First, never buy sunbeam, I wouldn't trust any of my components to them... Cooler master is the most suggested, but if you plan to really overclock go for the xigmatek. This is my bigges suggestion to you though:http://www.newegg.com/Product/Product.aspx?Item=N82E168.... It runs really cool and its silent. How do I know? Its the one I have, I can't hear it, even running its fan at max, my cpu never goes above 42 C. Which is pretty good. Just make sure you buy some good thermal paste along with the cooler. I would suggest IC Diamond.
