CFM. That's umm...I forgot but it's a volume over time measurement
so it's like gallons per minute of air but some metric version.I appreciate that you share your cooling tips but people complaining may not have read your post half way because of your writing style.
Take note :
Most people don't want to waste time reading about all your little inner thoughts.
PS : "Cubic Feet per Minute" is very self explanatory and common knowledge.
