Speed Fan Temps!? Just added new heatsink + paste, now high temps!?

Computer was getting overly hot, and i broke my old heatsinks fan, so i never wrote down the temps before i replaced it.

But these are my temps now, one normal, and one while i was running a 1080p video, which the computer was made for, so i'm not pushing it.
