## Summary description

Dynatron W21 is a 2U CPU cooler designed for Socket 5964 systems. The unit supports switchable active/passive operation, allowing either fan-assisted or passive cooling depending on system needs. It is intended for rack or compact server builds where 2U height is required, offering flexible thermal management for compatible Intel platforms using socket 5964.

## Long description

Dynatron W21 is a 2U CPU cooler engineered for systems using Socket 5964. Designed for rack and compact server environments, the unit provides switchable active/passive operation so cooling behavior can be adapted to workload and chassis airflow. Its low-profile 2U form factor fits standard 2U server slots while delivering contact and heat dissipation appropriate for compatible Intel platforms using Socket 5964.
Advantages
The switchable active/passive design enables operation with a fan for higher thermal loads or passive mode when acoustic or redundancy considerations require fanless operation. The 2U height ensures compatibility with constrained rack spaces and compact chassis. The cooler is built to provide reliable contact with the CPU heatspreader and efficient thermal transfer within the 2U envelope, helping to maintain processor temperatures under varying server conditions.
Suitable for
2U rackmount servers and blade enclosures that require low-profile CPU cooling
Systems based on Intel Socket 5964 processors where controlled thermal management is needed
Environments that alternate between fan-assisted and passive cooling modes for noise or redundancy reasons
Key specifications
Form factor: 2U low-profile cooler suitable for 2U chassis
Socket compatibility: designed for Socket 5964 processors
Cooling modes: switchable active (fan-assisted) and passive operation
Intended use: server and compact rack systems with constrained vertical space
How to use
Install the cooler according to the server chassis and motherboard mounting points compatible with Socket 5964. Ensure the CPU and cooler contact surfaces are clean and apply thermal interface material as specified by the system builder. Secure the cooler firmly to provide even pressure on the CPU heatspreader. For active operation, connect the fan power connector to the appropriate header and verify fan control in BIOS or system management firmware. For passive operation, switch the unit to passive mode following the manufacturer instructions and confirm adequate chassis airflow and temperature monitoring to prevent thermal throttling.
Usage recommendations
Monitor CPU temperatures after switching between active and passive modes. Use active mode during sustained high-load periods or when chassis airflow is limited. Use passive mode where low acoustic profile or fan redundancy is required, ensuring case ventilation and system monitoring remain sufficient to maintain safe processor temperatures.
