Please see the smartmontools FAQ about how to have your drive added.

In general, yes, raising drive temperature does lower lifetime. But do do
large numbers of lead/unload cycles!
I have read that in general, modern drives that use fluid bearings seem to
be less sensitive to failure from elevated temperatures than older drives
that used mechanical (ball) bearings.
For what it's worth, on my laptop I show 751000 cycles in 3000 operating
hours. Currently temperature 32 Celsius (drive spinning!).
