DNA Motoring Dual 12-Inch Electric Radiator Cooling Fans with Thermostat Relay Kit – RAF-12X2+SW-KIT

Slim 12-Inch Fan Design for Tight Engine Bays

Each fan features an advertised 12-inch diameter and 2.5-inch thickness.

The slim profile is intended for installations where space between the radiator and engine accessories is limited.

Why Slim Fans Matter

In many vehicles, radiator clearance is restricted by:

• Water pump pulleys.
• Accessory drive belts.
• Engine-mounted fans.
• Turbocharger piping.
• Intercooler plumbing.
• Custom engine swap components.
• Radiator support structures.

A slim electric fan can provide additional installation flexibility.

However, fan depth alone does not guarantee fitment.

Before ordering, measure the available space and account for the fan motor, mounting brackets, wiring, and required clearance from moving engine components.

Universal Push and Pull Fan Configuration

The DNA Motoring RAF-12X2+SW-KIT is advertised as supporting both push and pull configurations.

Pull Configuration

A puller fan is installed behind the radiator, typically on the engine side.

It draws air through the radiator core toward the engine compartment.

This is the advertised default configuration.

Push Configuration

A pusher fan is installed in front of the radiator.

It pushes air through the radiator core toward the engine compartment.

This arrangement may be useful when there is insufficient clearance behind the radiator.

Which Configuration Is Better?

A properly installed puller fan is often preferred when sufficient clearance is available.

However, the correct configuration depends on radiator packaging, fan design, airflow requirements, and surrounding components.

The supplied description states that fan polarity can be changed for push/pull operation.

Important: Reversing electrical polarity does not necessarily produce optimal airflow in both directions. Confirm the manufacturer’s instructions regarding blade orientation, motor rotation, and approved push/pull conversion before installation.

Automatic Thermostat-Controlled Fan Operation

One of the most useful features of this kit is the included temperature-controlled fan switch.

Instead of requiring the driver to manually turn the fans on and off, the switch is designed to activate the relay circuit when the monitored temperature reaches its specified threshold.

Fan Temperature Switch Settings

How the Temperature Switch Works

When the temperature at the switch reaches approximately 180°F, the switch activates the fan control circuit.

The fans then operate to increase airflow through the radiator.

When the temperature falls to approximately 165°F, the switch opens and the fans shut off.

This temperature difference helps reduce rapid cycling.

Important Installation Requirement

The manufacturer specifies that the temperature switch must be installed in a properly grounded engine location.

The switch must also contact the appropriate coolant passage or temperature-sensing location.

Do not install the switch into an arbitrary threaded opening without confirming coolant contact, thread compatibility, sealing requirements, and proper electrical grounding.

12V Relay Wiring Kit for Reliable Fan Control

Electric radiator fans can draw substantial current during operation, especially when starting.

The DNA Motoring kit includes a 12V relay wiring system intended to support automatic fan activation.

Why Use a Relay?

A relay allows a low-current control circuit to operate a higher-current electrical load.

This helps avoid routing the full fan motor current through a small temperature switch or dashboard control.

A properly configured relay circuit can provide:

• Automatic fan activation.
• Appropriate electrical switching.
• Reduced load on the temperature switch.
• Convenient integration with a vehicle’s 12V electrical system.
• Reliable operation when installed with suitable wiring and circuit protection.

Circuit Protection Matters

The kit advertises an included circuit breaker.

Electrical protection should be selected based on the actual current requirements of the fans, including startup current.

Important: The supplied listing does not confirm whether the kit includes separate relays or independently protected circuits for each fan. Verify the wiring harness, relay capacity, circuit breaker rating, and wire gauge before installation.

DNA Motoring RAF-12X2+SW-KIT Technical Specifications

Specification note: The manufacturer does not clearly state whether the advertised 1,550 CFM airflow and 6.67-amp draw are per fan or for the complete pair. Confirm these values before sizing the wiring, relay, and circuit protection.

What’s Included in the DNA Motoring Dual Fan Kit?

According to the supplied product listing, the package includes:

Confirm the exact package contents before purchasing, particularly the number of relays, fuse or breaker ratings, wiring connectors, and temperature switch components.

Universal Electric Radiator Fan Applications

The DNA Motoring dual 12-inch fan kit is designed for universal applications.

This means it is not guaranteed to bolt directly into every vehicle.

Instead, it can be adapted to compatible radiator and engine bay configurations.

JDM and Import Performance Cars

Electric cooling fans are popular among enthusiasts modifying vehicles such as:

• Honda Civic and Acura Integra.
• Nissan 240SX and Silvia.
• Toyota Supra and MR2.
• Subaru WRX and STI.
• Mitsubishi Lancer Evolution.
• Mazda RX-7 and Miata.

