Are my 3.5 internal hard drives too close to each? ..does it even matter?

Hey guys, just curious if this setup is ok with the hard drives being just about stacked on top of one another. They are each 1tb. I believe the mounting case they're in was meant for (2) hard drives, but I snuck the 3rd one in the middle space between the top and bottom drives that was prob meant for air flow. I have (1) cpu fan and (1) case fan at the rear blowing air out. Yay or nay?
