The FASTSTORM Electric Fan Relay Kit is an essential component for controlling an electric radiator fan, ensuring efficient cooling of your engine or vehicle system. This kit includes a temperature sensor switch that activates the fan at a specific temperature, providing automatic cooling for your engine. The kit is designed to be 60 AMP-rated, making it capable of handling the electrical load required by most electric fans, and it's built with waterproof materials to withstand harsh environments. Here's a detailed review of its key features, performance, and overall value.Key Features:60 AMP Relay: The 60 AMP relay in this kit is designed to handle the electrical current required to operate high-power electric cooling fans. This ensures that the relay kit can support most aftermarket electric fans, even those that demand higher power. The high amperage rating is ideal for vehicles with upgraded cooling systems or those that require more robust fan setups.Temperature Sensor Switch: The kit comes with a temperature sensor switch that turns the fan on at 185°F and off at 175°F. This allows the fan to operate only when necessary, maintaining optimal engine temperatures. The automatic control of the fan based on temperature eliminates the need for manual operation and helps prevent overheating by ensuring that the fan kicks in when the engine temperature reaches a critical point.Waterproof Design: The waterproof construction of the relay kit ensures that it can handle exposure to moisture, rain, or even harsh conditions. This makes the kit suitable for automotive, off-road, or marine applications, where exposure to water and humidity is common. It is an ideal choice for those who require a reliable cooling system in environments where weather conditions can be unpredictable.Complete Kit: The FASTSTORM relay kit comes with all the necessary components for installation, including the relay, temperature sensor, wiring, and fuses. This all-in-one kit simplifies installation and saves you time compared to sourcing individual components separately. It’s designed for DIY enthusiasts or those with basic knowledge of automotive wiring who want an efficient and cost-effective cooling solution.Easy Installation: The relay kit is easy to install, thanks to its clearly marked wiring instructions and pre-configured components. The kit is generally compatible with most vehicles and cooling fans, and the inclusion of necessary wiring and fuses ensures that the setup process is straightforward. The clear instructions make it accessible even for users who are not professional mechanics but are comfortable with basic electrical work.Durable Materials: The kit is made from high-quality materials, ensuring that all components are built to last. The relays, wires, and switches are designed to withstand heat, vibration, and wear over time, making them ideal for automotive environments. The weatherproofing ensures that the kit can continue functioning effectively even in outdoor or challenging conditions.Versatile Applications: While primarily designed for electric radiator fans, the FASTSTORM Relay Kit can also be used for other cooling fans, such as those used in cooling systems for trucks, off-road vehicles, or boats. This versatility makes it an appealing option for a wide range of vehicles and applications where temperature control is critical.Performance:Efficient Cooling Control: The temperature sensor switch activates the fan reliably at 185°F and deactivates it at 175°F, ensuring the engine stays within a safe operating temperature range. This automatic fan control reduces the likelihood of overheating, particularly during heavy engine use or in hot weather, improving the longevity and efficiency of the engine.Strong Relay Performance: The 60 AMP relay handles the power requirements of most electric fans without any issues. Users report that the relay operates smoothly without overheating, ensuring consistent fan operation during long drives or off-road excursions. The relay provides stable electrical connections and responds quickly to temperature changes, turning the fan on and off when required.Reliable in Harsh Conditions: The waterproof design ensures that the kit performs well in all types of weather, including rain, snow, or high humidity. This is especially beneficial for users in off-road or marine environments where the kit may be exposed to water splashes or even submersion. The waterproofing maintains the functionality of the relay, ensuring the fan operates as needed without being affected by moisture or debris.Solid Construction: The durable build of the components ensures that the relay, sensor, and wiring continue to work effectively even after extended use. The components are designed to handle the high temperatures typical of engine environments, and users generally report long-lasting reliability without any failure or degradation.Pros:60 AMP relay can handle high-power cooling fans, making it suitable for a variety of vehicle applications.Automatic temperature-based fan control eliminates the need for manual operation and helps prevent overheating.Waterproof design ensures reliable performance in wet or challenging conditions, making it perfect for marine or off-road use.Complete kit includes all necessary components for installation, including wiring, sensors, fuses, and relays.Easy installation with clear wiring instructions, making it accessible for DIY users.Durable and long-lasting components that are designed to withstand heat, vibration, and outdoor conditions.Versatile — suitable for a range of applications including automotive, off-road, and marine cooling systems.Cons:Temperature Range: The fixed 185°F on and 175°F off temperature range might not be ideal for all vehicles or specific cooling needs.
