Hard Disk Cooling over the Drivebay?

[castlegrayskull]

I seem to be having problems with a raid array in my Shuttle.
Is there a better way of cooling the disks in my system.
I'm using the two bays right at the top of the shuttle for my 2 disks.

System Spec:
Shuttle SB81P
Intel 3.0MHz (Prescott i think)
2 GB Dual Channel OCUK Ram
256Mb GF 7800GT (Leaktek)
2 x Hitachi Deskstar 76gb disks (striped)
random extra usb2 pci card
AOPEN DVDRW Drive

Problem
I origianlly had 2 disks running and very quickly one fell over .. this was the disk on top of the DVDRW.
I was running DIVXtoDVD fine on using one disk (while waiting for a replacement) but as soon as i get the new disk and rebuild the system across 2 disks i run into problems.
I left it on decoding some episodes of 24 during the day .. i came back and the whole thing had fallen over .. rebooted and it didn't recognise the array.
I had to go into the array (once the system was cool) and remind the array there was 2 disks ... only then would it boot back up fine into XP ?

anyone had similar problems .. or is this an one of ?

Cheers
Dave
