What are computer fan sizes in inches?

Computer fan sizes are typically measured in millimeters (mm) rather than inches. However, for reference, here are approximate conversions from millimeters to inches for some common fan sizes:

  1. 80mm fan ≈ 3.15 inches
  2. 120mm fan ≈ 4.72 inches
  3. 140mm fan ≈ 5.51 inches
  4. 200mm fan ≈ 7.87 inches

These conversions are approximate, and it’s always a good idea to use the exact millimeter measurements when dealing with computer components. When looking for replacement fans or considering fan upgrades for your desktop case, be sure to check the specifications to ensure compatibility with your case and mounting locations.
