbc15d.jpeg) The case I chose, Silverstone SG13, comes with a 3.5" HDD bracket but you need to mount the drive belly up so you can screw it in. The second drive I want to put where the PCIe slot is, found a nice 3d model for that. The thing is, the power cable would be too short and the drives would be too far apart to reach both. ![](https://lemmy.world/pictrs/image/1e6e71b4-c5c7-46f7-9f70-8d8b24743381.jpeg) So I removed the HDD bracket and cut 2 L-shaped aluminum stripes and I screwed the drive belly down. This way the cable now reaches both drives. I know, I could have cut the cable and made it longer but I prefer to avoid playing with power cables if I can. Turned out quite good. Wanted to share it with other people. Now I need to find someone to 3d print the PCIe HDD holder and find some rubber stuff to put under the L-shapes to dampen the sound of the drive. This is the 3d model, https://www.printables.com/model/385403-pci-slot-hdd-bracket but V2 with the nice feet. PS the drives in the images are broken so I just used them as dummy drives. ![](https://lemmy.world/pictrs/image/b021cc10-bad0-4e6f-b8de-73b313de06ab.jpeg) ![](https://lemmy.world/pictrs/image/df815343-bb0f-482f-b1eb-4feda7998fca.jpeg) That's about it.

Same with r/antiwork they closed briefly and when Reddit sneezed their way, they opened the sub instantly. Talking about hypocrisy.


The change will come once people start searching for stuff on Google and they get results which link back to lemmy. For that to happen we need people asking for help/feedback and getting their answers here.
