Seems most likely to be a displaced or detached sensor, or a wonky sensor.

Given that the environmental-level "emergency" shutdown is based on 
that thermal reading going out of spec, I'd ping the folks at HP 
services (if that's an option here) and ask them about this reading, 
and let them sort this out.  (I don't have an AlphaServer DS10 service 
manual nor the IPB handy to check that.)  If that thermometer is 
reading ~20C low, then the "emergency" shutdown is not going to trigger 
until rather hotter than typical.  (And if you do get the magic smoke 
from your microprocessor, you've told HP services, and allowed them to 
decide how to resolve this.)
