DELOCK 67338 Computer Case Fan 35×35×10 mm 3.5 cm 12 V Hydrodynamic Bearing Black

DELOCK 67338 is a compact 3.5 cm (35×35×10 mm) DC axial fan designed to cool small enclosures and electronic components. It runs on 12 V and provides steady parallel airflow for ventilation in PCs, NAS units, routers and other confined spaces where continuous air movement is required.

Advantages

The fan uses a hydrodynamic bearing to reduce operational noise and extend service life while maintaining reliable airflow. Its small footprint and black finish make it easy to integrate into tight spaces and a variety of device interiors without drawing attention.

Suitable for

• Cooling compact computer cases and mini-ITX systems
• Ventilation in NAS enclosures and network equipment
• Cooling routers, switches and small electronic housings
• Supplementary airflow for small power supplies or control units

When it may not be suitable

Due to its small size and modest airflow, this fan is not intended for cooling large PC cases, radiators or high-heat components that require high-volume air movement. It also requires a 12 V supply and is not suitable where only different voltage sources are available.

Key specifications

• Dimensions: 35 × 35 × 10 mm
• Impeller diameter: 35 mm (3.5 cm)
• Rated voltage: 12 V DC
• Airflow: 4.2 m³/h
• Bearing type: hydrodynamic bearing
• Colour: black

How to use

Install the fan in the desired orientation to create parallel airflow through the enclosure, securing it with appropriate screws or mounting hardware. Connect the fan to a stable 12 V DC power source following the device wiring conventions; ensure correct polarity. Keep intake and exhaust paths clear of obstructions and verify that the fan has sufficient clearance around the frame for free rotation.

What to consider before purchase

• Confirm available space for a 35×35×10 mm fan inside your device
• Ensure a compatible 12 V power source and connector type
• Check required airflow (4.2 m³/h) is adequate for your cooling needs
• Verify mounting hole spacing and clearance in your enclosure

Recommendations

For quiet, continuous ventilation in confined spaces, position the fan to establish a clear intake or exhaust path and combine with passive vents if possible; periodic cleaning will help maintain airflow and prolong bearing life.
