Im running an SFF and in the 3.5" bay i have a Raptor and 250Gig sata drive....im not at home to the post the temps...but im wondering how hot is to hot?
 
While most drives can operate at temps up to around 50C, anything over 40 will dramatically reduce the life of the drive. Ideally, you would keep them around the normal body temp of 37C/98F, or less if possible.
 
as a very broad rule of thumb
Each 10°C (18°F) temperature rise reduces component life by 50%
Conversely, each 10°C (18°F) temperature reduction increases component life by 100%.
thats the jist of the Arrhenius Equation and applies to mechanical devices as well a semiconductors, of course there is a minimum temperature mechanical devices need inorder to function too low and its contracted so much clearences are too tight.

there are of course other variables involved, thermal stress is one that comes to mind with HARD drives, ideally the smaller the rate of change from being up and running to being down and "cold"

thats also one of the reasons SCSI HDDs have a reputation for higher reliability
they are better made (generally and certainly in the past) but they where also typically always spun up and had a very consistent thermal environment

so basically avoid extremes as well as "peak" temperatures if you can
