Why my fan sounds weird?
Hello folks.
My fan began sounding weird.
I'm not sure how to describe a sound. I only heard air moving, today it sounds more like an electric motor, like a loud hard drive.
I popped the lower case, fan is a bit dusty, but it does not look clogged or obstructed.
What can it be? Is there any DIY remedies I can try?
Is this a good question?
