Why can a laptop rustle?

Question

Iron

I bought a laptop the other day. Everything seems to be in order, the cooler is not particularly noisy, but the rustling spoils everything, as if someone is walking far in the snow. Very annoying. You have to wear headphones. It seems to be working fine.
Lenovo g500, if anything. Came with pre-installed Windows 8. Utilities from the vendor so far left. Skype, chrome and system write to the disk in the resource monitor. Reads mostly msmpeng.
Is this normal? How to reduce noise? Googled winaam, but it doesn't work.

Answer 1

The disk rustles. Ordinary disks chirp and rustle, the higher the speed, the more intense the noise. On my computer, this is audible from a distance of 30cm, it became especially noticeable after installing quiet fans. If this is very annoying, you can listen to analogues in the store and change it.

Answer 2

Get yourself an SSD, there is nothing to rustle :)
