Noctua fans provide a great combination of airflow, quality, and low noise operation - but are fairly expensive, as fans go. They also have a rather unique color scheme, making them easy to spot in system builds.
This particular model is a 120mm size, commonly used as case fans and CPU coolers, with a PWM type power connection. That lets supporting motherboards control the fan speed, either at a fixed rpm set in the BIOS or adjustable based on temperature.

Aaron Bacon (Production Technician) Says:
I use Noctua fans in all my personal computers. They are excellent at cooling and incredibly quiet. I've always been happy with the results.
