## Long description

The Fan Mars Gaming MFSI4KIT 12 cm Black Hydraulic Bearing is a 120 mm case fan engineered to provide stable airflow and reduced noise for desktop systems. Designed by TACENS under the Mars Gaming line, this black fan uses a hydraulic bearing to lower mechanical friction and extend operational life while delivering a maximum air pressure of 2.03 mmH2O. Its compact 120 mm diameter and neutral black finish make it suitable for a wide range of PC enclosures and cooling configurations.
Advantages
The hydraulic bearing offers quieter operation compared with sleeve bearings and improved longevity under continuous use. The 120 mm form factor balances airflow and noise, providing effective heat dissipation without requiring excessive power. A maximum air pressure of 2.03 mmH2O helps the fan maintain airflow through restrictive areas such as dust filters or dense drive cages. The black color and standard mounting dimensions ensure compatibility with most chassis and fan brackets.
Suitable for
Case ventilation and exhaust in mid-tower and mini-tower PC enclosures
Replacement or upgrade of existing 120 mm chassis fans
Supplementary airflow for GPU or VRM area when positioned appropriately
Systems where quieter operation and consistent airflow are desired
Key specifications
Fan diameter: 120 mm
Bearing type: Hydraulic bearing (for reduced noise and longer life)
Maximum air pressure: 2.03 mmH2O
Product colour: Black
How to use
Install the fan in a standard 120 mm mounting location inside the computer case, aligning the mounting holes with the chassis or fan bracket. Connect the fan to the appropriate motherboard header or fan controller, observing correct connector type and voltage. Orient the fan to achieve the desired airflow direction—intake or exhaust—usually indicated by arrows on the fan frame. Secure the fan with screws or vibration-damping mounts and verify cable routing to avoid contact with moving blades.
Usage recommendations
For optimal performance pair the fan with a balanced airflow configuration: use intake fans at the front or bottom and exhaust fans at the rear or top. Regularly clean dust filters and fan blades to maintain airflow and cooling efficiency. If low noise is a priority, connect the fan to a PWM-capable header or a fan controller to adjust speed according to system temperature.
