Deepcool Gammaxx AG400 ARGB 120mm CPU Air Cooler

The DeepCool AG400 ARGB is a single-tower air cooler designed to deliver strong thermal performance in a clean, compact form factor. Rated for up to 220W of heat dissipation, it uses four direct-touch copper heat pipes that sit directly against the CPU surface to quickly absorb and transfer heat into the aluminum fin stack. Its balanced bidirectional heat pipe technology optimizes the internal liquid flow and capillary structure, allowing efficient heat transfer whether the cooler is mounted vertically or horizontally. This ensures consistent cooling performance across different PC case layouts and workloads, while maintaining low thermal resistance over a wide TDP range.

The cooler also focuses on user convenience and quiet operation. Its 120mm ARGB fan supports PWM control, automatically adjusting speed based on system load—spinning faster for maximum cooling during heavy tasks and slowing down for near-silent performance at idle. The fan lock mounting system allows installation without removing the fan, saving time and simplifying the process. With sturdy mounting brackets compatible with both Intel and AMD platforms, the five-step installation ensures secure contact pressure for optimal heat transfer. The slightly offset heat pipe design improves RAM clearance and makes installation easier, even in tighter builds.

Key Feature

Efficient Single-Tower Cooling Design

The Deepcool Gammaxx AG400 ARGB features a compact single-tower heatsink designed to deliver strong cooling performance without occupying excessive space inside the cabinet. Its streamlined aluminum fin stack maximizes surface area for heat dissipation while maintaining compatibility with most mid-tower and compact PC cases.

Direct-Touch Heat Pipe Technology

Equipped with four copper heat pipes that make direct contact with the CPU surface, the cooler rapidly transfers heat away from the processor. This direct contact design improves thermal conductivity and allows efficient heat distribution across the fin stack, helping maintain stable temperatures during demanding workloads.

Balanced Bidirectional Heat Pipe Efficiency

The optimized internal capillary structure and precise liquid filling allow the heat pipes to function efficiently in both vertical and horizontal orientations. This ensures consistent cooling performance regardless of case layout, reduces thermal resistance, and supports effective heat dissipation across a wide TDP range.

High-Performance 120mm ARGB PWM Fan

The included 120mm fan delivers high airflow while maintaining low noise levels. PWM control enables automatic speed adjustment based on system load, providing strong cooling during heavy usage and quiet operation during idle periods. The integrated ARGB lighting adds customizable visual appeal that can be synchronized with compatible motherboard lighting software.

Simplified Installation & Secure Mounting

A fan-lock mounting system allows installation without removing the fan, making setup faster and more convenient. The included mounting hardware supports both Intel and AMD platforms and uses a secure bracket design to ensure firm contact pressure for optimal heat transfer and long-term reliability.

RAM Clearance & User-Friendly Design

The offset heat pipe layout improves compatibility with tall RAM modules and tight motherboard layouts. Its balanced structure, durable build quality, and straightforward five-step installation process make it a reliable choice for both new builders and experienced PC enthusiasts.
