Maintain optimal temperatures with our Peltier modules. These distinctive electronic components have the ability to create a temperature gradient when supplied with power. In simple terms, applying 12V to the red (positive) and black (negative) wires results in one side becoming cold while the other side heats up. They are commonly employed to regulate the temperature of high-end processors by positioning the colder side on the processor ICs and directing the hotter side towards the exhaust fan to effectively dissipate heat.
