I highly recommend getting an upgraded HSF. I never liked the standard Intel "push-pin" style fans. I particularly like Thermaltake (but Zalman also rocks). You need something with good hardware, and most companies skimp when it comes to this. Check out the hardware that comes with the Big Typhoon from Thermaltake (this is an old build, but still a great HSF). This thing weighs over 2 pounds and doesn't budge!
