What is the difference between 120mm and 140mm fans?

Size is the main difference. 140mm fans are larger and can push more air at lower speeds, meaning they offer excellent cooling much more quietly than 120mm fans, provided your PC case supports the larger size.

What does PWM mean in PC fans?

PWM (Pulse Width Modulation) technology allows your motherboard to intelligently control the fan speed based on your PC's temperature. The fans spin quietly during light tasks and automatically ramp up during heavy gaming to ensure optimal cooling.
