Hard drives are refrigerators, and run cooler than ambient? Sure about

Yes, I am. As I said, you should put them close to an exhaust fan to
pull warm air off them. The temperature sensors at the hard drive

The HD temperature CANNOT be lower than ambient unless there is some type
of refrigeration happening. 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.....

from sitting up here on the fence, I can see both sides to this discussion.

Take in to account, It all depends on where the ambient temp of the system is measured from. different areas inside the case have different temps.
obviously the area around the CPU, north bridge chipset and vga card WILL be warmer than other areas of the case.

There are also many other varying factors that can affect this too. System usage etc, etc.

.......My 2c deposited,
Carry on gentlemen !!!!.
