Message	Fans just cannot accurately replicate airflow compared to real life situations. That's a hell of a lot harder to test for (though it has been done by a few very dedicated people here). The data is still 100% appreciated though. More of it can paint a better picture even if it's not 100% perfect. www.SoCalZCrew.com - Come find out how we do it in the West!
