Dynatron A42 copper skived fin side blower CPU cooler for AMD AM4/AM5

Dynatron

Dynatron A42 Copper Skived Fin Side Blower AMD AM4/AM5 CPU Cooler

SKU CH-CZNB-YEQEV

Copper skived-fin heatsink with vapor-chamber base and 80 mm PWM side-blower fan dissipates up to 95 W for AM4/AM5 Ryzen CPUs in 1U servers

  • Supports AMD Ryzen AM4/AM5 sockets for broad compatibility
  • Handles up to 95W TDP for reliable thermal performance
  • Copper heatsink with vapor chamber base transfers heat efficiently
  • 80x80x13 mm PWM blower fan spins at 8600 RPM
  • Delivers 26.25 CFM airflow for effective 1U server cooling

AMD AM4/AM5 Socket Compatibility

The Dynatron A42 is a copper air cooler built for AMD AM4 and AM5 sockets. It targets 1U server deployments and compact workstations where vertical clearance is limited. The side-blower layout pushes heat directly toward case exhaust rather than recirculating it internally. Buyers who need a cooler for Intel platforms or for high-TDP desktop CPUs above 95 W should look elsewhere.

Thermals Noise and Power Draw

A vapor-chamber base spreads heat into a skived copper fin stack driven by an 80 mm PWM blower spinning at up to 8600 RPM. At full duty cycle the fan moves 26.25 CFM and the assembly is rated to dissipate 95 W of CPU heat. Acoustic output rises with speed; in a 1U chassis the airflow path is short so the fan often runs near maximum. The unit draws power from a standard motherboard PWM header.

Bundled Hardware and Software Impact

The package supplies the heatsink, the integrated 80x80x13 mm blower fan and the AM4/AM5 mounting hardware required for installation. No additional brackets, thermal compound tubes or control software are included. The PWM fan allows the motherboard to regulate speed automatically based on CPU temperature. Users who want RGB lighting, software fan curves or a second fan for push-pull must source those separately.

Questions about this item

How do I install the Dynatron A42 on my AM4 or AM5 motherboard and what step is often missed?

Mount the cooler using the standard AMD retention frame, then connect the 4-pin PWM fan header; the step often missed is setting the fan to PWM mode in BIOS so the 8600 RPM blower can regulate speed automatically.

What maintenance will the copper skived-fin heatsink and vapor chamber base need over time?

The sealed vapor chamber requires no refill; periodically clean dust from the 80 mm side-blower fins with compressed air to maintain the 26.25 CFM airflow at full duty cycle.

At what point does the 95 W TDP limit become the bottleneck during sustained loads?

When the CPU continuously dissipates more than 95 watts, the copper heatsink and vapor chamber cannot move heat fast enough, so temperatures will rise despite the 8600 RPM blower running at full speed.
