Temperature Controlled Radiator Fans vs. Constant On Fans: A Comprehensive Guide
Introduction
Hey there, readers! Are you tired of your car overheating on a hot summer day or freezing on a cold winter night? If so, it might be time to upgrade your radiator cooling system. In this article, we’ll delve into the world of temperature controlled radiator fans and constant on fans to help you make an informed decision about which one is right for your vehicle.
Section 1: Temperature Controlled Radiator Fans
How They Work
Temperature controlled radiator fans are designed to turn on and off automatically based on the temperature of the engine coolant. When the coolant reaches a certain temperature, a sensor sends a signal to the fan to turn on. As the coolant cools down, the fan turns off. This system helps to maintain an optimal engine temperature and prevent overheating.
Benefits
- Improved cooling efficiency: Temperature controlled fans only operate when needed, which reduces drag on the engine and improves fuel economy.
- Reduced noise: Since the fans are not constantly running, they generate less noise, making your ride more comfortable.
- Longer fan life: By operating only when necessary, temperature controlled fans last longer than constant on fans.
Section 2: Constant On Radiator Fans
How They Work
As the name suggests, constant on radiator fans are always running, regardless of the engine coolant temperature. They are typically used in vehicles that operate in very hot climates or that require continuous cooling.
Benefits
- Consistent cooling: Constant on fans provide unwavering cooling, even when the engine is idling or at low speeds.
- Simplicity: Constant on fans are simple to install and maintain, making them a popular choice for older vehicles.
- Lower cost: Constant on fans are generally less expensive than temperature controlled fans.
Section 3: Which Type Is Right for You?
The best type of radiator fan for your vehicle depends on several factors, including:
- Climate: If you live in a hot climate, a constant on fan may be a better choice to ensure consistent cooling.
- Driving habits: If you frequently drive in stop-and-go traffic or idle for long periods, a temperature controlled fan can save fuel and reduce noise.
- Vehicle type: Certain vehicles, such as performance cars or heavy-duty trucks, may require constant on fans due to their high heat output.
Comparison Table
| Feature | Temperature Controlled Fans | Constant On Fans |
|---|---|---|
| Operation | Turn on and off automatically | Always running |
| Cooling efficiency | Improved | Consistent |
| Noise | Lower | Higher |
| Fuel economy | Better | Worse |
| Fan life | Longer | Shorter |
| Installation complexity | More complex | Simpler |
| Cost | Higher | Lower |
Conclusion
Whether you choose temperature controlled radiator fans or constant on fans, it’s important to install and maintain them properly to ensure optimal engine cooling. Consider your specific needs and driving habits to make the right choice for your vehicle.

FAQ about Temperature Controlled Radiator Fans vs Constant On Fans
What is the difference between a temperature controlled radiator fan and a constant on fan?
Answer: Temperature controlled radiator fans turn on and off automatically based on the temperature of the engine, while constant on fans run continuously regardless of the engine temperature.
Which type of fan is better?
Answer: Temperature controlled fans are more efficient and can help improve fuel economy, while constant on fans provide more cooling at the expense of fuel efficiency.
When should I use a temperature controlled fan?
Answer: Temperature controlled fans are ideal for vehicles that experience a wide range of operating temperatures, such as daily drivers and off-road vehicles.
When should I use a constant on fan?
Answer: Constant on fans are best for vehicles that operate at high temperatures for extended periods, such as race cars and vehicles used in heavy towing or off-roading.
How do I choose the right temperature setting for my fan?
Answer: The ideal temperature setting depends on the specific vehicle and engine. Consult your owner’s manual or a reputable mechanic for guidance.
Can I install a temperature controlled fan on a vehicle that currently has a constant on fan?
Answer: Yes, it is possible to upgrade from a constant on fan to a temperature controlled fan, but it may require additional wiring and sensors.
Will a temperature controlled fan make my engine run cooler?
Answer: In most cases, yes. Temperature controlled fans allow the engine to run at its optimal operating temperature, which can improve performance and longevity.
Will a constant on fan use more fuel?
Answer: Yes, constant on fans draw more power from the engine, which can result in reduced fuel economy.
Can I use a smaller fan if it is temperature controlled?
Answer: Generally speaking, yes. Temperature controlled fans can often be smaller than constant on fans because they only run when necessary.
Do temperature controlled radiator fans last longer?
Answer: Yes, temperature controlled fans typically last longer than constant on fans because they are not subjected to constant use and wear.
