how long can last 9v battery on that fan?

It depends on the brand of battery and how often you use it. I used it for maybe 20 minutes once a month and it lasted over a year. Then I put the battery in something else

sorry, make that about 150 RPM

How many RPM does it have? I made one of these and it works fine with 2 AA batteries and it has about 50 RPM.

 I would use a 9v and two AA or AAA's, to get exactly 12v, but it looks like it works fine with 9v. Great job! Really good use of the battery case!

thanks (: actually at first i wanted to do that so it would get all 12 volts, but i thought it looked better with just the 9 volt, and it still works really good.
