HD0 is my 80GB IDE and HD1 is the new SATA I put in today. They're as far as possible from each other at the moment, my case isn't good with two HDDs

Is this too hot? And this is just idling, chatting, IE, etc.
I was moving about 40GB worth of files and HD0 did reach 50 a couple of times. Right now HD0 only has program files and Windows on it. HD1 has everything else.
