Is my ReadyNas Pro running too hot?
Upgraded my disks and they appear to be running pretty hot. Ambient temp is around 78F. If this is too hot, what can I do to help? Thanks, Stu Device Description ...

The above temps were with the side panels off, after putting them back on, the temps are lower, but I'm wondering if still too high?
I think they are ok (after all the datasheet does say 5-60C operating range). Lower temps might be better, but I wouldn't void the warranty or do anything heroic to get them.
Your temperatures are typical for enterprise class drives. Yours draw ~11 watts when reading/writing, ~6 watts when idle (http://www.hgst.com/tech/techlib.nsf/techdocs/FD3F376DC2ECCE68882579D40082C393/$file/US7K4000_ds.pdf).
Whether this is "too hot" is an area of disagreement here. Netgear (and others) say that since it's within the spec'd temperature range the disks, everything should be fine.
On the other side of the question, there is at least one study that suggests that temps in this range will reduce drive lifetime somewhat. Personally, I find some merit in that study, and want to keep my drives in the low 30s C.
Achieving that with your drives would require trying to customize the fan controls (which likely voids your warranty), and/or significantly lowering the ambient temperature in the room (which of course is expensive). I think I'd just accept the risk that I might need to replace drives a bit more often, and consider the question again when the time comes to replace them.
What I did myself was to choose drives that have lower performance, but which are much cooler (WDC Reds).
