## Summary description

ANTEC Tranquil 140 is a 140 mm computer case fan designed for chassis and cooling systems. It features a 140 mm diameter, Fluid Dynamic Bearing (FDB), and operates from 7 to 13.8 V. Air pressure ranges from 0.11 to 1.79 mmH2O, making it suitable for general case ventilation, radiator or intake/exhaust configurations where balanced airflow and reliability are required.

## Long description

ANTEC Tranquil 140 is a 140 mm computer case fan engineered for chassis ventilation, radiator use and intake or exhaust configurations. The fan uses a Fluid Dynamic Bearing (FDB) for reduced friction and extended service life, operates across a 7–13.8 V range and delivers balanced airflow with measured air pressure between 0.11 and 1.79 mmH2O. The black finish and compact 140 mm form factor make it compatible with many standard PC cases and cooling setups where quiet, dependable operation is needed.
Advantages
The Tranquil 140 combines a dedicated blade and frame geometry to produce effective airflow while keeping acoustic output low. Fluid Dynamic Bearing technology minimizes shaft-to-bearing friction, increasing longevity and reducing operational noise. Minimal clearance between the blade tips and frame improves efficiency, and eight vibration-absorbing pads at the mounting points reduce resonance transmitted to the case.
Suitable for
 Case ventilation to maintain internal airflow and component temperatures
 Mounting on radiators for liquid cooling systems requiring a 140 mm fan
 Front or rear intake/exhaust positions in ATX, micro-ATX and Mini-ITX chassis that accept 140 mm fans
 System builds where a balance of airflow and low noise is required
Key specifications
 Fan diameter: 140 mm
 Operating voltage range: 7–13.8 V
 Bearing type: Fluid Dynamic Bearing (FDB)
 Air pressure range: 0.11–1.79 mmH2O
 Colour: Black
 Mounting: standard 140 mm mounting pattern
How to use
Install the Tranquil 140 in the chosen 140 mm fan position of the case or on a compatible 140 mm radiator using the provided screws or mounting hardware. Ensure the airflow direction marker on the frame is oriented according to desired intake or exhaust flow. Connect the fan to an appropriate fan header or controller that supports the fan's voltage range, and verify cable routing does not interfere with other components. Start the system and confirm the fan spins smoothly without abnormal vibration or noise.
Usage recommendations
For quieter operation, run the fan through a motherboard fan curve or PWM-capable controller (if available) and avoid maximum sustained voltage unless higher airflow or static pressure is required. Regularly check for dust buildup on blades and bearings and clean as needed to maintain performance and service life.
