* Increased Cooling Capacity: Two fans provide significantly more airflow than a single fan of the same size. This is crucial for quickly dissipating heat from the radiator, especially during stop-and-go driving or in hot weather where the engine is under higher thermal stress.
* Redundancy: If one fan fails, the other can still provide sufficient cooling to prevent overheating, although performance might be slightly reduced. This redundancy increases the vehicle's reliability and reduces the risk of a catastrophic engine failure due to overheating.
* Improved Low-Speed Cooling: At low speeds, a single fan might struggle to move enough air. Two fans, even running at a lower speed each, can provide adequate cooling in these situations.
In short, dual radiator fans offer a safety margin and better performance compared to a single fan, ensuring the engine stays within its optimal operating temperature range under various driving conditions.
