We would like to introduce you to BC Robotics biggest fan – har har! These 120x120mm 12V fans are typically found in ATX Computer cases, but they can also be used in a variety of other projects requiring moderate airflow.

The fan spins at ~2200 RPM and can move approximately 80CFM. It is fairly quiet – just 36.5dBA. There are two connectors commonly found in PCs on the end – a 4 pin Molex connector designed to fit inline with older style hard drive connectors and a smaller 3 pin Molex KK 2.54mm that is compatible with our 3 pin Molex Header.

To use the fan, simply connect Red to 12V, Black to Ground. The White wire is a Tach signal – it can be used to monitor the fan rotation or left disconnected if it isn’t needed.
