Enhance the performance of your computer with the be quiet! Silent Wings 3 12V 1600RPM 140mm PWM High-Speed Case Fan in Black. This fan, by the renowned brand 'be quiet!', is designed to provide a smooth and noiseless operation, ensuring both high performance and peace of mind.

The fan comes with 3 conductor power cables and is compatible with a voltage of 12 V. The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours and greatly reduced operating noise (28 dbA). The 1600RPM speed ensures maximum airflow volume of 77 CFM, keeping your computer cool even during intense usage. The be quiet! Silent Wings 3 fan is perfect for individuals who demand high performance from their computers without compromising on silence.

I used it to provide increased airflow to the electrical cupboard on our boat, so I have changed the connectors to car/boat 12v spade terminals. I only used the +ve and -ve wires, so I reduced the length of the third wire, but it’s still there (see pics). It works fine, and can easily be changed to any connector you want.

The fan is fully assembled and comes with the accessories (see pics). It is in very good condition, and I’m only selling it as I have bought an even more powerful fan to maximise the airflow. I will be shipping the SIW3 fan in the box for the new fan for protection.
