Aurora R12, making chirping noise
Good day,
My computer is making a high frequency chirping noise. It does not make this noise all the time but at random times. I'm not sure how to upload an audio recording to this form but I do have a recording of the sound. I have had my computer checked but no damage or failing components were found. Any suggestions?
Thanks, Matthew

As I said, you may not be able to eliminate it. Read the links that I gave you, as they have some tips. But, usually you have to live with it.
A forum member said his Alienware coil whine stopped when he disabled C-state control in BIOS.
You could also disable Turbo Boost, which might make a difference, though you might not want to lose that processor boost. Settings | System | Power & Sleep | Additional power settings | select your plan | Change plan settings | Change advanced power settings | Processor power management | Maximum processor state: set to 99% or lower.
If you set it to anything below 100%, Turbo Boost will not activate.

You don't know whether you have a hard drive or an SSD? Open disk defragmenter (press Windows key and type defrag). It will say whether it is a solid state drive or hard drive.
If it's not the hard drive, it sounds as though your laptop has what is called "coil whine".
Essentially, coil whine is the audible effect of components vibrating, especially when under high load / high power. It can sound like a whine, buzz, hum, scratching, hiss, rattle or vibration. This happens with many components, but often it's not loud enough for us to hear or at a frequency that we don't hear well.
These two pages have more explanation and some tips to reduce the effect:
Unfortunately, you may not be able to eliminate it to your satisfaction. Much depends upon how you use your computer, the acoustic qualities of your room, other ambient noise, etc.
Components that were previously quiet can develop coil whine as they age. It has also been reported that certain software (usually games) that draw a specific power load can cause an inductor to vibrate at a specific frequency that is audible.
I once had a Netgear router whose coil whine was particularly annoying to me. I found that the volume varied among units of the identical model. I tried two or three other units of the same model in the store, and found one that I couldn't hear. Even though they were the same model, same components and power supply, two or three of them were loudly annoying to me, but the last one was inaudible.

More detail would be useful. For example:
If it's not coming from the speakers or a hard drive, I suspect that it is coil whine.

My computer is an alienware aurora r12 and the noise is not coming from the speaker as I can unplug the speakers and headphones and the sound is still there. It can occur under load or when idle. This is a recent thing.

Also here is a link to the sound https://drive.google.com/file/d/1M9btA41hT1nQxt7EJmsQIZhbkTbZ8Noy/view?usp=drivesdk
It is quiet so make sure your sound is high.

I really can't hear anything other than a low background hum.
You didn't answer whether you have a hard drive or a solid state drive.

Almost certainly either a fan or coil whine.

Hi,
I looked in the BIOS settings and could not find C_state control. Do you know where this setting is in alienware bois settings.
Thanks Matthew

It is a solid state. My solid state drive was changed after the noise started. The noise has continued after that.

I think it is a hard drive but I'm not 100% sure. My old hard drive was replaced as it was failing. The noise started before we replaced the hard drive so it was not that. The cpu fan was also replaced as that failed but that did not stop the noise.

I don't know, as I don't have an Alienware laptop to check. It's possible that you don't have it. Maybe it was on more recent models, or a different BIOS version. I don't recall which Alienware model that forum member had.
