Really if it's stable there isn't tons to worry about unless you plan on keeping it for many years to come.
drdingo: When you make a claim of 30 it would be nice to see "with watercooling" next to it....I was thinking you were getting 30 with juts a HS/fan combo.
Be sure to use a good thermal grease or else you aren't helping enough. I believe ArcticSilver or something like that is one of the highest recommended ones.
