1. How can I make my PC quieter?

A: Use high-quality PWM fans, create a custom fan curve in BIOS, keep good airflow (so fans don’t need to spin fast), and clean dust regularly.

2. Are bigger fans quieter?

A: Yes. 140mm fans usually move the same amount of air as 120mm fans at lower RPM, which means less noise.
