Question Pulsating Humming...Is it my AIO?

[rantk7]

Hello, I built this computer about two months ago. Can you hear the pulsating, humming noise in this video?

When I place my ear close to the fans they seem pretty quite....minus ramping the fans up in the video. This humming noise is always there weather I'm running simulations, browsing or it's sitting idle. I see a lot of videos of strange AIO nosies but I don't think it quite matches what I am experiencing. Anyone have advice? It's driving me crazy. I watch my temps all day and they seem fine after changing a few settings in the PBO.

Welcome to the forums, newcomer!

I would take a sheet of A4 paper, roll it into a cylinder and hold one end of the cylinder to your ear while the other end is used to probe for the source of the humming you mention. Having the side panel off is a good idea to help narrow down the noise.

I noticed 70 Deg C as the highest temps showing up in the video, does it go higher than that when taxed?

BIOS version for your motherboard at this moment of time?

If this were an audio system, I would suspect the power supply. 60 cycle hum is a common sympton caused by ripple from a failing power supply. I couldn't really tell from the video if this might be the cause.
