They move plenty of air through a 2" heater core at 12V (actually move plenty down to 7 or 8V but are (IMHO) loud (35 or 38 dB at a guess).
Upon disassembly and inspection, they are
not the quiet bladed japanservo fans I was looking for, but a simple forward blade (will follow up with photos - probably uninteresting except that this cage fan pretty much fits where you'd put a 120mm axial fan - two of the three mounting holes line right up with the holes for a 120mm fan).

PS: anybody want 'em?
