Hello everyone,

I just bought a brand new ZenBook 14 and it had some slight coil whine issue. It wasn't really audible when I first got it but a week later it is literally become like someone is scratching the blackboard.

As far as I'm concerned the noise is coming from the CPU area- probably the VRMs causing it- but strange enough though, the coil whine noise is completely gone when the CPU utilization is %100.

I have contacted to the ASUS support in Turkey and they told me nothing can be done because this doesn't effect the performance of my computer but this is situation is so frustrating and makes me question the quality of ASUS products overall.

I'm open to any help and opinion so please share them with me.

Thank you all.
