Voltage-controlled, can run between 5-12V. Fairly quiet especially for a 40x28mm fan. There is a small sheet metal bracket attached which you may need to remove (I will not be removing these for you). 300k hour MTBF, all brand-new in bulk packaging. Long story short, I work for a system integrator and my boss gave me a case of these things because we EOL'd all chassis they're used in.
$3/ea + shipping. willing to negotiate if you're buying in volume. I have hundreds.
