No, those fans are placed there so that they can cool the HDs and the case at the same time.
I have the same setup in my case and I don't have any problems with cooling.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on 😱
 
I have this exact case, and it cools better than anything I've ever owned. (It's also a great case, overall.)

I have two hard drives and I intentionally mounted them behind that fan. Cooler hard drives is good. And don't forget, there are four other fans in the case, ensuring good air flow.



<-----Insert witty sig line here.
 
Plus! Even if you dont' mount fans in the openings by the hard disks, with a bit of airflow management, you will still get airflow through there, cooling those hard disks.
