The 40x40x12mm Aluminum Water Cooling Block is a high-efficiency thermal management solution designed for liquid cooling systems. At Electrapac, we recommend this block for hobbyists and engineers looking to upgrade from air cooling to superior liquid heat dissipation for compact high-heat components.

Product Overview

This cooling block acts as a high-performance heat exchanger. By circulating liquid through its internal flow channels, it carries heat away from a surface far more effectively than standard aluminum fins. It is ideally sized for modern CPUs, high-performance GPU chips, and high-power thermoelectric (Peltier) modules.

Key Features for Electrapac Customers

• M-Shaped Water Channel: The internal flow path is designed in an "M" pattern to increase the surface area contact between the water and the aluminum, maximizing heat transfer efficiency.

• Leak-Proof Vacuum Brazing: The parts are fused using advanced vacuum brazing technology, ensuring a completely sealed unit that can withstand the pressure of standard water pumps.

• Mirror-Polished Base: Both sides of the block are precision-polished to be perfectly flat, reducing the "thermal gap" between the chip and the cooler when used with thermal paste.

• Corrosion Resistant: The aluminum alloy is treated to resist oxidation, ensuring long-term reliability even when used with standard distilled water or specialized coolants.

• Lightweight Design: At only 12mm thick, it is perfect for low-profile enclosures or "sandwich" style builds where space is at a premium.

Installation & Setup Guide

To get the best performance from your purchase at www.electrapac.com:

1. Tubing: Use flexible silicone or PVC tubing with an internal diameter (ID) of 7mm to 8mm for a snug, leak-free fit on the barbs.

2. Thermal Interface: Always apply a thin, even layer of high-quality thermal grease (TIM) between the component (CPU/TEC) and the cooling block.

3. Pump Selection: Pair this with a small 12V DC water pump to maintain a steady flow rate. Excessive pressure is not required; constant circulation is the goal.

4. Clamping: Ensure the block is held firmly against the heat source using a bracket or spring-loaded screws for optimal heat conductivity.

Primary Applications

• PC Hardware: Cooling for Northbridge/Southbridge chips, VRMs, or small GPUs.

• Thermoelectric Projects: The perfect partner for TEC1-12706 Peltier plates to create DIY mini-fridges or water chillers.

• Industrial LED Cooling: Managing the high heat output of 50W–100W COB LED arrays.

• 3D Printers: Water-cooling the hot-end to prevent heat creep in high-temperature printing environments.
