/\ The stock Heath fan has an abundance of airflow - provided the 
bearings are oiled occasionally.  The stock fan has so much airflow that 
a 75-ohm resistor can be placed in series with the fan motor to slow it 
down for non-RTTY operation.  

>Is it much noisier than the stock fan?
/\   Users report more noise.
