SP30 Specs.  I am looking for the specs for the maximum CFM air flow for the SP30. 

I know that the fan speeds are variable based on temperature/workload, but I am looking for the maximum CFM for the use of heat extraction from a hood vented racking system. It may be in a previous post but a quick search did not reveal for me and the specs on the website show "4x80mm" fans, but not maximum CFM.

Thanks for the help.
