EKWB is releasing pumpless versions of the Quantum Line pump-reservoir combo units – the EK-Quantum Kinetic FLT D5/DDC Body D-RGB and the EK-Quantum Kinetic TBE 200 D5 Body D-RGB. This means the customer can attach his already owned DDC or D5 pump allowing for a more affordable upgrade process from the previous generation of reservoirs. EK-Quantum products come with sophisticated 5V D-RGB addressable LEDs which can be controlled through your motherboard RGB control software.

These models are pumpless versions of the EKWB EK-Quantum Kinetic FLT pump-reservoir combos. They come in three sizes, 120mm, 240mm, and 360mm. They are mounted from the backside using the 120mm fan mounting holes and due to having no pump at the back. Each is compatible with both the D5 and DDC pumps and they come with separate mounting kits for your pump of choice, so if you decide to switch the pump model in the future, you can do that without replacing this combo unit. EK-Quantum Kinetic FLT pump-reservoir combos come with four G1/4″ ports on the front, and two on the bottom side as an optional IN and OUT.
