Five black 120 mm PWM fans with Y-cable splitter in box

ARCTIC

ARCTIC P12 Pro PST 5 Pack 120 mm PWM Fan

SKU CH-925C-G51TQ

A 120 mm PWM fan five-pack with 600-3000 RPM speed range, fluid dynamic bearing, and daisy-chain PST connector for synchronised control

  • High static pressure penetrates dense radiators and mesh panels
  • PWM control adjusts speed from 600 to 3000 rpm and stops below 5% duty
  • Fluid dynamic bearing self-lubricates for quiet, long-lasting operation
  • Redesigned blades balance airflow and low noise at low speeds
  • PST daisy-chain connector lets multiple fans run synchronously from one header

Five-pack 120 mm PWM fans

The ARCTIC P12 Pro PST comes as a five-pack of 120 mm PWM fans designed for builders who need multiple coordinated cooling units. Each fan uses a 4-pin PWM connection and includes a Y-cable splitter for daisy-chaining. The fluid dynamic bearing and redesigned rotor blades target quiet, efficient airflow for radiators, perforated panels and mesh structures. The pack suits enthusiasts building custom loops or high-airflow cases.

PWM control limits and daisy-chain capability

Speed is adjustable from 600 to 3000 rpm via the 4-pin PWM header and the fan stops completely below 5 % PWM duty cycle. The integrated SOTA microcontroller reduces motor noise and compensates for speed drops when resistance increases. Protection circuits limit inrush current and guard against reverse-polarity damage. Multiple fans connect in series through the extra PWM connector so a single motherboard header controls the whole chain.

High static pressure for restrictive cooling

The defining specification is high static pressure that lets airflow penetrate dense radiators, narrow perforated panels and mesh fabrics. Minimal manufacturing gaps and automatic balancing maximise pressure efficiency while keeping vibration low. Buyers who need maximum open-air volume flow without resistance should consider alternative fan designs. This pack is built for restricted-path cooling where pressure matters more than raw CFM.

Questions about this item

How do I choose between the single fan and the 5-pack?

The 5-pack includes five identical 120 mm PWM fans plus a Y-cable splitter, letting you populate multiple mounting points and run them from one header.

What does the 3000 RPM top speed mean inside my case?

At full PWM duty the fan spins at 3000 RPM, delivering maximum static pressure for dense radiators or restrictive mesh panels.

How does the 4-pin PWM interface and PST daisy-chain work in practice?

Each fan has a 4-pin PWM connector and an extra PST header, so you can link several fans in series and control them synchronously from a single motherboard header.
