RAIJINTEK copper brass radiator - 65mm thickness, CALORE C240D & C360D, is made of copper brass with high-density copper fin design and brass tank. CALORE radiator is engineered with an extremely thick 65mm radiator along with a triple-row 14-set flat tube design and brass tank. Fin design is optimized for efficiently pulling heat away from the power-dissipating components thus achieving maximum heat dissipation at both low and high airflow operation. With 2 or 3pcs 120mm high-static pressure fans, the radiator is manufactured from premium-quality materials that provide exceptional performance, unrivalled reliability. The unique stainless steel side panels guarantee the durability as well as reduce the weight of the radiator. Integrated G1/4" threads make it easy to install, while rigid connections ensure leak-resistant measures are in place. Square Fan anti-vibration rubber is provided to eliminate most vibration from fan.
