In the box

• 1x CPU Water Cooling Block
• 1x Mounting Hardware
• 1x 5v Addressable RGB (RBW) lighting
• Thermal paste

Installation

• Remove the existing CPU cooler and clean the top of the processor.
• Fit the mounting hardware and metal backplate for your socket.
• Apply the included thermal paste.
• Place the block on the CPU and secure it with the mounting screws.
• Connect your loop fittings to the two G1/4 ports.
• Connect the 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.
