Is there any advantage to having two similar fans strapped together on the same fan slot?
Like for example two 1800rpm/23CFM on the exhaust port, both puling air from the case through the same grill.
[edit] Wouldn't adding a second fan do the same as replacing one fan for a longer fan?

If so what should the total CFM and noise look like?
Appreciate any help.

Increasing the speed increases the air volume but it also increases the noise.
By adding another fan under 2000rpm there should be no noticeable increase in noise.

I think that you can/should only use a push/pull setup when you're using a radiator for water cooling.
This is not my case .

Maybe he has one fan hanging out the back of his case :)
Or, for front fans that are between the case and the front bezel, I've wondered about putting one on the other side of the hard drive bays pulling the air from the other side.
