TEC1-12704 Peltier Thermoelectric Cooler Plate – 12V 4A Mid-Power Cooling Module

Overview

The TEC1-12704 is a high-quality thermoelectric cooling module designed for applications that require a steady, reliable temperature drop without the extreme heat waste of higher-amperage plates. Because it draws 4 Amps, it is perfectly matched for standard 12V 5A power supplies, leaving a safe 20% overhead for the rest of your circuit. It is widely used in medical devices, high-end scientific instruments, and custom-built cooling solutions for overclocked PC components.

Key Features

• Balanced Performance: Provides approximately 35-40W of cooling power while remaining easier to keep stable than 6A+ modules.

• Standard 40mm Fit: Universal size (40 times 40 mm) ensures compatibility with almost all Peltier water blocks and heatsink kits.

• High Efficiency: Better “Coefficient of Performance” (COP) than larger modules, meaning you get more cooling per watt of electricity used.

• Quiet & Eco-Friendly: Solid-state design uses no moving parts and zero refrigerants or CFCs.

• Long Lifespan: Designed for thousands of hours of operation when paired with a proper heat dissipation system.
