Need High CFM - Low db 80mm fan

[ChineseChef]

So, I bought a 16 bay jbod, and it has 2 super high cfm 80mm fans in the back, but they are server room loud.  So I was looking for some quieter ones that will still move enough air to keep the HDDs cool enough.  The units will be in a seperate room, so they don't need to be ultra quiet, but I would like as quiet as possible.  My key issue is that I don't know what fans or types of fans operate best at the kind of air pressures these fans will be under while trying to pull the air through the case.  This unit will not see heavy usage, at most 2 simultaneous users viewing media, but it will be completely filled with consumer grade 7200rpm HDDs.

 

I was looking at a few of fans, but I'm not sure if they would do the job or if there are better options??  While I do know plenty about computers, specific use case for fans is a bit out of my element.

 

Thanks in advance.

 

 

This is the jbod:

And here are the fans I was looking at:

Edit:

 

Should have mentioned, these look like the current fans in the unit.

That is certianly a nice fan, and I am rather impressed with your response time.  But it is only ~34 cfm, will that be enough to replace the current fans?

Taking a quick look at some retailers, that's about as much as you'll get from a no-brand 80mm fan, though obviously the noctua fan will be significantly quieter.

 

My suspicion is that you'll be able to get away with lower CFM/speed fans as long as your equipment isn't server-rack dense.
