I noticed the Mac Pro (2009) does not have any fans blowing directly onto the hard drives. How are the temperatures managed, I wonder? I have 3 drives installed. According to iStat, they are 104, 102, and 95 much of the time. The one at 104 runs hotter as it's an old Apple Maxtor from 2005. The 102 is the Apple WD drive that came with the Pro. What kind of temps are some of you seeing on your drives? What would be considered 'average' or 'healthy'?
