Funny how the power consumption doesn't change....
Silent Eagle
1000 Silent Eagle
Rated voltage 12 V (DC)
Power consumption 1.44 W
Fan speed 1000 rpm
Airflow 11.4 CFM
Noise level 8.9 dB(A)
Dimensions (mm) 80 x 80 x 25
Connector universal
Silent Eagle 2000
Rated voltage 12 V (DC)
Power consumption 1.44 W
Fan speed 2000 rpm
Airflow 22.7 CFM
Noise level 17.8 dB(A)
Dimensions (mm) 80 x 80 x 25
Connector universal
1.6 in radius
1000 rpm = 16.67 rps
2*pi*1.6=10 inches
166.7 inches per second
13.9 feet per second, tip velocity
1.6 in radius
2000 rpm = 33.33 rps
2*pi*1.6=10 inches
333.3 inches per second
28.8 feet per second, tip velocity
I agree with Kach (did I say that?) that the velocity is pretty darn low and most likely will not have much effect on the noise.
