Dynatron CPU Kühler 4189 2HE (270W)

Engineered for high-density 2U rackmount servers, this active CPU cooler delivers exceptional thermal management for Intel Xeon Scalable processors up to 270W TDP. Its copper base and aluminum fins ensure rapid heat dissipation, while the PWM-controlled dual ball bearing fan provides precise cooling from 1000 to 4500 RPM.

Advantages

The Dynatron N11 combines robust construction with intelligent fan control. The copper base maximizes heat transfer from the CPU, and the aluminum fin stack offers a large surface area for airflow. Dual ball bearings extend fan lifespan, and PWM support allows the motherboard to adjust fan speed based on load, balancing cooling performance and acoustics.
