Actually, 60C is a typical maximum spec for the environmental
temperature. It is expected that the internal temperature will exhibit some rise above the environment. I've got one drive that I felt was overheating in a poorly designed external enclosure. Displaying that drive's lifetime temperature excursions with "smartctl -l scttempsts" shows that it hit a lifetime high of 67C, but had zero instances of being over its temperature limit. That drive does have the usual 60C max environmental temperature spec. (I do have that drive in a better enclosure now.)