Compatibility depends on radiator dimensions, engine bay clearance, and cooling requirements.

Classic American Muscle Cars

Dual electric fans are also popular in classic Chevrolet, Ford, and Mopar builds.

Common applications include custom cooling systems for:

• Chevrolet Camaro.
• Chevrolet Chevelle.
• Chevrolet Nova.
• Ford Mustang.
• Chevrolet C10.
• Custom small-block and LS-swapped vehicles.

Electric fans can offer packaging flexibility when replacing older mechanical fan arrangements.

Engine Swap Projects

Custom engine swaps often require changes to radiator placement and fan clearance.

A slim electric fan system may help accommodate:

• LS engine swaps.
• Honda K-series swaps.
• Turbocharged engine conversions.
• Custom radiator installations.
• Modified engine accessory layouts.

Before installation, verify that the fans provide sufficient airflow for the engine and radiator combination.

Electric Radiator Fans and Air Conditioning Performance

The supplied description advertises cooling benefits for the radiator, air-conditioning system, intercooler, oil system, and transmission fluid.

However, electric radiator fans do not directly cool all these components.

Their primary function is to move air through the radiator and any adjacent heat exchangers positioned in the airflow path.

Radiator Cooling

The fans move air through the radiator core to help dissipate engine coolant heat.

Air Conditioning Condenser

When installed behind or in front of a condenser and radiator assembly, properly positioned fans can help move air through the A/C condenser.

This may support air-conditioning performance during low-speed operation.

Transmission and Engine Oil Coolers

If transmission or engine oil coolers are positioned in the fan’s airflow path, the fans may help improve airflow across those heat exchangers.

Intercoolers

Air-to-air intercoolers generally rely on airflow through their own heat exchanger.

A radiator fan may influence intercooler airflow only when the components share an appropriate airflow path.

The kit should not be advertised as directly cooling the entire engine bay or every fluid system.

How to Install the DNA Motoring Dual 12-Inch Cooling Fan Kit

Installing universal electric radiator fans requires careful planning.

The exact procedure depends on the vehicle, radiator dimensions, fan placement, and electrical system.

Step 1: Measure the Radiator

Before installation, measure the radiator core and available mounting area.

Confirm that two 12-inch fans can fit without contacting surrounding components.

Allow adequate clearance for the fan motors, wiring, and mounting hardware.

Step 2: Choose Push or Pull Configuration

Determine whether the fans will be installed in front of or behind the radiator.

Follow the manufacturer’s approved procedure for configuring the fan direction.

Verify airflow direction before final installation.

Step 3: Install the Fan Mounting Hardware

Secure the fans using the supplied mounting components where appropriate.

Avoid placing excessive stress on radiator tubes or fins.

For performance applications, a properly designed fan shroud or rigid mounting brackets may provide a more durable installation.

Step 4: Install the Temperature Switch

Locate an appropriate threaded coolant passage or approved temperature-sensing location.

Confirm that the switch is compatible with the thread size and coolant system.

Use the included adapter if required.

Verify proper electrical grounding.

Step 5: Install the Relay Wiring Kit

Disconnect the vehicle battery before wiring.

Mount the relay in a protected location away from excessive heat and moisture.

Use appropriate circuit protection, wire gauge, and grounding points.

Step 6: Verify Electrical Capacity

Confirm that the vehicle’s charging system can support the additional electrical load.

Account for the combined operating and startup current of both fans.

Do not assume the advertised 6.67-amp specification represents the complete dual-fan system.

Step 7: Test Fan Operation

Reconnect the battery after completing and inspecting the wiring.

Verify that both fans rotate in the correct direction.

Confirm that the temperature switch activates the fans at the intended temperature.

Inspect the wiring for excessive heat, loose connections, or interference with moving components.

Step 8: Monitor Engine Temperature

Run the engine while monitoring coolant temperature.

Verify that the fans activate and shut off as intended.

Confirm that the cooling system maintains appropriate operating temperatures under normal driving conditions.

If temperatures remain excessive, inspect the radiator, thermostat, water pump, airflow path, and cooling system condition.

Common Electric Radiator Fan Installation Mistakes

A properly installed electric fan system can improve cooling performance, but installation errors can reduce effectiveness.

Incorrect Airflow Direction

Fans installed in the wrong direction may move air against the intended airflow path.

Insufficient Radiator Coverage

Fans that cover only a small portion of the radiator may not provide adequate airflow for the engine.

Undersized Wiring

Wiring that cannot safely handle fan current can overheat and create electrical hazards.

Incorrect Relay Capacity

A relay that is not rated for the actual fan load may fail prematurely.

Poor Ground Connections

Weak or corroded grounds can cause intermittent operation or reduced motor performance.
