## Long description

PHANTEKS Polar ST4 PH-TC12ST4\_DBK01 is a 120mm CPU cooler that combines a compact tower heatsink with a single 120mm fan featuring addressable DRGB lighting and PWM speed control. The cooler is designed for desktop processors and provides active air cooling suited to standard desktop builds and space-constrained systems. Its layout and fan control enable temperature-responsive operation while the DRGB lighting adds customizable illumination compatible with addressable RGB headers.
Advantages
The Polar ST4 offers a compact footprint that fits many mid-tower and mini-ITX cases while maintaining effective heat dissipation for mainstream CPUs. PWM fan control allows the fan to adjust speed according to CPU temperature, reducing noise during light loads and increasing airflow under heavier loads. Addressable DRGB lighting provides synchronized color effects when connected to compatible motherboard headers or controllers. The cooler's design supports straightforward installation and reliable airflow across the heatsink fins.
Suitable for
 Mainstream desktop processors in standard and compact PC builds
 Systems where a compact CPU cooler is needed to avoid RAM or chassis clearance issues
 PC builds that include addressable RGB lighting and require synchronized illumination
 Users who prefer automatic fan speed regulation through PWM for balanced noise and cooling
Key specifications
 Fan size: 120 mm
 Lighting type: Addressable DRGB (addressable RGB)
 Fan control: PWM (Pulse Width Modulation) compatible
 Cooling type: Active air cooling with tower-style heatsink and single fan
 Compatibility: Designed for desktop processor sockets commonly used in mainstream systems (verify specific socket support with motherboard)
How to use
Install the PHANTEKS Polar ST4 on a compatible CPU socket following the included mounting instructions. Attach the 120mm fan to the heatsink using the provided clips or screws, and connect the fan's PWM cable to the motherboard fan header for automatic speed control. Connect the DRGB lighting cable to an addressable RGB header or controller to enable lighting effects; ensure the motherboard or controller software is configured to recognize addressable DRGB devices. After installation, monitor CPU temperatures and fan behavior in BIOS or system software to confirm proper operation.
Usage recommendations
For optimal performance, ensure adequate case airflow by using intake and exhaust fans, place the cooler to avoid obstruction by tall memory modules, and configure PWM fan curves in BIOS or motherboard software to balance cooling and noise according to workload.
