ARGUS Inter-Tech L-12025 case fan 120 mm, 1200 RPM, 54 m³/h, fluid bearing, black/blue

ARGUS Inter-Tech L-12025 is a 120 mm axial case fan designed for PC case ventilation, offering up to 1200 RPM and an airflow of 54 m³/h. The fan uses a fluid bearing to reduce operational noise and extend service life. Its two-colour black and blue design is complemented by a spiral LED effect produced by multiple LEDs, providing interior illumination for desktop system enclosures. The fan can be mounted to operate as intake or exhaust and connects via a 3-pin mainboard connector or a 4-pin Molex to the PSU.

Advantages

The fluid bearing reduces friction and noise during operation while improving long-term reliability compared with sleeve bearings. Rubberized vibration absorbers on the corners minimise transfer of vibrations to the case, helping to maintain a quieter system. The fan’s LED spiral effect improves internal case lighting without affecting airflow performance. A choice of mounting orientation and dual connection options (3-pin motherboard or 4-pin Molex) provide compatibility with a wide range of desktop systems.

Suitable for

• PC case intake or exhaust ventilation
• Improving airflow for CPU, GPU and chipset cooling
• Replacing or upgrading existing 120 mm case fans
• Systems where reduced vibration and quieter operation are desired

How to use

Install the ARGUS Inter-Tech L-12025 into a standard 120 mm fan mount in your PC case, aligning the airflow direction marker on the frame with the desired intake or exhaust orientation. Secure the fan using the supplied screws or compatible fan-mounting hardware, using the rubberized vibration absorbers to reduce vibration transmission. Connect the fan to a 3-pin motherboard header for voltage-controlled operation or to a 4-pin Molex connector from the power supply for direct power. Ensure the fan cable is routed clear of moving parts and obstructions before powering the system.

Usage recommendations

For best thermal results, combine the L-12025 with a system airflow plan that balances intake and exhaust fans. Regularly clean the fan blades and grille from dust to maintain airflow and bearing life. If you require precise speed control, use a compatible fan controller or a motherboard header that supports voltage or PWM control where applicable.
