ARCTIC P12 Pro PST LN Value pack (5pcs)
The ARCTIC P12 Pro PST LN PC fan efficiently removes warm air from inside your computer case and cools internal components. This 120mm PWM fan offers an optimised speed range for quiet operation and stable airflow. This value pack of five allows you to fully equip your case to create balanced pressure. The airflow reaches 83m³/h at a speed of 2000rpm. The device operates at a voltage of 12V and has a starting voltage of 3.3V. Its 25mm deep design is highly efficient in the limited space of a computer case.

Quiet operation
This quiet PC fan is aimed at users who require a silent system. The design, from the LN Silent Enthusiasts series, emphasises a balance between performance and low noise rather than high performance figures. The speed range starts at 450rpm and smoothly increases to a limit of 2000rpm. During operation, it produces just 25dBA of noise while generating a static pressure of 3.5mm H₂O. The modified blade shape improves airflow without creating unwanted aerodynamic noise.
FDB bearing
The FDB fan uses a fluid dynamic bearing with an extended shaft for longer, trouble-free operation. This design approach improves pressure distribution within the bearing and significantly reduces friction between rotating parts. The extended shaft effectively dampens internal vibrations and reduces mechanical noise during rotation. The stable shaft seating prevents unwanted impeller oscillations, even at a full load of 2000rpm. The result is smooth operation that prevents premature wear of mechanical parts.
Balancing
The manufacturing process for these fans involves a robotic measurement and balancing system. Each individual unit undergoes an inspection where a balancing mass is precisely applied to designated spots. This technological process removes minor irregularities in the weight distribution of the impeller. Eliminating imbalance prevents the creation of resonances that could be transferred to the computer case structure. A balanced rotor contributes to quiet operation across the entire supported speed range.
SOTA microcontroller
The integrated SOTA microcontroller actively dampens motor noise and contributes to its smooth rotation. The control chip constantly compensates for load fluctuations and maintains stable speeds even with changing air pressure inside the case. The electronic circuits provide protection against current surges during system start-up. The electronics also protect the fan from damage due to potential reverse polarity when plugging in the connector. This ensures your PC cooling runs safely and without any electrical buzzing.
Synchronised speed control
The PST (PWM Sharing Technology) in the ARCTIC P12 5 pack uses an integrated cable splitter to synchronise multiple units in series. This system lets you connect several fans in a chain and control them using a single PWM signal from the motherboard. This connection method simplifies cable management inside the computer case and saves free connectors. The 400mm power cable includes both a 4-pin PWM connector and the corresponding socket for daisy-chaining.
