Fekuar 6-Inch Slim Radiator Fan — 650 CFM 12V 80W, Low-Profile Push/Pull Cooling for Tight Engine Bays

The Fekuar 6-inch slim radiator fan is a high-flow, low-profile 12V cooling fan designed to replace or upgrade radiator setups in tight engine bays, delivering up to 650 CFM with a 10-blade design for efficient airflow.

If you need a compact, powerful fan that fits where larger units won’t, this Fekuar slim fan offers a low-profile solution for classic cars, hot rods, and modern builds. Its slim housing allows installation in cramped spaces while still moving substantial air to support the radiator, A/C condenser, intercooler, oil cooler and transmission cooler. The fan is engineered for both push and pull configurations and is compatible with many V6 and V8 engines commonly found in American classics and performance builds.

How much airflow and power does this fan provide?

The Fekuar slim fan produces a maximum airflow of 650 cubic feet per minute (CFM) and runs on a 12V, 80W motor, giving strong air movement from a compact package. It uses a 10-straight-blade layout to balance airflow and noise while maintaining durability for automotive environments.

• Maximum airflow: 650 CFM
• Voltage/power: 12V, 80W motor
• Blade count and type: 10 straight blades for steady airflow
• Diameter: 6 inches measured blade-to-blade

Will this slim fan fit my tight engine bay or classic car?

Yes — the slim profile is intended for installations where depth is limited, making it ideal for small radiators, tight shrouds, or modified engine compartments. It’s suitable for many hot rods and classic American engines, and can be mounted as either a push or pull fan to match your setup.

• Slim design: optimized for limited-clearance installations
• Fitment: universal mounting options for push or pull use
• Common compatible engines: widely used with Chevy, Ford, Buick, Pontiac, Cadillac and GMC V6/V8s
• Works with radiators, condensers, intercoolers, and oil/transmission coolers

How is installation handled and what configurations are supported?

Installation is straightforward for anyone familiar with aftermarket fans: mount the slim unit to the shroud or radiator support, wire to a switched 12V source or fan controller, and choose push or pull orientation. The fan’s compact depth gives more flexibility for placement and engine modifications without sacrificing airflow.

• Mounting: compatible with standard fan brackets and universal hardware
• Orientation: supports push or pull configurations interchangeably
• Electrical: 12V wiring for direct or controller-driven operation
• Space advantage: frees room for engine accessories and modifications

What components and systems will this fan help cool?

The fan is designed to aid cooling across multiple systems in the engine bay by directing airflow through heat exchangers and around hot components. It helps maintain airflow through the radiator and A/C condenser, and can assist intercoolers, oil coolers, and transmission coolers when mounted appropriately.

• Primary: radiator airflow to support engine coolant temperatures
• Secondary: A/C condenser efficiency when stationary or slow-moving
• Additional: intercooler, oil cooler, and transmission cooler assistance
• Application: suitable for both street and restored classic vehicle setups

Who is this for? The Fekuar 6-inch slim 650CFM fan is aimed at car restorers, hot rod builders, and performance-minded drivers who need a space-saving but powerful cooling solution. It’s particularly useful for owners of classic American V6 and V8 engines, tight engine bays, or anyone upgrading cooling for A/C or auxiliary heat exchangers. If you want a versatile push/pull fan that balances compact size with strong airflow, this fan is designed to meet that need without adding bulk to your engine compartment.
