How Do I Turn On My Windows Fan?

Published in CPU Fan Control 3 mins read

The question "How do I turn on my windows fan?" is unclear. It could refer to several different types of "fans". Based on the available reference, it's likely that the user is asking about controlling the CPU fan inside their computer, not an external fan connected to a window. Here's how to manage your CPU fan:

Controlling your CPU Fan Through the BIOS

The primary way to manage the speed of your CPU fan is through your computer's BIOS settings. Here's how to access and adjust them:

  1. Enter the BIOS: Restart your computer. As it boots up, look for a prompt that tells you which key to press to enter the BIOS setup. Common keys include:

    • Delete
    • F2
    • F10
    • F12
    • Esc

    The specific key may vary depending on your motherboard manufacturer.

  2. Navigate to the CPU Fan Settings: Once in the BIOS, use your keyboard's arrow keys to navigate through the menus. Look for sections related to:

    • CPU Fan
    • Hardware Monitor
    • Power
    • Fan Control

    The exact naming may differ.

  3. Adjust Fan Settings: Within the appropriate section, you should find settings that allow you to adjust your fan. Common options include:

    Setting Description
    Fan Type Set to either DC (Direct Current) or PWM (Pulse Width Modulation) depending on your fan's type.
    Fan Mode This controls the fan speed. Options may include:
    * Automatic: The fan speed is adjusted automatically based on CPU temperature.
    * Manual: You can set a fixed speed.
    * Custom: You can often create a fan curve, controlling speed at different temperatures.
    Fan Speed If manually controlled, you can set the speed of the fan.

    According to our reference, you should select the fan type (DC or PWM) and mode.

Key Considerations

  • Fan Noise: Manually setting the fan to a high speed may result in increased noise.
  • Temperature: Be cautious when setting fan speeds too low, as it may lead to overheating. Automatic control is usually the safest and most efficient option.
  • BIOS Variation: BIOS interfaces differ between manufacturers, but the main options for CPU fan control are generally similar.
  • System Compatibility: Before making changes to your BIOS settings, consult your computer's manual to avoid misconfiguration.
