Premium Build Material
The Phanteks Polar ST4 CPU Cooler is engineered to provide excellent cooling whilst still being at an accessible price point. Each component has been carefully selected and constructed to boost performance and efficiency, resulting in a cooler perfect for entry-level systems. It can effectively manage a TDP of up to 235W.

This cooler features four sintered powder copper heat pipes, which have direct contact with the CPU heat spreader. As such, heat is more efficiently drawn away from your vital components and fed into the fin stack to be dissipated. What’s more, the Phanteks Polar ST4 has been specifically designed so it won’t interfere with your RAM modules.

Optimising heat transfer, the Phanteks Polar ST4 comes with the Phanteks PH-NDC thermal compound, a 4.3W/m-k high-performance paste. This will effectively close any gaps between the CPU heat spreader and the socket.

M25-120 PWM DRGB Fan
A Phanteks M25-120 fan is mounted onto the fin stack. This 120mm PWM fan has a hydraulic bearing and operates between 400 and 2000 RPM, which can be precisely controlled to suit a range of CPU loads and thermal needs. It can produce 84.26CFM airflow at a static pressure of 2.67mmH2O. All whilst remaining at noise levels of 35.7 dBA. Enjoy the outstanding performance with whisper-quiet operations.

What’s more, the M25-120 is equipped with vibrant DRGB lighting, adding a splash of colour to the Phanteks Polar ST4. Using the included cables, you can connect the fan directly to your motherboard and control it through several RGB software. This includes ASUS Aura Sync, RGB Fusion 2.0, MSI Mystic Light, ASRock Polychrome Sync, and Razer Chroma.
