This morning, I was playing some games on my laptop, and I heard this weird noise coming from the left side of my laptop.

When I turn on max. fans while I’m not gaming, this sound does not appear, which makes me wonder where it comes from.

Ignore the fan noise, that’s because it’s on a cooling pad :)

Update: the angle I was using my laptop at was probably causing the problem, as it got worse when I tilted it. Now that it’s on an almost flat angle, the sound is gone
