DeepCool GAMMAXX AG400 BK ARGB CPU Air Cooler - High Airflow Black

In this review of the DeepCool GAMMAXX AG400 BK ARGB, the bottom line is clear: this is a compact, all-black CPU air cooler aimed at gamers and system builders who want strong cooling performance with ARGB style in a midtower-friendly package. The reviewer found the combination of four 6mm direct-contact heat pipes and a high-speed 120mm PWM fan delivers effective cooling up to the claimed 220W TDP while keeping noise under control, making it a practical upgrade for Intel LGA 1700 and AMD AM5 systems where clearance and aesthetics matter.

Key Features

• All-black ARGB design: The chessboard-style black heatsink and ARGB fan provide a cohesive, high-contrast look for black-themed builds without bright plastic trim.
• 220W TDP cooling: Four 6mm direct-contact copper heat pipes maximize heat transfer to handle high single-socket CPU loads for gaming and productivity.
• 120mm PWM fan: The included fan spins up to 2000RPM and moves up to 75.89CFM for strong airflow while keeping audible noise below about 31.6dB(A) at full speed.
• Wide socket support: Mounting hardware supports modern sockets including Intel LGA 1700/1200/115x and AMD AM5/AM4 for broad compatibility.
• RAM clearance: The cooler is designed for full RAM clearance on most motherboards, and the fan can be adjusted if taller memory modules interfere.
• 150mm height: With a 150mm profile it fits most ATX and mATX midtower cases, but checking case cooler clearance before purchase is recommended.

Who It's For

The GAMMAXX AG400 BK ARGB suits gamers and enthusiasts building a black-themed PC who want a visually cohesive cooler that still performs. It is a good pick for users upgrading from stock coolers who need improved thermal headroom for sustained gaming or moderate overclocking while keeping a compact footprint.

Those who should look elsewhere include users with very tall RAM modules that exceed adjusted fan clearance or builders of small form factor cases with less than 150mm of cooler height. Also, extreme overclockers chasing the lowest core temperatures on high-end HEDT CPUs may prefer larger tower coolers or liquid solutions.

Pros & Cons

Pros

• Strong heat transfer from four 6mm direct-contact copper heat pipes for reliable 220W TDP cooling.
• High airflow 120mm PWM fan (2000RPM, 75.89CFM) that balances cooling and noise effectively.
• Attractive all-black heatsink and ARGB fan that fit black or stealth builds without clashing visuals.
• Broad socket compatibility and adjustable fan position for RAM clearance flexibility.

Cons

• 150mm height requires checking case clearance; not suitable for very compact SFF cases.
• ARGB requires a 5V 3-pin header to use lighting effects; systems without that header will not show synchronized lighting.

Frequently Asked Questions

Will this cooler fit my case?
Check your case CPU cooler height limit; the AG400 BK ARGB is 150mm tall so it fits most midtower and mATX cases but not very compact SFF cases.

Does the lighting require a special header?
The ARGB lighting uses a 5V 3-pin sync header; a compatible motherboard header or controller is required to synchronize lighting effects.

Will it block my RAM slots?
The design provides full RAM clearance in most builds and the fan can be unlatched and moved higher to clear tall memory modules if needed.
