The Phanteks Polar ST4 CPU Cooler

The Phanteks Polar ST4 CPU Cooler is an affordable and efficient air-cooling solution designed to enhance entry-level gaming PCs or workstation setups. With its high-performance components and stylish design, it offers an excellent balance between cooling power, noise reduction, and aesthetics. Here’s a breakdown of the features and specifications:

High-Performance Cooling at an Affordable Price

The Phanteks Polar ST4 is engineered to provide exceptional cooling for systems with a TDP (Thermal Design Power) of up to 235W, making it suitable for most mid-range CPUs. It uses four sintered powder copper heat pipes, which make direct contact with the CPU heat spreader to efficiently draw heat away from the CPU and transfer it to the fin stack for dissipation. This ensures your CPU remains cool even under moderate workloads.

Sleek Design

This cooler is specifically designed to ensure RAM compatibility by keeping the cooling fins compact enough not to interfere with your memory modules, even in smaller cases. Its clean and simple design features a silver base with black fins, offering a modern aesthetic that complements any PC build, especially for those who prefer a minimalist style.

Phanteks M25-120 DRGB PWM Fan

At the heart of the cooling solution is the Phanteks M25-120 PWM fan, a 120mm fan that operates between 400 and 2000 RPM. This fan can be controlled based on CPU load to optimize performance and noise levels. It provides a substantial 84.26 CFM of airflow and a static pressure of 2.67mmH2O, ensuring efficient heat dissipation. Despite its performance, it operates at relatively low noise levels (35.7 dBA), making it a quiet cooling solution.

The fan is also equipped with vibrant DRGB (digital RGB) lighting, which adds customizable color effects to your build. The RGB can be controlled using various software solutions, such as ASUS Aura Sync, MSI Mystic Light, ASRock Polychrome Sync, RGB Fusion 2.0, and Razer Chroma, allowing you to sync the lighting with other components for a unified look.

Premium Build Materials

The Polar ST4 utilizes premium materials for durability and efficiency:

• Copper base plate for optimal thermal transfer.
• Aluminum heatsink to provide a lightweight yet effective heat dissipation solution.

Additionally, the cooler comes with Phanteks PH-NDC thermal compound (4.3W/m-K), which effectively closes the gaps between the CPU heat spreader and the cooler base, further improving thermal conductivity.
