Thanks! One additional question - how does one remove the current cooler? I've tried simultaneously pushing the two small, spring-loaded, hexagonal pins but the cooler won't budge.
You are going to need to take out the board and turning it over then pinch the ends of the push pins while pushing them out. Then the cooler should fairly easily come off, don't worry if the stock compounds has to strength to it. It will pop off at that point. Be sure to clean the chipset before installing the new cooler.
