Frequently Asked Questions

Is a rattling CPU fan bad?
A rattling CPU fan is not a good sign. If it is hitting something, it could be running slower than it should and may fail sooner rather than later.
Why does my PC sound like it’s rattling?
Your PC sounds like it’s rattling because the fans or hard disk may be causing excess noise. Fans are responsible for cooling the processor, motherboard, and graphics card, so if they are loose or not powerful enough, they can create rattling sounds.
