  • Supports AMD AM4 and AM5 sockets
  • Handles up to 105W TDP for high performance
  • Vapor chamber base improves heat transfer
  • 8700 RPM blower fan delivers 26.25 CFM airflow
  • Fits 1U servers with 13 mm fan height

1U Vapor-Chamber Cooler for AMD AM4/AM5

The Dynatron A45 is a low-profile active air cooler built for 1U server chassis and similar space-constrained systems. It mounts on AMD Socket AM4 and AM5 platforms and handles processors rated up to 105 W TDP. A copper heatsink with an integrated vapor-chamber base spreads heat quickly to the stacked fin array.

Upgrade from Stock Low-Profile Coolers

This unit replaces basic OEM coolers that cannot sustain 105 W in a 1U form factor. The vapor-chamber base and 8700 RPM side-blower fan deliver 26.25 CFM at full duty cycle, making the step up worthwhile when thermal headroom is needed for sustained workloads in dense racks.

Check Chassis Height and Fan Header

Verify the chassis provides at least 13 mm clearance above the CPU socket for the 80 mm PWM blower. Confirm the motherboard supplies a standard 4-pin PWM header for fan control. Ensure the mounting pattern matches the AM4/AM5 retention mechanism before ordering.

Questions about this item

What server height does the 1U cooler require?

It is built for 1U chassis and up, so any rackmount case with at least one rack unit of vertical clearance will accept it

How is the side-blower fan connected and oriented during installation?

Mount the cooler on the AM4 or AM5 retention frame, plug the 80 mm PWM fan into the motherboard CPU fan header, and ensure the blower exhaust points toward the chassis sidewall

When should the 8700 RPM blower fan be replaced?

Replace the fan only if bearing noise appears or airflow drops noticeably below the rated 26.25 CFM at full duty cycle
