DELOCK 67303 Computer Case Fan 120 mm, 24 V, Ball Bearing, Black

DELOCK 67303 is a 120 mm computer case fan designed to provide parallel airflow for cooling PC enclosures and electronic components. It has a compact 120 x 120 x 25 mm black frame, operates at 24 V and uses a ball bearing for durable and reliable rotation. The fan is intended for chassis ventilation, component cooling and replacing existing airflow units.

Advantages

The fan combines a standard 120 mm form factor with a ball bearing design to offer extended service life and steady performance under continuous operation. Its 24 V rating makes it suitable for systems and devices that require higher-voltage fans, and the black housing allows inconspicuous installation in most builds.

Suitable for

• Cooling computer cases and chassis
• Ventilating electronic enclosures and power supplies
• Replacing or upgrading existing 120 mm fans

When it may not be suitable

This fan is intended for applications that accept a 120 x 120 x 25 mm fan and a 24 V supply. It may not be suitable for systems that require lower-voltage (e.g., 12 V) fans, ultra-quiet low-RPM operation, or specialized bearings such as fluid dynamic bearings if noise and vibration at higher speeds are a concern.

Key specifications

• Fan size: 120 x 120 x 25 mm
• Rated voltage: 24 V DC
• Bearing type: Ball bearing
• Airflow: 1.73 m³/h
• Color: Black

How to use

Install the fan in a compatible 120 mm mounting location in the case or enclosure, ensuring correct airflow direction for intake or exhaust. Connect the fan to a 24 V power source or fan controller compatible with 24 V fans, secure mounting screws to minimize vibration, and verify operation before closing the chassis. Regularly check for dust buildup and clean as needed to maintain airflow and cooling performance.

What to consider before purchase

• Voltage compatibility with your system (requires 24 V)
• Physical fit: 120 x 120 x 25 mm mounting space
• Desired noise level and bearing type (ball bearing characteristics)

Recommendations

Use the fan as part of a balanced airflow setup: position intake and exhaust fans to create smooth parallel airflow across components, and pair with dust filters and regular maintenance to sustain cooling efficiency and service life.
