EK-Quantum Convection DDC - Gold is an aluminum heatsink for DDC pumps with a real gold plating. This add-on vastly improves the cooling performance of the motor and electronics and thus prolongs the lifespan of the water pump. It is made of CNC-machined aluminum that is nickel-plated, followed by second plating with genuine gold. Optimal heat transfer is ensured by the use of an enclosed thermal pad. Due to its metallic construction and finned design, the EK-Quantum Convection DDC amplifies the effect of airflow therefore placing the water pump in front of any fan or radiator will dramatically improve the cooling performance. This product is compatible with the following products: DDC 3.2 and DDC 4.2 pumps EK-QUANTUM KINETIC FLT DDC SERIES FLAT PUMP-RESERVOIR COMBOS EK-Quantum Kinetic FLT 120 DDC PWM D-RGB - Plexi EK-Quantum Kinetic FLT 240 DDC PWM D-RGB - Plexi EK-Quantum Kinetic FLT 360 DDC PWM D-RGB - Plexi EK-QUANTUM KINETIC TBE DDC SERIES TUBULAR PUMP-RESERVOIR COMBO UNITS EK-Quantum Kinetic TBE 120 DDC PWM D-RGB - Plexi EK-Quantum Kinetic TBE 160 DDC PWM D-RGB - Plexi EK-Quantum Kinetic TBE 160 DDC PWM D-RGB - Acetal EK-Quantum Kinetic TBE 120 DDC PWM D-RGB - Acetal Enclosed: - EK-Quantum Convection DDC - Thermal pad - Mounting screws Model: 3831109895405
