no PWM / 74,3 m³/h / 8,6 dB(A) / ULN

High quality fan, extremely low noise(8,6 dB(A)), and very long MTTF. This fan has been selected for its extremely low noise level. The airflow is of course slightly less because of that, but you get a extremely low noise fan in return.

If you want a really good fan with a high quality this is the fan to choose. How much does it cost if a(cheaper) fan dies during the lifespan of the server? Or if your disks die because they overheat because of chasis fan problems?

Most server cases are provided with standard fans. You now have the option to proactive replace your case fans with these. Also if  you are replacing the fans with silent fans, these fans you need.

Please note this fan has no PWM and is 3-pins.

The highlights are:

Size 120x120x25 mm
Mounting hole  space 105x105 mm
Connector & pin configuration 3-pin no PWM
Noise 8,6 dB(A)
Airflow 74,3 m³/h
