Stellar Thermal Performance for Demanding Workloads
The AG400’s four copper heat pipes make direct contact with the CPU, rapidly transferring heat away from the processor. This design, combined with the high-efficiency 120mm PWM fan, provides excellent cooling for CPUs with up to 220W TDP. Whether you’re gaming, streaming, or running intensive applications, the AG400 maintains optimal temperatures to prevent thermal throttling.
Compact Design with 100% RAM Clearance
Measuring just 125mm x 92mm x 150mm, the AG400’s compact footprint ensures it won’t interfere with your RAM modules. The slightly offset heat pipe arrangement allows for easy installation even with tall memory modules installed. This makes it perfect for smaller form factor builds where space is at a premium.
Balanced Bidirectional Heat Pipe Technology
DeepCool’s advanced heat pipe technology optimises the internal capillary structure and liquid content to deliver consistent performance regardless of case orientation. This means the AG400 performs equally well in both vertical and horizontal mounting configurations, providing reliable cooling whether your PC stands upright or lies flat.
Simple Installation with Fan Lock Mounting System
The AG400 features DeepCool’s innovative Fan Lock mounting system, which allows you to install the cooler without removing the fan first. This saves time and reduces the risk of damage during installation. The included mounting brackets support both Intel and AMD platforms with a straightforward five-step installation process.
