Reservoir and pump combo

The Bitspower XYZ Reservoir Lite combines a 215ml acrylic reservoir with an integrated K1M pump for custom liquid-cooling loops. It mounts directly on top of a radiator using the supplied aluminum brackets and mounting hardware. The dual-loop design provides additional routing options for tubing runs. Digital RGB lighting is compatible with major motherboard synchronization ecosystems.

Thermals noise and power

The K1M pump operates at a rated 12V DC with an operating range of 8 to 16V and draws 0.7A for 8.4W of power consumption. Acoustic output is rated at 24dBA under normal operation. Maximum flow reaches 7.7 LPM while the pump speed is specified at 460±15% L/h. The assembly is rated for continuous system temperatures between -25 and 80 °C with an MTBF of 15,000 hours.

215ml capacity constraint

The reservoir holds up to 215ml of coolant, which limits total loop volume for builders planning large or multi-radiator configurations. Physical dimensions of 220 by 85 by 50.5 mm require sufficient clearance above the chosen radiator for the bracket mounting system. Buyers needing greater fluid capacity or a remote pump mounting location should consider alternative reservoir designs.

Questions about this item

How do I mount the Bitspower XYZ Reservoir Lite on a radiator using the included aluminum brackets?

Attach the supplied brackets to the radiator with the provided screws, then secure the 220 mm long acrylic reservoir body on top; ensure the 215 ml tank sits level so the K1M pump inlet stays submerged during filling.

What maintenance does the K1M pump require and when should I plan for replacement?

The pump is rated for 15,000 hours MTBF at 24 dBA; inspect the impeller and clean the reservoir annually, and budget for a new K1M unit once continuous running time approaches that figure.

At what coolant temperature does the system hit its thermal limit during sustained load?

The K1M pump and reservoir are specified for a system temperature range up to 80 °C; sustained loop temperatures above that point exceed the rated operating envelope.
