Thanks for the reply.
Yup! Looks like I didnt think things through while ordering the 7200rpm drive As for now I have two solid blocks of copper the length of the drive stuck to the label side of the drive with thermal paste. Seems to be keeping it 10c cooler. But still high. I may go the route of eSata external, because my external drives are much cooler. We'll see!
Curious if WD's feature Reduced Power Spinup will benefit me at all with operating temperatures? Will it reduce it while only spinning up or while operating the whole time?
