Dynatron A55 aluminum heatsink with heatpipes and PWM fan for AMD EPYC SP6 3U server

Dynatron

Dynatron A55 AMD SP6 3U CPU cooler 225 W

SKU CH-KCPC-77M2S MPN A55

Active air cooler with aluminium stacked fins and heat pipes handles 225 W TDP for AMD EPYC SP6 CPUs in 3U servers

  • Designed for AMD EPYC processors using SP6 socket
  • Aluminium stacked-fin heatsink with embedded heatpipes moves heat efficiently
  • 4-pin PWM fan adjusts speed to thermal load
  • Rated for 225 W TDP in 3U server chassis
  • Dual ball-bearing fan built for continuous operation

Socket SP6 compatibility

The Dynatron A55 is an active air cooler built for AMD EPYC processors using the SP6 socket. It fits 3U server chassis and workstations where a low-profile thermal solution is required. The unit handles a thermal design power of up to 225 Watts. Buyers needing coolers for other socket types or taller rack heights should look elsewhere.

Clearance and mounting checks

Verify that your chassis provides enough height for a 3U form factor and that the motherboard layout matches the SP6 mounting pattern. Confirm the fan header on your board supplies a standard 4-pin PWM signal for speed control. The aluminium stacked-fin array with embedded heatpipes requires unobstructed airflow through the rack. Systems lacking these physical or electrical provisions cannot use this cooler.

Thermals and acoustics

A dual ball-bearing fan regulated by 4-pin PWM adjusts speed to match load, keeping the EPYC CPU within its thermal envelope at 225 W TDP. The aluminium heatsink and heatpipe construction moves heat away from the die efficiently during sustained workloads. Ball bearings reduce wear compared with sleeve designs, supporting continuous operation in server environments. Noise level varies with fan duty cycle under PWM control.

Questions about this item

Does the A55 cooler ship with mounting hardware for AMD SP6 sockets or must I source it separately?

The Dynatron A55 is designed for AMD SP6 sockets and includes the necessary mounting hardware for installation on compatible EPYC processors.

Should I choose this A55 model for a 225 W TDP EPYC CPU or is a different version needed?

This A55 model is rated for up to 225 W TDP, making it the correct choice for EPYC processors operating at that thermal limit.

What does the 225 W TDP rating mean for actual cooling performance inside a 3U server chassis?

The 225 W rating indicates the cooler can dissipate that thermal load using its aluminum stacked fin array, embedded heatpipes and PWM-controlled fan within a 3U form factor.
