Well not excactly!
heres how i tell which fan would be better
now fans move air in CFM = Cubic Feet Per Minute look at different fans and there CFM the one you see with the highest say 35.4cfm thats a good one, go ahead and buy it! you should get a pci fan blower too it goes into a pci slot and sucks the air out of the vent

you can even put this under a pci-e card and it will take the air off that and blow it out for better cooling power
