Dynatron A46 Passive 1U Cooler for AMD AM4 AM5 socket up to 145W

Dynatron A46 — Passive Cooler for AMD AM4/AM5

Passive cooling is key for environments where quiet operation is a priority, such as 1U servers or compact systems. Designed specifically for AMD Ryzen™ processors with AM4 and AM5 sockets, the Dynatron A46 has a capacity of up to 145 W TDP to ensure reliable heat dissipation even at high performance. Thanks to its copper fins and vapor chamber design, it achieves effective heat dissipation, all while measuring a minimal 110 × 80 × 26.9 mm, which is ideal for limited spaces. This cooler delivers the combination of quiet operation and efficiency that professionals demand.

Efficient cooling with passive design

Thanks to its passive design, the Dynatron A46 is the perfect choice for systems where it is not possible to install active fans, or where silent operation is an emphasis. The copper and vapor chamber construction allows for fast and efficient heat dissipation, while the pre-mixed Shin-Etsu 7762 thermal paste facilitates installation and ensures optimal heat transfer between the processor and the cooler.

Compatibility and optimization for 1U systems

The Dynatron A46 is designed specifically for 1U servers and compact systems where space is limited. With a height of just 26.9 mm, it easily fits into even the lowest rack configurations. Full compatibility with AMD Ryzen™ processors and AM4 and AM5 sockets ensures that the cooler exactly matches the specifications of modern processors.
