I had a heat problem as well and lost a drive to the heat.  My solution 
(condensed):

1.  Installed external thermometers from Fry's - $13 each - and attached 
the sensors to the CB of the drives.

2.  Bought hard drive coolers - again from Fry's.  I thought the 2 fan 
ones would be best - they were junk.  Replaced them with the cooler with 
the biggest fan I could find.  Can't remember the mfr - sorry - but it 
was a major name like thermaltake.

3.  The case has 7 fans already (4 in front, one on side, 2 in back.  I 
reversed the airflow on the one on the side to push air in instead of 
blowing it out.

4.  Placed a room fan near the computer (it's in a closet) to blow cool 
air into the closet.

5.  Set up a script that uses smartctl to alert me when the temperature 
of the drives got too hot.  The script checks the drive temp every 5 
minutes.

Have not had a problem since I did #2, and #3.
