80 is too high-my old desktop shut off at 75. If the stock paste isn't working you can get silver compound. Also if you just put it on check the amount. If you put on too much heat isn't dissipated. You only need a thin layer. How are your fans directed? It would be best if the one on the front blows in and the one on back blows out. Also since heat rises I would put one on the top of the case blowing out if you have a hole there.
