Know before you buy
Yes, the EK-Quantum Volume³ FLT 240 is designed to align with standard 120mm fan mounting patterns, making it easy to secure to your case's fan brackets or radiator mounts.
This unit uses a standard 3-pin 5V digital LED header. Please ensure your motherboard or controller supports 5V D-RGB, as connecting it to a 12V RGB header will cause permanent damage to the LEDs.
The reservoir features nine G1/4" ports strategically placed around the unit. This provides significant flexibility for routing your tubing, whether you are using a simple loop or a more complex multi-component setup.
The flat-style design is engineered for easy access. The construction allows for straightforward maintenance, ensuring you can flush and clean the reservoir effectively to keep your loop running optimally.
No, this is a standalone reservoir unit. You will need to purchase a separate pump or a pump-reservoir combo if you do not already have a pump integrated into your custom cooling loop.
This reservoir has a capacity of approximately 250ml. While compact, this is sufficient for most standard custom loops while maintaining a slim profile that fits well in tighter builds.
