In the box

• CPU-XPR-DDC-I DDC Pump Reservoir CPU Water Cooling Block Combo: 1
• Mounting Hardware: 1
• 5v Addressable RGB LED (RBW)
• Thermal paste

Installation

• Remove the existing CPU cooler and clean the old thermal compound off the CPU.
• Fit the adjustable metal backplate behind the CPU socket.
• Apply the included thermal paste.
• Place the block on the CPU and secure it with the included mounting hardware.
• Connect the inlet and outlet ports to your loop with G1/4 fittings.
• Fill the reservoir through the fill port and close it.
• Connect the addressable RGB lighting cable.

Warnings

Thermal paste goes on the CPU's integrated heat spreader; never use thermal pads there.

Tighten the mounting screws in a cross pattern, finger tight. Over-tightening can crack the acrylic top or bend the socket retention frame.

The lighting plugs into a 5V 3-pin addressable (ARGB) header or an ARGB controller only. A 12V 4-pin RGB header will damage it.
