Hmmmm. An > interesting point of view. The drives are overly sensitive to temperature compared to almost any other drive from another manufacturer. Whether or not this is in spec or out is debatable. Nevertheless, if the drives are run 2 to 3 degrees hotter, if the were within less than 2-3 degrees of heat death anyway, they'll die. Moral 1: Don't buy these drives. They suck. Moral 2: If you unknowingly have already violated moreal 1, then you probably need to put another fan in your case OR you need to put the drive in a shoebox or other seperate case OR you need to rearrange your installed hardware to get it the best heat dissapation.
