As well as a data sheet with airflow figures, you can also find an 
article describing how to estimate what flow/pressure a blower will 
produce. In general, CFM ratings are not a useful guide - you need to 
know if a blower will produce enough pressure. Again in general, any 
blower that will produce enough pressure will produce enough airflow in 
amateur applications. I can't imagine any blower in an amateur station 
cooling a tube so much it affected the emission.
