SEi11 VRM noise

vvvfff · 发表于 2023-04-01 12:36:29

I recently bought SEi11. Overall it's great mini pc but i'm noticed high pitched noise sounds like vrm noise. Noise appears under load and during data transfer to internal 2.5 ssd or external usb drive.

Is there any solution?

I have this problem as well with the same model. I noticed it is related to having a speaker plugged into the audio jack. Unplugging it seems to resolve it.

Speakers are not plugged to my pc. I connected only power, lan, and external ssd enclosure.

Hello,
Could you send a video of that and a picture of SN on the bottom of the machine ?

My SEi11 makes exactly the same sound. It changes frequency as I move my wireless mouse.

Noise appears with any 2.5 internal sata drive i have (samsung 860evo, samsung 840evo, transcend 220s, wd blue hdd) and any usb external flash drive or 2.5 enclosure plugged. Without this devices connected sei11 completley silent. On my desktop pc this deviсes also completley silent.
I bought sei11 last week so there is no dust at all.

Since I didn't get any support here I did some research. The noise is gone away when I powered ssd from my desktop power supply. It turns out that the reason for the noise is a failed beelink's power circuit design.

Very disappointing.
