Normal Hard Disk Temperature?

[palladium]

I have 2 HDDs in my rig, one 500GB Seagate Barracuda ( 500GB) and another WD 160GB from a 3 year old Dell. I ran HWMonitor, it reports 25C for the Seagate drive and 49C for the WD dirve. Vista is installed on the Seagate. I'm using Antec 900 case with both front fans on full speed.

Is 49C normal for a drive that is idling most of the time?

49c is hotter than I'd personally be comfortable with, but I don't know what is considered normal for that WD unit. My 3 HDs right now are at:

32c Seagate 320gb
29c WD 640gb AAKS
26c WD 74gb Raptor

Although my apartment is crazy-cold right now at 57F. When it's closer to 70F here they are usually around 37c (320gb) 35c (640gb) and 33c (74gb).

I'd try to rearrange the drives (if you have a lot of drive bays, leave an empty space between each) or improve the cooling, if possible.
