Dynatron A49 4U CPU Cooler AMD AM4 AM5 170W

SKU CH-J7CQ-6WJ4X

4U active cooler with heatpipes and double-ball bearing fan dissipates 170 W for AMD Ryzen AM4 and AM5 sockets

  • Designed for AMD Ryzen AM4 and AM5 sockets
  • 4U server form factor fits standard rack chassis
  • Heatpipe contact technology transfers heat directly to aluminium fin stack
  • Double ball bearing fan ensures long service life
  • Dissipates up to 170 watts of CPU thermal output

Targeted Server Cooling

The Dynatron A49 is a 4U active air cooler built for AMD AM4 and AM5 sockets. It uses heatpipe contact technology with an aluminium base and fin stack to dissipate up to 170 watts of CPU heat. The double ball bearing fan is rated for continuous operation in rackmount environments. This unit suits system integrators deploying Ryzen processors in 4U or larger server chassis.

Mounting And Airflow Impact

The supplied AM4/AM5 mounting hardware secures the cooler directly to the motherboard retention frame. Because the design relies on front-to-rear airflow through the fin stack, the chassis must provide a clear path from the front intake to the rear exhaust. No additional brackets, thermal paste syringes or fan splitters are mentioned in the manufacturer data.

Clearance And Power Checks

Verify that your 4U chassis internal height accommodates the cooler without contacting the side panel or intruding on DIMM slots. Confirm the motherboard CPU socket keep-out zone leaves room for the aluminium base footprint. Ensure the fan header on your board can supply the required current for the double ball bearing motor. Buyers needing support for sockets other than AM4 or AM5 cannot use this cooler.

Questions about this item

Will the double ball bearing fan need replacement after long-term use?

Double ball bearings generally last longer than sleeve bearings under continuous operation, reducing the likelihood of early fan replacement.

What thermal limit applies when running a 170W CPU continuously?

The cooler is rated to dissipate up to 170 watts, so sustained loads at or near that level are within its design capacity.

How much noise and heat should I expect from the fan running all day in a 4U server?

The double ball bearing fan provides reliable airflow for 4U chassis; heat output matches the CPU load up to 170W, while noise varies with fan speed and case ventilation.
