How the Alternatives Differ

Dynatron 2U Passive AM4 Heatsink

The Dynatron 2U Passive AM4 Heatsink supports both AM4 and AM5 sockets, unlike the Thermal Grizzly spreader which is AM5 only. This unit is a complete passive cooling solution measuring 6 inches on all sides, rather than a small 1.97 by 3.94 inch surface enhancement. It weighs 2 pounds and requires case airflow, whereas the Thermal Grizzly part relies on your existing cooler. You should choose this if you need a fanless setup for low-power AMD processors under 120 Watts. It sacrifices the direct thermal interface improvement of the spreader for a full heatsink design.

Dynatron 1U Copper Blower Heatsink

The Dynatron 1U Copper Blower Heatsink targets Intel LGA 2011 sockets, making it incompatible with your AM5 system. It is a 1U server heatsink made of copper, measuring 3.15 by 4.06 inches. This product is designed for narrow ILM Intel builds with low power needs. It offers no benefit for AMD Ryzen-7000 processors. The Thermal Grizzly spreader is a universal upgrade for compatible AM5 air and liquid coolers. You should only consider this Dynatron model if you are building an Intel LGA 2011 server chassis and need a compact copper solution.

Noctua NH-D9DX i4 3U Dual-Tower Cooler

The Thermal Grizzly spreader is a 0.5-inch thick nickel-plated copper plate that improves heat transfer for your current cooler. You should pick the Noctua if you are building an Intel Xeon system in a 3U chassis and need a low-profile air cooling solution.

Dynatron 1U Passive Vapor Chamber Heatsink

The Dynatron 1U Passive Vapor Chamber Heatsink uses a vapor chamber for heat transfer and supports Intel LGA 2011 sockets. It is a passive cooler measuring 2.4 by 5.2 inches, weighing 7.94 ounces. This unit is for narrow ILM LGA2011 server builds. It does not fit AM5 processors. The Thermal Grizzly spreader is a diamond-milled copper surface for AM5 that works with active coolers. You should choose this Dynatron model if you need a compact, high-capacity passive vapor chamber cooler for an Intel LGA 2011 server system where case airflow is available.

Dynatron 2U Active Aluminum SP3 Heatsink

The Dynatron 2U Active Aluminum SP3 Heatsink is built for AMD EPYC SP3 sockets, not AM5. It is an active cooler made of aluminum, measuring 4.5 by 5 inches. This unit is a lightweight 2U active cooler for server rack installations. It requires fans for operation. The Thermal Grizzly spreader is a passive nickel-plated copper enhancement for AM5 CPUs that fits under your existing cooler. You should select this Dynatron model if you are cooling an AMD EPYC SP3 processor in a 2U server chassis and need an active aluminum cooling solution.

Dynatron 2U Active CPU Cooler

The Seasonic Dynatron B13 2U Active Cooler is designed for 2U server builds with active cooling requirements. It measures 3.15 by 4.25 inches and is 2.6 inches tall. This product is a compact cooler for constrained chassis designs. It does not specify socket compatibility for AM5. The Thermal Grizzly spreader is a specific AM5 heatspreader that reduces temperatures by up to 10 degrees Celsius. You should consider this Seasonic unit if you need a 2U active cooler for a server chassis with height limits, rather than an AM5 thermal enhancement.
