Water block Alphacool Core 1 Black Brass Copper 72mm

The Alphacool Core 1 Black is a compact water block engineered from brass and copper to deliver efficient heat transfer for processor cooling. Measuring 72mm x 72mm x 26.5mm, this water block combines a solid construction with a matte black finish that integrates unobtrusively into custom liquid-cooling loops. The choice of brass and copper ensures corrosion resistance where required and high thermal conductivity where it matters most.

Advantages

The Core 1 Black uses a copper contact surface for direct thermal conduction and a brass housing for mechanical strength and durability. Its compact footprint supports dense mounting arrangements and enables efficient coolant flow across the cold plate. The black finish provides a neutral aesthetic that suits various case interiors without adding bulk or excessive weight.

Suitable for

• Cooling desktop processors in custom liquid-cooling loops
• Small-form-factor builds where compact cooling components are required
• Enthusiast systems requiring durable metal construction and reliable heat transfer

Key specifications

• Type: Water block for processor cooling
• Materials: Copper contact surface with brass housing
• Dimensions: 72 mm x 72 mm x 26.5 mm
• Weight: 0.54 kg
• Colour: Black finish

How to use

Mount the water block onto the processor according to your motherboard and mounting bracket instructions, ensuring the contact surface is clean and flat. Apply an appropriate thermal interface compound on the CPU heatspreader, position the block, and secure it with the compatible mounting hardware. Connect inlet and outlet fittings to your loop’s tubing, verify correct flow direction, and perform a leak test before powering the system.

Recommendations

Use corrosion-inhibited coolant compatible with copper and brass components, maintain regular coolant changes, and check fittings and seals periodically. Ensure mounting pressure is even to avoid uneven contact and to maximize thermal transfer efficiency.
