12in HO Extreme RAD Fan

The 12in HO Extreme RAD Fan from DERALE is a high-output electric cooling solution engineered for vehicles that demand serious thermal management. Whether you're running a modified engine with increased power output, upgrading a vehicle with marginal OEM cooling capacity, or building a custom hot rod, this 12-volt pushpull fan delivers the airflow needed to keep coolant temps in the safe zone. The "HO" designation signals high-output performance—this isn't a wimpy supplemental cooler, but a core piece of your engine's thermal regulation system.

Rated at 2000 CFM, the 12in HO Extreme RAD Fan moves serious volume of air across your radiator core, reducing engine strain and stabilizing operating temperatures under load. The curve blade design optimizes air acceleration while minimizing noise—a critical consideration for street and strip vehicles where driveability matters. At 3.5 inches thick with push/pull reversible mounting capability (13.125 x 13.125 inch shroud), this fan integrates into most radiator configurations and provides flexible installation options depending on your bay layout. The plastic construction keeps weight down at 7.15 lbs without sacrificing durability, and the 12V DC system ties seamlessly into either factory or aftermarket electrical harnesses with a basic relay setup.

This fan suits bracket racers, street machine builders, and anyone upgrading from belt-driven or undersized factory fans. Installation requires basic mechanical competency—secure the shroud to your radiator, mount the motor in push or pull configuration, and wire through a relay to your ignition and coolant-temp switch. The reversible design lets you optimize airflow direction based on your specific radiator type and engine bay constraints. For carbureted engines, EFI conversions, or turbocharged builds where cooling demand spikes quickly, the 12in HO Extreme RAD Fan delivers the CFM and reliability serious enthusiasts expect.
