Specifications
The reservoir, with the pump attached, measures 215 x 68 x 472mm and holds approximately 787ml—ideal for professional-grade cooling loops. It
features 27 integrated D-RGB LEDs, offering vibrant color options such as Acid Green, Blue, Green, Orange, Pure Clear, Purple, Red, and Yellow. The D-RGB cable is 800mm long, with a standard 3-pin connector (+5V, Data, Blocked, Ground) for broad compatibility with RGB controllers.
The integrated D5 PWM pump utilizes an electronically commutated spherical motor, operating at 12V DC with a power consumption of 23W. It delivers a maximum pressure head of 3.9 meters and a flow rate up to 1500 liters per hour, handling system temperatures up to 60°C. The construction uses premium materials: stainless steel, PPS-GF40, EPDM O-rings, aluminum oxide, and hard coal, ensuring durability and reliability. Power is supplied via SATA and 4-pin PWM FAN connectors, with PWM duty cycle ranging from 20% to 100%; default operation is at full power if no PWM signal is present.
