Dynatron R5 CPU Cooler 840556074373 The Dynatron R5 CPU Cooler is a high-performance server CPU cooling solution designed for Intel® Core™ X-series processors and Intel® Xeon® processors using LGA 2011 (Square ILM) and LGA 2066 sockets. Built for 2U and up server environments, it features a copper base with H.C.C. (Heatpipe Contact CPU) technology and embedded heatpipes to efficiently dissipate heat up to 165W TDP. The cooler is equipped with a 60x60x25mm PWM side-blow fan delivering up to 8000–8500 RPM, providing strong airflow and high static pressure for dense heatsink fins. For maintenance or replacement needs, the Dynatron DF126025BH-PWMG is the official compatible replacement fan for the Dynatron R5 CPU Cooler, allowing easy servicing without replacing the entire heatsink assembly.
