I noticed it a few days ago that whenever my laptop is open/on there is a strange, very brief spin-up sound coming from what seems like the left side. It happens at a very regular interval, about every 5 seconds.
I was able to record it, you can here it faintly 3 times here https://imgur.com/a/J37Ekyn
Any help or advice is appreciated! Everything seems to work fine otherwise, its just really annoying.
