Benefits of Upgrading Cooling Fans on Ender 3 S1 Pro

Upgrading the cooling fans on your Ender 3 S1 Pro can have several benefits. Let’s explore them:

  1. Reduced Noise: Replacing the stock fans with quieter alternatives can significantly reduce the noise generated during printing. Quieter fans contribute to a more pleasant working environment and prevent disturbances.

  2. Improved Cooling: Upgraded fans can enhance the cooling efficiency of your printer. Proper cooling is crucial for maintaining consistent print quality, especially during long or complex prints. Better cooling helps prevent overheating and warping of printed layers.

  3. Enhanced Print Quality: Efficient cooling ensures that each layer of filament solidifies properly. This results in cleaner, smoother surfaces and reduces the chances of defects like stringing or layer misalignment.

Now, let’s dive into the specifics:

  • The Ender 3 S1 Pro has four main fans:

    • Part Cooling Fan: This fan cools the printed layers as they are deposited. Upgrading this fan can significantly impact print quality.
    • Hotend Fan: The hotend fan keeps the extruder assembly cool. Replacing it with a quieter fan can improve overall noise levels.
    • Mainboard Fan: The mainboard fan prevents the electronics from overheating. Consider upgrading it for better cooling efficiency.
    • Power Supply Fan: The power supply fan ensures stable operation. Upgrading it can contribute to system reliability.
  • Recommended Fan Upgrades:

    • Noctua NF-A4x10 and Noctua NF-A4x20: These premium-quality, near-quiet fans are excellent choices for part cooling and hotend applications.
    • Noiseblocker Black Silent 40 x 10 mm: Known for reliability and ultra-silent operation.
    • Orion OD4010-24HB: Louder than Noctua or Noiseblocker fans but offers better airflow.
  • Installation Tips:

    • Be cautious when working with the power supply and mainboard.
    • If using 12V fans, consider using a buck converter.
    • Print a suitable duct or shroud for the part cooling fan.

Remember, the right fan choice depends on your priorities—whether you prioritize cooling power or noise reduction. For a balanced upgrade, consider replacing the stock hotend fan with a quieter 40 x 20 mm fan like the Sunon MF40202V2-1000U-A99. It strikes a good balance between airflow and noise reduction.
