I would like to overclock my 955 from 3.2hgz to around 3.6ghz-3.8ghz, but I don't think the stock cooler will be able to handle it. As it is it already creeps up close to 60c under load. On top of that, the stock cooler is very loud when it revs up during gaming. What would be a good cooler for around $50 or less? I would prefer to use the existing mounting bracket so I don't have to take out the motherboard, but my purchase is not dependent on it. Looking around it seems like a lot of people are recommending the Hyper 212+.
