Know before you buy
This reservoir is specifically engineered for Laing DDC series pumps. It attaches directly to the pump housing to create a compact, integrated cooling unit.
Yes, the included stainless steel frame is designed for 3.5-inch bay mounting. Alternatively, you can mount it vertically or use the integrated holes to attach it to an 80mm fan.
The unit features a dedicated top port specifically for filling. This makes it easy to add coolant without needing to disassemble your loop.
The bicameral design helps stabilize the coolant flow within the reservoir. This effectively prevents air bubbles from being pulled back into the pump, ensuring a quieter and more efficient loop.
Yes, it includes an integrated LED hole. This allows you to easily insert a standard LED to illuminate the coolant and customize the look of your build.
The reservoir measures 62 x 62 x 50mm. Its compact footprint is designed to match the form factor of the DDC pump, making it ideal for space-constrained builds.
