We aren't interested in power, we're interested in moving a volume of air.
They are very fast, high rpm. Trade off rpm with suitable gearing. You may
need two or more (which is why small may be better).
I've never used them myself except for nervous network sorts of stuff. It
was meant as a suggestion.
If they don't work you've still got a nifty little toy car to drive around
;)
