Computer case fan DeepCool FD12 V2 120 mm Black, 500–2500 RPM, Hydraulic bearing, 4 pcs

DeepCool FD12 V2 120 mm is a pack of four black computer case fans designed to provide focused airflow for desktop and gaming systems. Each fan operates in a speed range from 500 to 2500 RPM, delivering up to 79.89 CFM and a maximum static pressure of 4.15 mmH2O. The fans use hydraulic bearings to reduce noise and extend operational life, and support PWM control for precise speed management and thermal regulation.

Advantages

The FD12 V2 fans combine high maximum rotational speed with a compact 120 x 120 x 25 mm profile, offering a balance of airflow and static pressure suitable for radiators and case ventilation. Hydraulic bearings provide quieter operation compared with standard sleeve bearings and improve long-term reliability. PWM support enables automatic fan speed adjustment based on motherboard or fan controller signals, helping maintain lower system temperatures while minimizing unnecessary noise.

Suitable for

• Case ventilation in desktop PCs and gaming rigs
• Cooling for CPU or GPU radiators in compact 120 mm layouts
• Replacement or upgrade of existing 120 mm case fans
• Environments requiring variable-speed fan control via PWM

How to use

Install the fans in standard 120 mm mounting locations inside the computer case, taking care to align airflow direction according to the case and component layout. Connect the PWM cables to the motherboard or a compatible fan controller to enable automatic speed regulation. Use existing fan headers or adaptors if necessary to match connector types. Ensure fans are mounted securely to reduce vibration and check clearance around radiators, drive bays and other components before completing installation.

Recommendations

For balanced cooling and noise performance, configure the system so front and bottom fans act as intakes while top and rear fans serve as exhaust. Use PWM curves in BIOS or software to set temperature thresholds and minimum speeds; a start point is a minimum speed of ~500 RPM and gradual increase above 40–50°C component temperature. Periodically clean fan blades and filters to maintain airflow and bearing longevity.
