Without the specs I can't say for sure. But with most modern CPU's with the exception of maybe a Pentium D you can get away with moderate OC'ing using the stock HSF.
Stock HSF's have gotten a lot better the last couple of years and power consumption and heat has been reduced in CPU's. To the point I would worry about getting a third party HSF until you see that the stock one isn't going to cut it. Or you fully plan on doing some major OC'ing, particularly when you know you are going to start raising the voltages. That's when the extra heat really starts to kick in.
