DC Fans are a form of fans suitable for a wide range of applications, where the power supply is a direct current (DC) voltage. This makes them ideal for use in a range of products, such as computers, servers, automotive, telecommunications, automation or consumer electronics.

The 9S1212P4L011 model is a DC fan specifically designed to be used in hot-running, low-profile servers, where it serves both cooling and noise reduction purposes. This fan has a relatively small frame size of 40.8x 28.9mm and a RoHS compliant and CE marked casing, as well as an integrated speed controller.

It is capable of continuous operation at up to 70,000 × 2 h when used in an environment of up to 55°C, and has an operating voltage of 5 to 12V DC, anti-reverse-connect protection, and a maximum air flow of up to 4.3 m3/min.

In terms of sound pressure levels (dB(A)), this fan is extremely quiet, having noise levels of 29dB(A) at 2000rpm, and a sound pressure level of up to 25dB(A) maximum – which is up to 10dB quieter than similar fans of its size.

The 9S1212P4L011 model is a low resistance fan scavenging the air from side to side, with a ventilation pattern that is focused forward, which makes it ideal for uses such as hard-drive coolers. It has a rotation speed of 2600 to 4000rpm, with a suggested speed of 3000rpm, achieved through its internal fan controller.

As a DC fan, it has some unique features, such as the use of a signal input from the user’s system for enhanced speed control or a new, enhanced motor design which reduces energy loss by up to 45%. It also features extremely low start-up voltage – as low as 1.2V – while still delivering a maximum airflow of 4.3 m3/min.

The 9S1212P4L011 model is designed to be exceptionally reliable and durable, with a minimum bearing lifetime of 70,000 hours, allowing for a service life of nearly 8 years. It also features double insulation protection between windings and frame plates for added safety.

In conclusion, the 9S1212P4L011 DC fan is an excellent choice for cooling and noise reduction in a range of applications, thanks to its small size, efficient motor design, easy-to-use signal input, and long service life.
