Design with Radiator Fan 12V 80W in Cirkit DesignerThe Radiator Fan 12V 80W is a high-performance cooling device designed to dissipate heat effectively from engines, radiators, or electronic components. Operating at 12 volts and consuming 80 watts of power, this fan ensures efficient airflow to maintain optimal operating temperatures. Its robust design makes it suitable for automotive applications, industrial machinery, and custom cooling solutions for high-power electronics.
This circuit is a temperature control system that uses a W1209 thermostat module to regulate a Peltier module and a 12V fan. The 12V power supply provides power to the W1209 module and the fan, while the W1209 controls the Peltier module based on temperature readings.

This circuit consists of a Peltier module and a 40mm 12V fan, each powered by their own dedicated 12V power supplies, indicating that they are likely used for a cooling application where the Peltier module generates a temperature differential and the fan dissipates heat. Additionally, there is a water pump powered by a 9V battery, which suggests that this circuit may be part of a system that requires liquid circulation, possibly for cooling or heating purposes.

This circuit consists of two 12V fans wired in parallel. Both fans share a common power supply connection, with their +12V pins connected together and their -12V pins also connected together. There is no microcontroller or additional control circuitry involved, indicating that the fans are intended to run continuously when power is applied.

This circuit connects a 120mm 12V DC fan to a 12V 7Ah battery. The fan's positive and negative terminals are directly connected to the corresponding positive and negative terminals of the battery, allowing the fan to operate at its rated voltage.
Open Project in Cirkit DesignerBelow are the key technical details and pin configuration for the Radiator Fan 12V 80W:
| Parameter | Specification |
|---|---|
| Operating Voltage | 12V DC |
| Power Consumption | 80W |
| Current Draw | ~6.67A (at 12V) |
| Airflow | 1200 CFM (approx.) |
| Fan Speed | 3000 RPM (nominal) |
| Dimensions | 120mm x 120mm x 25mm |
| Connector Type | 2-pin (positive and ground) |
| Operating Temperature | -20°C to 70°C |
| Noise Level | 35 dB (typical) |
| Material | ABS plastic housing, aluminum blades |
| Pin Number | Wire Color | Description |
|---|---|---|
| 1 | Red | Positive terminal (+12V DC) |
| 2 | Black | Ground (GND) |
To control the fan using an Arduino UNO, you can use a transistor or MOSFET as a switch. Below is an example circuit and code:
// Define the PWM pin connected to the MOSFET gate
const int fanPin = 9;
void setup() {
pinMode(fanPin, OUTPUT); // Set the fan pin as an output
}
void loop() {
analogWrite(fanPin, 128); // Set fan speed to 50% (128 out of 255)
delay(5000); // Run the fan at 50% speed for 5 seconds
analogWrite(fanPin, 255); // Set fan speed to 100% (255 out of 255)
delay(5000); // Run the fan at full speed for 5 seconds
}
| Issue | Possible Cause | Solution |
|---|---|---|
| Fan does not spin | Incorrect wiring or no power | Verify wiring and ensure 12V power supply is functional. |
| Fan spins but airflow is weak | Obstruction or incorrect mounting | Check for obstructions and ensure proper alignment. |
| Excessive noise or vibration | Loose mounting or damaged blades | Tighten screws and inspect blades for damage. |
| Fan overheats or stops working | Overvoltage or insufficient current | Use a regulated 12V power supply with adequate current rating. |
