EK-Quantum Convection DDC - Black is an aluminum heatsink for DDC pumps. 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 anodized in black.Optimal heat transfer is ensured by the use of an enclosed thermal pad. Due to its metallic construction and finned design 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:EK-QUANTUM KINETIC FLT DDC SERIES FLAT PUMP-RESERVOIR COMBOSEK-Quantum Kinetic FLT 120 DDC PWM D-RGB - PlexiEK-Quantum Kinetic FLT 240 DDC PWM D-RGB - PlexiEK-Quantum Kinetic FLT 360 DDC PWM D-RGB - PlexiEK-QUANTUM KINETIC TBE DDC SERIES TUBULAR PUMP-RESERVOIR COMBO UNITSEK-Quantum Kinetic TBE 120 DDC PWM D-RGB - PlexiEK-Quantum Kinetic TBE 160 DDC PWM D-RGB - PlexiEK-Quantum Kinetic TBE 160 DDC PWM D-RGB - AcetalEK-Quantum Kinetic TBE 120 DDC PWM D-RGB - AcetalEnclosed:- EK-Quantum Convection DDC- Thermal pad- Mounting screws
