"You are looking for a 40mm 12V brushless DC fan. Asus
motherboard Fan headers are uniformly 12V operation and have
three pins. If all you can find is a two wire fan, the wires go
to +12V (red) and GND (black). The tachometer wire is optional,
and if present allows the fan RPMs to be monitored. Without the
third wire, it will read zero. This Radio Shack fan doesn't
have the three pin female connector on the end, so "some user
assembly required" :-(

The only exception I know of, to the use of 12V fans, is on
video cards. You may find the odd 5V fan on those, with perhaps
a different connector on it. An obvious way to know the
difference, is to check the voltage delivered to the fan header
pins while the system is powered, using a multimeter.
What you don't know, is how many "cubic feet per minute" of air
you want the fan to move. But, at this size of fan, the volume
is tiny in any case.

Coolermaster noise number looks good enough without speed
adjustment.
