Dual 12” High Performance Fan
Originally created as original equipment for the Maserati Quattroporte high performance sedan, the new SPAL USA Dual 12” High Performance Fan (#30102130) is now available in the U.S. The fan uses one high performance motor and one extreme performance motor to achieve a maximum airflow of more than 2,900 cubic feet per minute (cfm). A special shroud on the fan assembly helps to improve airflow while driving at highway speeds.
Like all SPAL fans, the Dual 12” high performance model features rigid, glass-filled nylon fan blades – dynamically balanced internally and externally to minimize vibration – and a robust steel and aluminum casing. The entire assembly offers high heat and vibration resistance and is fitted with sealed waterproof connectors.
Application
The Dual 12” High Performance Fan has a slim profile. It measures only 27” across, making it a perfect fit on many muscle car and full-size truck radiators. It is especially suited to mid-generation muscle cars – including the Chevelle – as well as Corvettes and vehicles using large core radiators (28”-30”).
Fan-PWM
SPAL USA’s FAN-PWM is a revolutionary, custom-programmable fan controller that allows a single SPAL cooling fan to vary speed based on engine temperature – thereby increasing fan life while decreasing under hood noise.
Simply choose a “Low” and “High” temperature setting. When the “Low” setting is reached, the fan begins spinning at 50% speed. As the engine temperature increases, the speed of the fan increases until it reaches the “High” setting, where it is running at 100% speed.
Application
The FAN-PWM is designed for fans with up to 25 amp draw. When used with a dual fan, one of the fans is variable speed while the other is on/off (with additional Fan Relay Harness – FRH). “PWM” refers to “pulse width modulation.” The FAN-PWM was originally designed to optimize cooling in hot rods but can be used in many applications. It is great for use in modern computer controlled vehicles.
Sensors
The FAN-PWM can utilize the OEM water temperature sensor, or a gauge sensor, thereby eliminating the need for a second sensor. A SPAL USA temperature sensor is available separately if the application requires a second sensor.
Air Conditioning
When used with air conditioning input, it activates both fans at full-speed when the air conditioning is turned on.
Temperature Settings
Generally, the “Low” setting is at or around 170° F and the “High” setting between 205°-210° F (15° above thermostat). Practically, the “Low” setting will be a minimum of 30° below the “High” setting to allow the controller to vary fan’s speed. The temperature limits will depend upon the sensor used, or factory system the controller is connected to.
Features
- Weatherproof construction
- Can be set to any temperature
- LED indicators for “High”, “Low” and “A/C”.
- Can be mounted inside the vehicle or in the engine bay
Benefits
- Variable speed can be used to reduce fan noise when desired
- Variable speed helps extend the overall life of the fan (SPAL USA fan life ranges from 4,000 to 40,000 hours depending on fan type)
- Easy to program

“Low” Setting 50% 50% (on only one fan)
“High” Setting 100% 100% (on both fans)
