Dynatron A24 Aluminum Stacked Fin CPU Cooler Socket AM4 - 2U Server

In this review the Dynatron A24 is evaluated as a compact server-focused cooler for AMD Socket AM4 systems. The bottom line: it is best for small form factor or 2U server builds that need reliable, directed cooling without high clearance, and its greatest strength is consistent thermal performance thanks to the aluminum stacked fin design with heat pipes. The reviewer found it keeps midrange Ryzen chips notably cool in constrained chassis, while the 4-pin PWM fan gives automatic control to balance temperature and RPM.

Key Features

• Socket AM4 Support: Designed specifically to support AMD Socket AM4 processors so fitment and contact are straightforward for Ryzen builds in compatible chassis.
• Aluminum Stacked Fin with Heat Pipes: The stacked fin array with heat pipes moves heat away from the CPU quickly, providing sustained cooling under server loads.
• 4-pin PWM Controlled Fan: PWM control allows the fan to ramp with CPU temperature for automatic management of cooling and power draw in a rack or mini ITX case.
• Supports up to 95 W TDP: Rated for processors up to 95 watts TDP, making it suitable for many mainstream and efficiency-focused Ryzen CPUs used in low-profile servers.
• 2U Server Compatibility: The low-profile design is recommended for 2U server and similar compact systems where vertical clearance is limited.

Who It's For

The Dynatron A24 is aimed at system builders assembling a compact 2U server, mini ITX workstation, or other low-profile AMD Socket AM4 systems that need dependable cooling without tall tower heatsinks. It is especially relevant for those who value thermal performance in confined vertical space and want automatic fan speed control with PWM.

Users who prioritize the absolute quietest operation or who need cooling well above 95 W TDP should look elsewhere; larger tower coolers or active server chassis solutions will better suit very high power CPUs or noise-sensitive desktop environments.

Pros & Cons

Pros

• Excellent cooling capacity for its size, keeping Ryzen chips notably cool under sustained load.
• Compact 2U-friendly profile fits low-clearance server and mini ITX cases where tall coolers cannot be used.
• Automatic PWM fan control lets the fan adjust speed based on temperature for hands-off operation.

Cons

• Fan can be somewhat loud at higher RPMs, so acoustic-sensitive users may find it intrusive.
• Some users report mixed experiences with installation, so care and patience are needed during mounting.

Specifications

Our Verdict

The Dynatron A24 is a practical, value-oriented cooler for low-profile AMD Socket AM4 systems and 2U servers. It offers legitimately strong thermal performance for CPUs within its 95 W TDP rating and benefits from PWM fan control, making it a smart choice when space is limited. Buyers who need ultra-quiet operation or higher TDP headroom should consider larger alternatives.

Frequently Asked Questions

Will this fit a 2U server?
Yes, it is recommended for 2U server installations and other low-clearance systems.

Does the fan support automatic speed control?
Yes, the fan uses a 4-pin PWM connector for automatic speed adjustment with motherboard control.

Is it quiet in normal operation?
It performs well at moderate speeds, but the fan can become noticeably loud under higher loads.
