Highlight Features

New P14 Pro A-RGB Fans

• High-performance design with optimized blade geometry

• 400–2500 RPM for precise control from silent idle to full-load cooling

• 5.2 mmH₂O static pressure and 110 CFM airflow for extreme efficiency

• Fluid Dynamic Bearing ensures longevity and quiet operation

Integrated VRM Fan

A PWM-controlled fan built atop the pump delivers direct airflow to motherboard voltage regulators — keeping temperatures low and stability high, even during overclocking.

Offset Mounting for Intel & AMD

The cold plate is strategically offset to align with the CPU’s hottest zones, ensuring superior heat transfer for both AMD chiplet and Intel hybrid designs.

Intel Contact Frame

An optimized mounting frame reduces CPU bending (ILM issue), enhancing contact pressure uniformity, thermal transfer, and CPU longevity.

Integrated Cable Management

All fan and lighting cables are routed inside the sleeved tubing, providing a clean, minimalist aesthetic and making installation quick and effortless.

Premium 38mm Radiator

The extra-thick aluminium radiator provides a larger liquid capacity than traditional 27mm models, enhancing heat dissipation and stabilizing performance during temperature spikes.

Reinforced Tubing

Durable EPDM rubber tubes with braided sheathing ensure long-lasting flexibility, resistance to wear, and a sleek look.

Plug-and-Play Installation

Pre-mounted fans, pre-wired connections, and an easy mounting system — backed by ARCTIC’s animated online guide — make setup fast and frustration-free.

MX-6 Thermal Paste Included

Pre-applied, high-performance MX-6 thermal compound ensures perfect heat transfer — no extra steps needed.
