I know that - I was planning on "undervolting for quiet" so I figured I'd take a chance with $4 (really $8 for 2 plus $6 shipping)
Does that make this officially the "little-ass blower"?
More seriously - any idea how much (and where) to get some of the non-surplus ones? Or, better yet, impellers using the "silent blower" fanwheel from japan servo (see
this PDF from our "links" area)

The only part that was annoying was getting the impeller
straight and
centered on the motor/hub. I can't tell if they came from Rotron straight and centered or not - they came to me with the impellers pushed so far down they wouldn't rotate at all (maybe AllElectronics gave me the ones from the bottom of the pile).
Given that I already had a plate designed to fit exactly where a 120mm fan went and a shroud also designed for a 120mm fan, using four long bolts was a no-brainer (and cheap). The aluminum sheet was $0.25 at the hardware store and cut fine with scissors (good thing because I
broke my aircraft snips trying to cut a PC case - Mr. Ham-fist himself).
Cathar - I
totally agree. It wouldn't be hard for Rotron to do that. Short of that happening, maybe our friends at coolingworks might look at putting together an "impeller kit"...? Want me to ship a couple of these "little assed blowers" down your way?
