Yes your stock cooler will work but compared to other aftermarket coolers it not goinf to be sufficient. At least from the standpoint of getting the coolest temps possible so as to insure longer component life. Hopefully your ram is low profile. At least for these three recommendations. First is the Swfttech Polaris120, it is only available from the Swiftech website. This will cost around $ 50.00 - $58.00. That is total price. But it will even cool a 4.7 Ghz processor. I am using two right Now. Then there is the Thermaltake Nic 5. Last is the cheaper of the three the, coolermaster Hyper 212 EVO. It is much better than stock but not as good as the other two. But it is cheaper. The Swiftech is the best.
