AM4 air cooler for 3U servers

The Dynatron A19 is an aluminium stacked-fin heatsink with heat pipes and an 80 mm PWM fan built for AMD Socket AM4 processors. It fits within a 110 mm height envelope and is rated for CPUs up to 165 W TDP, making it suitable for 3U rackmount chassis and workstation builds.

Suited to compact rack and workstation builds

This cooler targets system integrators assembling 3U or taller rackmount servers and workstations that use AM4 CPUs. Builders needing a lower profile for 1U or 2U chassis, or those requiring quieter acoustics than the 43.4 dBA maximum, should consider alternative low-profile designs.

110 mm maximum cooler height

The 110 mm overall height is the critical dimension that determines whether the A19 clears the chassis lid and adjacent components in a 3U enclosure. Verify the available vertical clearance in your specific case before purchase.

Questions about this item

What motherboard socket must I have for the Dynatron A19 to mount correctly?

The cooler is built for AMD Socket AM4, so your motherboard must expose that exact socket for the mounting hardware to engage.

Will the 110 mm height of the A19 fit inside my existing 3U server chassis?

At 110 mm tall the unit matches the typical clearance of a 3U rack enclosure, leaving enough room for the 80 mm fan to draw air without fouling the chassis lid.

How can I confirm the PWM fan is responding to CPU load after installation?

Connect the 4-pin header, then watch the speed ramp from 1000 RPM at idle toward 3800 RPM under load while noise rises from 16.0 dBA up to 43.4 dBA.
