Hard drives ALWAYS run hotter than the ambient temp inside the case. The
faster the hard drive RPM's the hotter it is going to run. It is just a fact
of life. no matter how well something is lubricated, it is stiff going to
produce friction, which we all know friction=heat. If you are running fast
hard drives they will run hotter. it is a good idea to make sure that there
is plenty of air flow around them to help cool the drives they will always be
warm to the touch, but should not be running "hot". if they are to hot to
touch, you are shortening the lives of the drives. What I used to do on my
file servers that were loaded to the max with drives was to cut holes in the
cases so that I could put ducted fans directing cool air at the drives. (15
Machines with 4" ducts to each of them) It wasn't pretty but it worked.....
