Specifications side by side

How to choose the right one

1. Check server height limits

   You must match the heatsink height to your chassis. Dynatron offers 1U, 2U, and 3U options. The 1U models measure one inch tall. The Dynatron A25 and A28 fit tight spaces but rely on case airflow. If you need more clearance, the A26 stands six inches high. The A50 reaches 4.33 inches. Verify your rack or tower supports the specific U-rating. Mismatched heights prevent installation. Always check physical dimensions before ordering. The listed height determines compatibility with your server frame.

2. Select passive or active cooling

   Decide if you need fans or silent operation. Passive models like the A25 use copper to dissipate heat without moving parts. This ensures zero noise. Active models like the A26 use fans for higher thermal output. The A28 uses a vapor chamber for efficient passive transfer. The A50 includes a PWM fan for active cooling. Choose passive for silent server rooms. Choose active for high TDP processors. The cooling method defines your noise profile and thermal capacity. Check the attributes for this distinction.

3. Compare base materials

   Material choice affects weight and heat transfer. Copper conducts heat better than aluminum. The A25 and A28 use copper bases. The A28 adds a vapor chamber for faster spread. Aluminum models like the A26 and T17 are lighter. The A26 weighs only one pound. The T17 weighs two pounds. Copper adds mass but improves passive efficiency. Aluminum reduces weight for easier handling. Select copper for maximum passive performance. Select aluminum for lighter active setups. The material defines the thermal mass.

4. Verify socket SP3 compatibility

   All listed Dynatron heatsinks support Socket SP3. This socket is used by AMD EPYC processors. You do not need to check individual compatibility lists. Every model in this guide fits SP3. Ensure your motherboard uses this socket. The A25, A26, A28, T17, and A50 all work. This simplifies your selection process. Focus on height and cooling method instead. Socket mismatch is not a concern here. Confirm your CPU uses SP3 before buying. This ensures the mounting hardware fits your board.

5. Assess weight for handling

   Heatsink weight impacts installation and shipping. Lighter models are easier to handle. The A26 weighs one pound. The A28 weighs 1.01 pounds. Heavier models provide more thermal mass. The A25 weighs 1.3 pounds. The T17 weighs two pounds. Heavier copper blocks hold more heat. Lighter aluminum blocks are easier to mount. Consider your case support strength. Heavy passive coolers need sturdy mounting. Light active coolers are less demanding. Check the weight spec for logistics.
