10in HO Extreme Electric Fan

The 10in HO Extreme Electric Fan from DERALE is a high-performance cooling solution engineered for serious engine builders, hot rod enthusiasts, and mechanics who demand precision temperature control in compact spaces. Whether you're running a street machine, restoration project, or performance build, this 10-inch electric fan addresses the critical cooling challenge that plagues modern and modified powerplants: inadequate airflow when idling or crawling through traffic. Unlike belt-driven mechanical fans that waste horsepower and generate excess heat, an electric fan engages only when needed, preserving fuel economy and keeping your engine within optimal operating range.

DERALE's 10in HO Extreme electric fan delivers efficient thermal management through a direct-drive brushless motor rated for high-output cooling capacity, making it suitable for both street and strip applications. The compact 13.2 x 3.1 x 16.35-inch profile and lightweight 3.34-pound construction allow installation in cramped engine bays where traditional mechanical fans simply won't fit—critical for mid-mounted radiators, tight custom fabrications, or vehicles with limited clearance. The extreme-duty design incorporates sealed bearings and thermal override protection, ensuring reliable operation across extended load cycles without premature wear or electrical failure, while the modular mounting system accommodates most radiator configurations with simple bracket adjustments.

This fan is ideal for builders working with custom radiator setups, vintage engine swaps, and high-output street engines where OEM cooling is inadequate or incompatible. Installation pairs best with a quality engine-mounted thermostat switch or aftermarket digital controller to optimize fan cycling and prevent thermal runaway during sustained acceleration or highway driving. Proper wire gauge selection and relay configuration are essential—consult wiring diagrams specific to your electrical system and ensure adequate battery capacity for consistent performance. The 10in HO Extreme electric fan represents a straightforward, cost-effective upgrade that pays dividends in reliability, engine longevity, and consistent performance across varying driving conditions.
