I bought a nice big fan, $5 or $6 .. then installed in front of where
the drives are mounted, this helped cool down the harddrives. Heat is
really bad, the more components you add, the more heat to get rid of. I
recently had to remove the cover from mine til I get some unit fans to
move the air out.

You can try using the Secondary or another controller if you have one.
This may help isolate the motherboard.  Your hard drives might be okay
if the controller is bad.  I'd try the drive in another computer if you
don't have access to a spare controller.
