Extra cooling needed for extra harddrives?

[hombrewdude]

I currently have a Server sized case with dual fan 500 watt power supply.
I added the cheap fans to all the ports the case has.
I currently have 3 SCSI drives 2 CD/DVD

I am about to add 4 more SCSI drives.
What other cooling options do I have?
Harddrive coolers any good?
Are there upgrades to the cheap plastic case fans?

Any suggestions?

Just put a 80mm fan in front of the 4 hard drives, by drilling a single hole.

Don't most servey cases have a fan blowing over the hard drive cage, mine has two..

And the sign says "You got to have a membership card to get inside" Huh
So I got me a pen and paper And I made up my own little sign</pre><p></font color=red>

Mine is not a true server case.
it is the size, and can hold the extra storage and HD space.
it is actually an older AT style case
