Dynatron A56 3U active server CPU cooler for AMD AM4 and AM5. Rated over 170W TDP with a direct-contact heatpipe base and an 80mm 8038 double-ball PWM fan — built for 3U rackmount chassis where a tower cooler won't fit. This is a high-airflow server cooler, not a quiet desktop unit.
Bought new May 2026, mounted in a home server about 10 days, then swapped out for a quieter cooler — nothing wrong with it, my partner could not tolerate the noise in the bedroom. Old thermal paste cleaned off; apply your own on install. Includes the AM4/AM5 mounting hardware. Smoke-free home.
