Water block Alphacool Core 1 LT Acetal Copper Black 72mm

The Alphacool Core 1 LT Acetal Copper Black 72mm is a compact CPU water block combining an acetal polymer housing with a nickel-plated copper base to provide effective cooling for modern desktop processors. At 72 mm wide and deep and 26.5 mm high, the Core 1 LT uses a 3D jetplate together with cross-slot technology and internal O-rings to direct coolant flow and dissipate processor waste heat. The unit is available in non-illuminated and transparent aRGB versions and includes a revised mounting system compatible with Intel and AMD sockets.

Advantages

The Core 1 LT pairs a redesigned 3D jetplate with proven cross-slot coolant distribution to ensure even flow across an enlarged copper base for full CPU coverage. The polymer (acetal) housing reduces weight while retaining structural stability. Internal O-rings improve flow control and sealing. The simplified mounting system requires fewer screws and supports Socket AM5, Socket AM4 and LGA 1700 for easier installation on recent motherboards.

Suitable for

• Cooling desktop processors in custom water-cooling loops
• Compact PC builds where a 72 mm water block footprint is required
• Systems using Socket AM5, Socket AM4 or LGA 1700

How to use

Before installation, prepare the motherboard and CPU according to the motherboard manufacturer’s instructions. Pre-assemble the backplate (for Intel platforms) using the provided four spacers. Apply thermal paste to the CPU surface, place the matching mounting frame over the water block and secure it with the four nuts on the spacers or the included AMD mounting hardware. Integrate the water block into your closed loop with appropriate fittings and tubing, then fill and bleed the loop to remove air before powering the system.

Recommendations

Use compatible coolant and correct-size fittings; verify socket compatibility (AM5, AM4, LGA 1700) before purchase. Ensure the loop is leak-tested and bled thoroughly and follow torque guidelines for mounting screws to avoid damage to the CPU or board.
