DeepCool FK120 120mm PWM Cooling Fan

The DeepCool FK120 delivers precision-engineered cooling performance for PC cases, radiators, and heatsink applications. This 120mm PWM fan combines high airflow capacity with exceptionally quiet operation, making it an ideal choice for system builders who demand both performance and silence.

Precision Engineering for Maximum Airflow

Carefully constructed and tested to enhance static pressure and concentrate airflow for outstanding cooling performance on any mounting application including cooler heat sinks, radiators, and case fan configurations. The narrow frame bezel and wide fan blade provides increased surface area to deliver higher efficiency.

Performance Specifications

Operating at a PWM range up to 1850 RPM, the FK120 achieves 68.99 CFM airflow with 2.19 mmAq air pressure. The 4-pin PWM connector enables dynamic speed control, allowing the fan to automatically adjust between 500-1850 RPM based on system temperature requirements. This adaptive performance delivers optimal cooling when needed while maintaining quiet operation during low-load conditions.

Fluid Dynamic Bearing Technology

The fluid dynamic bearing system provides superior performance and reliable long-term stability. Maxing out at just 28dBA under full load, the FK120 maintains exceptionally quiet noise levels even during intensive cooling tasks. This bearing technology reduces friction and wear, extending operational lifespan while minimizing acoustic output.

Durable Construction

High-quality polybutylene terephthalate (PBT) material is used to ensure increased durability and wear resistance, allowing the fan blades to maintain high tensile strength. Shock-absorbing rubber pads shield the screw mounts to reduce unnecessary vibrations for stable operation. The 120 x 120 x 25mm dimensions and 170g weight provide standard compatibility with most PC cases and radiator mounts.
