Antec A400i RGB CPU Air Cooler | 120mm PWM Fan, 4 Copper Heat Pipes, 150W TDP

The Antec A400i RGB CPU Air Cooler is a high-performance processor cooling solution designed to deliver efficient heat dissipation, reliable thermal performance, and attractive neon RGB lighting for gaming PCs, desktop computers, and professional workstations.

Featuring a powerful 120mm PWM RGB LED fan, the Antec A400i operates at speeds ranging from 800 to 1800 RPM, delivering a maximum airflow of 72 CFM and static pressure of 2.1 mmH₂O for effective processor cooling.

The cooler incorporates four 6mm direct-touch copper heat pipes that transfer heat directly from the CPU surface to an aluminum fin heatsink. This advanced design improves heat transfer and helps maintain stable processor temperatures during demanding computing applications.

With a 150W TDP cooling rating, the Antec A400i is suitable for compatible Intel and AMD processors with thermal cooling requirements within the cooler’s rated capacity.

Its integrated automatic neon RGB lighting produces attractive multicolour illumination, enhancing the visual appearance of modern gaming computers without requiring a separate ARGB lighting controller.

The intelligent 4-pin PWM fan connector enables motherboard-controlled fan speed regulation, helping balance cooling performance and operating noise according to CPU temperatures.

Designed for efficient cooling, the fan operates within a manufacturer-specified noise range of 20–36 dB(A), depending on fan speed.

The Antec A400i features a durable aluminum heatsink with four copper heat pipes, supporting effective heat distribution and long-term thermal reliability.

With overall dimensions of 128 × 76 × 155mm, the cooler fits compatible computer cabinets offering at least 155mm CPU cooler clearance.

The cooler supports a wide range of Intel and AMD sockets, including Intel LGA 1700, 1200, 115X, 1366, 2011 and AMD AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2 and FM1.

Its metal mounting system simplifies installation, making it a practical choice for new PC assemblies and compatible desktop upgrades.

Backed by a 1-year manufacturer warranty, the Antec A400i combines powerful cooling capability, stylish neon lighting, broad socket compatibility, and reliable performance.
