  1. im not worried about the blades. its just not physically possible to push the same amount CFM's with the same blades spinning the same speed even with different moter.
  2. so are you saying that both of these fans are different? Specifications: Fan Dimension (W / H / D) 120 x 120 x 25 mm Fan Speed 2000 R.P.M. Fan Airflow 69.69 CFM Bearing Type Long life sleeve Fan Life Expectancy 50,000 hours Fan Noise Level (dB-A) 19 dBA Connector 3-pin Voltage 12 V and Specifications Dimension 120 x 120 x 25 mm Voltage 12VDC Current (Ampere) 0.35A Input (Watt) 4.2W? 10% Speed (R.P.M.) 2000 R.P.M. Air Flow (CFM) 90 CFM Air pressure (mmH2O) 2.94 mmH2O Fan Noise Level (dB-A) 19 dB-A Weight 116 g Available Color Blue LED Bearing Type Long Life Sleeve Fan Life Expectancy 50,000 hours if so then how? because they just seem like the same fan with a new moter. ether way they spin at the same rpm's with the same fan blades. and what do they mean bye "ideal" situations.
