A fwiw tid bit when shopping for electric fans...........
Years ago there was no common industry standard for rating electric automotive fans, I presume the same situation today. Most companies use a cfm rating, often expressed in free-flow and not when placed behind a radiator. You can never know for certain about different cfm ratings or how a company has rated their fan since they can be tested by different criteria and methods. For comparison between brands using cfm ratings alone can be difficult, typically might not be apples-to-apples.
