I have about 5 HDs running in an old PC I bought about 6 years ago. Its one of my main editing machines so I have a decent amount of HDD space. I took the side of the tower off so I can get more ventilation for the drives. When I turn it on and let it run for about an hour or two, the drives get so hot, you cant even touch them. I have a regular small house fan that I have positioned on the drives to cool them down. Is this normal? The computer has had its problems recently including one of the HDs went bad, but I just figured because it was a 5 year old drive or so. Any suggestions?
