ASRock CPU cooler 1U for socket AM4 passive

When rack space is at a premium and silence is non-negotiable, this ASRock 1U passive cooler steps in where active solutions fail. Built specifically for AMD AM4 processors with a modest 35W thermal envelope, it eliminates moving parts entirely — no fan, no bearing wear, no dust buildup, and absolutely zero noise. The solid aluminium fin stack is engineered for maximum surface area within a 1U height restriction, ensuring reliable heat dissipation in dense server chassis, compact workstations, and fanless HTPC builds.

Highlights

• Passive cooling for AMD AM4 CPUs up to 35W TDP
• 1U rackmount-compatible low-profile design
• All-aluminium construction for efficient heat transfer
• Zero moving parts — completely silent operation
• Screw-down mounting system for secure installation
• Ideal for servers, workstations, and home theatre PCs

In daily use

Installation is straightforward: the cooler screws directly onto the AM4 backplate, and because there is no fan cable to route, cable management stays clean. In a 1U chassis with proper airflow, the heatsink keeps a Ryzen 3 or Athlon processor within safe temperatures under sustained load. For home theatre enthusiasts, this cooler pairs perfectly with a low-power APU to create a silent media centre that never distracts from the soundtrack.
