Ventoinha para caixa de computador White Shark Pulsar 12 cm preto

The White Shark Pulsar Computer case Fan 12 cm in black is a 120 mm cooling fan designed for standard PC enclosures. It operates at 12 V and delivers up to 1100 RPM with a maximum airflow of 25 CFM while producing a noise level of approximately 25 dB. The fan uses a hydraulic bearing to provide improved durability and stable performance over time, and its 120 x 120 x 25 mm dimensions make it compatible with most case fan mounts. The simple black finish integrates discreetly into a range of builds, offering a compact cooling solution for everyday desktop systems.

Advantages

The Pulsar fan combines low acoustic output with adequate airflow for case ventilation, reducing ambient noise without compromising ventilation performance. The hydraulic bearing increases lifespan and reduces friction-related wear compared with basic sleeve bearings. Its standard 120 mm form factor and 25 mm thickness ensure wide compatibility with case mounts, fan controllers and filters. Lightweight construction simplifies installation and placement inside the case.

Suitable for

• General system case ventilation to improve internal airflow
• Replacement of worn or noisy 120 mm case fans
• Entry-level and mid-range desktop PCs where quiet operation is preferred
• Supplementary airflow for HDD cages, GPU exhaust areas, or intake vents

How to use

Mount the fan into a compatible 120 mm case fan location using the provided screws or existing case mounting hardware, ensuring the correct airflow direction is oriented for intake or exhaust according to your cooling plan. Connect the fan to a compatible 3- or 4-pin header or to a 12 V power source as required by your system; verify connector type before installation. After powering on the system, monitor fan operation and system temperatures to confirm the fan is functioning and contributing to improved case airflow.

Recommendations

For quieter operation, install the fan in locations with minimal vibration contact and consider using rubber grommets or anti-vibration mounts. Keep intake areas free of dust by using filters and perform periodic cleaning to maintain optimal airflow and prolong bearing life.
