To answer your question about the ICH:
It again requires digging deep into the highly verbose Intel manuals.
The max. temperature for the ICH is 92 C, and MCH is 102 C or so.
So your in the 'safe' range.
What kind of fan arrangement do you have in your chassis? Whats the ambient room temperature?
I have had some success by having an intake fan directly blowing over the ICH (southbridge) - but then there are also dust problems.
