Therefore, your drives are either refrigerated > or your measurements are suspect. 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..... James Carver
