See below for comments on the different temperatures you were interested in.

If you by this mean absolute temperature then it's not really possible since 
Intel nowadays report only a relative temperature. This new scale (AFAICT) 
defines negative temperatures as below the critical temperature for a cpu (0 
degrees). That is, -50 is ok (I think it means 50 degrees from critical). 
Note that this is for Woodcrests and newer (Xeon 51xx).

This can theoretically be extracted via SMART commands but the PERC 
controllers doesn't have a pass-through for commands such as smartctl :-( In 
fact, they sometimes suffer serious problems if you attempt to run smartctl 
on them (why they don't just ignore the for them unknown command is beyond

There are a few sensors you can read, the most interesting (IMO) is the 
ambient temperature. Actually, double checking, the 2950 only reports CPU and
