Product Details:

The Dynatron R5 2U Server Active CPU Cooler is designed for Intel Sandy Bridge EP/EX Processors up to 150 Watts. An H.C.C. (Heatpipes Contact CPU) copper base works in tandem with aluminum fins with 6mm heatpipes embedded to quickly transfer the heat from CPU while a 60mm dual-ball bearing PWM fan delivers quiet, efficient airflow for your cooling needs. The standard server board bolt-thru mounting mechanism and pre-applied thermal grease make this cooler easy to install as well.

• Intelligent H.C.C The Dynatron R5 2U Server Active CPU Cooler features a copper base that is in direct contact with the CPU to enhance heat conduction.
• 150-watt Cooling Colution Four 6mm heatpipes integrated with H.C.C (Heatpipes Contact CPU) copper base and high-density aluminum fins, plus an active side 2 ball bearing PWM fan, deliver up to 150 watts of cooling capability for Intel Sandy Bridge EP/EX Processors.
• RoHS Compliant The Dynatron R5 2U Server Active CPU Cooler is fully compliant with RoHS, and is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). You can enjoy the computing cooling effects with confidence in knowing no hazardous materials are included in the cooler.
• Energy-Saving PWM The PWM function automatically adjusts fan speeds according to the CPU temperature for efficient cooling, minimized fan noise as well as energy saving.
