I finally found the web site of the original part:

http://www.globefan.com/12025.htm

It's speed controlled by voltage: 6-13.8V.

0.52A is the maximum current draw at 13.8V.

Maximum speed is 2800rpm, ~95CFM.

I want to find an equivalent part that is quieter and good quality.

It's not that this is such a bad fan, but sleeve bearings seem to make noise
when mounted flat, airflow upward.  Not sure why.  It's also possible I got a
bad fan.

Cooler Master will not respond to my queries about this, and I don't want to
be without this computer for an RMA which might not fix the problem anyway.

I assume the power supply uses voltage to vary fan speeds, so as long as the
fan can handle the 6-13.8V range of the current part, I suppose amp rating
doesn't matter as long the new fan doesn't draw more than the current part.

The problem is wading through all the fans I don't want... 

LED fans, cold cathod fans, colored fans, fans with bling... after what I've
seen in the last couple of days, I'm expecting to see flavored fans any
minute now.  I'm actually shocked that I've not found scented fans yet.

I've yet to find a seller that has accurate and complete listings, so I
mostly have to search manually, one fan at a time.
