Verification Study Results of Uneven Cooling Fan Weight Balance Distribution
  • Analysis Results
    • The left-side A–B area shows values approximately 14–17 g lower than the average.
    • The weight in the A–B area needs to be increased.
    • Adding weight to the blade area affects runout values; therefore, thickness adjustment is required in the rim area.
