Reservoir combo for liquid-cooled PCs

The Bitspower Hercules 150mm Reservoir Combo integrates a pre-installed K2M pump into an acrylic reservoir body. Digital RGB lighting runs along the top edge and is certified for ASUS AURA Sync, GIGABYTE RGB Fusion 2.0, MSI Mystic Light Sync, ASRock Polychrome, BIOSTAR VIVID LED DJ and Razer Chroma. Sturdy aluminium brackets allow direct mounting on top of a radiator to save internal space.

Pump voltage and lighting control limits

The integrated pump operates on a 12V DC rated voltage with an 8 to 20V operating range. Digital RGB effects require a compatible 5V addressable RGB header or supported controller software from one of the certified motherboard ecosystems. Acrylic construction demands compatible coolants to avoid cracking or clouding over time.

Mounting clearance and header availability

Verify that your case provides enough vertical room above the radiator for the 150mm reservoir height and included tank clamps. Confirm the motherboard offers a 5V addressable RGB header or a supported RGB controller for the certified sync software. Ensure the power supply can deliver stable 12V DC to the pump within the stated operating window.
