I need a decent, yet cheap fan for exhaust purposes. Planning on using one to build a solder fume extractor. Are the RPMs as advertised? How's the reliability of the fans?\ Does more fins mean better air flow?
I was thinking 120mm. Noise isn't an issue. Is CFM more important than RPM? I need it for extracting fumes during soldering jobs.
cfm or cubic feet per minute is more important than rpm as its the amount of air that the fan can move in a given time.must be big solder jobs.lol
