Question Buzzing noise coming from the case


Jan 2, 2014
Describe your problem. List any error messages and symptoms. Be descriptive.

The PC makes a weird buzzing noise when there's an input such as scrolling or pressing a key on the keyboard. The noise is not too loud, but in an empty and quiet room you can easily hear it. It also buzzes when under load sometimes. Such as running a game or opening an application which I found to be normal. But just when simply scrolling through reddit, it buzzes as I'm scrolling. If I stop scrolling, it stops buzzing.

Here is the noise it makes:

Make sure to listen with headphones because the sound is muffled here and try to ignore the fans spinning noise. Starts around 0:05 then as you can hear me pressing a button on the keyboard, the noise starts. If I release a button, the noise stops.

List anything you've done in attempt to diagnose or fix the problem.

I checked if everything is plugged in correctly.

I tried unplugging my headset, mouse, keyboard, ethernet cable and turning off my monitor.

I checked the temperatures while running Cinebench, everything was normal. ~60°C on CPU scoring 4734, all cores running at ~4GHz.

Post relevant photos of build/parts here.


Provide any additional details you wish below.

Could this be GPU coil whine? The noise also happens when the GPU isn't under heavy load and fans are not turning (low temperatures).

I can only make out the sounds of your keyboard keys. I think what you're referring to is known as coil whine. It can happen to high and low end devices. Now Coil whine can come from any device on your computer, so long as there is a power delivery area or VRM, and can come about when you're taxing the system lightly or heavily.

If you've narrowed down the component that is emitting the noise, you might want to reach out the part's maker and the seller to inform them of the issue in case you're given the green signal to initiate an RMA.
