How to Control Case Fan Speed
著者: 鈴木 陽菜
Here’s a spicy fact: Dust makes your fans run harder to move the same air. A dusty fan at 80% speed moves less air than a clean fan at 40%. It’s physics, but it’s also annoying.
Clean your fans every three months. Use a toothpick to stop the blades, then blow with compressed air. You’ll instantly lower your noise level by half. It’s like giving your PC a spa day.
Pro move: Set your fan curve to spike to 100% for one second every week. This blasts off loose dust. Your PC will sneeze out the gunk. It’s hilarious and effective.
What About Different Fan Types?
Not all fans are created equal. Some fans have PWM (Pulse Width Modulation) pins. These are four-pin headers. They let you control speed very precisely from 0% to 100%.
Other fans are DC (three-pin). These are simpler. You control them by lowering voltage. They don’t go super slow, and they can make a weird buzzing sound at low speeds. PWM is the king.
Look at your fan cables. If you see four wires, you’re golden. Three wires? You can still control them, but expect less range. It’s like having a sports car with two pedals.
