DeepCool GAMMAXX AG400 WH ARGB White CPU Cooler - Quiet 220W Cooling

In this review the DeepCool GAMMAXX AG400 WH ARGB is evaluated as a compact all-white CPU cooler aimed at builders who want a minimalist white theme without sacrificing performance. The single biggest reason to consider it is the combination of a 220W TDP-capable direct-contact heatpipe array and a high-speed 120mm PWM fan that manages strong airflow while staying below 32dB at full speed, making it a practical choice for mid-size towers and RGB-focused builds.

Key Features

• All-white design: The all-white heatsink and fan let builders create a clean White Castle or minimalistic style build that keeps the interior visually consistent.
• 220W TDP cooling: Four 6mm direct-contact copper heatpipes and a large fin stack combine to handle up to 220W TDP for sustained gaming and productivity loads.
• 120mm PWM fan: A high-speed 2000RPM FDB fan supplies up to 75.89 CFM of airflow while maintaining noise under 31.6 dB(A) for a balance of performance and quiet operation.
• ARGB sync support: The 5V-3Pin ARGB fan connects to ASUS Aura, Razer, Gigabyte Fusion, MSI Mystic Light and ASRock Polychrome for motherboard-synced lighting control.
• RAM compatibility: Offset heatpipe layout and a slimmer heatsink depth provide full RAM clearance, including taller heat spreaders across all slots.

Who It's For

The GAMMAXX AG400 WH ARGB suits PC builders who want a compact tower cooler with a clean white aesthetic and controllable ARGB for a cohesive look. It is particularly fitting for mid-range gaming systems and compact ATX or mATX cases where clearance and styling matter.

Those who need extreme overclocking headroom or prefer liquid cooling for high-end multi-core CPUs should look elsewhere; similarly, builders who cannot use 150mm height coolers due to very small cases will need a lower-profile option.

Pros & Cons

Pros

• Strong cooling capacity from four 6mm direct-contact heatpipes delivers reliable thermal performance under load.
• ARGB 5V-3Pin fan integrates with major motherboard lighting ecosystems for synchronized effects.
• High airflow 120mm PWM fan keeps noise under comfortable levels even at maximum speed.
• Offset heatpipe design ensures 100% RAM clearance for tall modules and unobstructed access.

Cons

• With a 150mm height, it is not suitable for very small cases or some low-profile builds.
• ARGB requires a 5V-3Pin header on the motherboard for full synchronization; otherwise lighting control is limited.

Our Verdict

The DeepCool GAMMAXX AG400 WH ARGB is a strong value for builders wanting a cohesive white theme with effective cooling and quiet operation. It handles mainstream to moderately demanding processors well, offers full RAM clearance, and adds flexible ARGB for style; buyers with strict case height limits or extreme overclocking needs should compare low-profile or liquid solutions instead.

Frequently Asked Questions

Will this fit tall RAM modules?
Yes. The offset heatpipe and heatsink depth are designed to provide 100% RAM clearance for tall modules.

Does the ARGB work with common motherboard software?
Yes. The 5V-3Pin ARGB fan supports ASUS Aura, Razer Chroma, Gigabyte Fusion, MSI Mystic Light and ASRock Polychrome for synchronized lighting.

How loud is the fan at full speed?
The included 120mm fan produces under 31.6 dB(A) at full speed, making it relatively quiet for its airflow class.
