## Long description

The Lian Li Bora Digital 120 mm is a chassis cooling fan designed to provide reliable airflow for desktop computer cases. Measuring 120×120×27 mm, this compact grey fan operates across a variable speed range of 900–1800 RPM to balance cooling performance and acoustic output. With a maximum airflow of 57.97 CFM and a static pressure rating of 1.46 mmH2O, the fan is suitable for general intake, exhaust and targeted spot cooling applications. The unit uses a Fluid Dynamic Bearing to reduce friction and extend operational life while generating noise between 19.4 and 29 dB depending on rotational speed.
Advantages
The fan delivers a combination of moderate airflow and appreciable static pressure in a standard 120 mm form factor, making it compatible with a wide range of chassis mounting points. Fluid Dynamic Bearing technology reduces wear and supports longer service life with stable rotor operation. Its adjustable speed range allows users to prioritize quiet operation at low RPM or increased cooling capacity at higher RPM. The grey finish provides a neutral appearance that integrates with many build color schemes.
Suitable for
Case intake to bring cool air into the chassis
Case exhaust to remove hot air from the system
Spot cooling for components such as VRMs, storage drives, or GPU areas
Replacement or upgrade of existing 120 mm fans in desktops

How to use
Install the fan in a compatible 120 mm mounting location on the chassis using the supplied screws or mounting hardware. Orient the fan so that airflow direction matches the intended intake or exhaust configuration; most fans indicate airflow direction on the frame. Connect the fan to an appropriate fan header on the motherboard or to a fan controller that supports the operating voltage range. Adjust fan speed through BIOS, motherboard software, or a separate controller to achieve the desired balance between noise and cooling.
Usage recommendations
For quieter operation, run the fan at lower RPM settings during light workloads and increase speed under heavy load or higher ambient temperatures. Ensure unobstructed airflow by maintaining cable management and cleaning dust filters regularly. When replacing an existing fan, check mounting hole alignment and confirm power connector compatibility before operation.
