40×40mm Aluminum Water Cooling Block is a compact liquid cooling heatsink designed for Peltier thermoelectric cooling modules and other small high-performance thermal management applications. Made from lightweight aluminum, this water block transfers heat efficiently from compatible TEC modules to circulating water or coolant.

The water block is specifically suitable for 40×40mm Peltier modules such as TEC1-12705 and TEC1-12706. With two approximately 8mm hose connectors, it can be integrated into a DIY liquid cooling loop for Peltier refrigeration, CPU/GPU experiments, laser module cooling, and custom temperature control systems.

How It Works:

• Mount the water block against the 40×40mm surface of the Peltier module.

• Apply suitable thermal paste or thermal interface material between the contact surfaces.

• Connect two compatible hoses to the water block inlet and outlet.

• Circulate water or suitable coolant through the block.

• Heat is transferred between the Peltier module and the circulating liquid.

• Use a suitable pump, radiator, or reservoir to complete the cooling loop.

Installation Instructions:

• Ensure the water block and Peltier module surfaces are clean and flat.

• Apply a thin, even layer of thermal paste.

• Align the 40×40mm water block with the Peltier module.

• Secure the assembly evenly to maintain good thermal contact.

• Connect the inlet and outlet hoses securely.

• Check all connections for leaks before powering the system.

• Ensure adequate liquid circulation during operation.

Product Instructions:

• Check hose compatibility with the approximately 8mm connectors.

• Use suitable coolant for the intended application.

• Do not operate a liquid cooling system without adequate coolant flow.

• Check for leaks before connecting electrical power.

• Use thermal paste to improve heat transfer.

• Avoid excessive mechanical pressure that could damage the Peltier module.

• Keep the cooling loop clean to maintain efficient circulation.
