I will be building a PC in a few weeks and I am looking for a cpu cooler for the cpu I am going to get, the Phenom II X4 955 Black Edition. The thing is, it needs to fit in the case I have, the NZXT M59 http://www.newegg.com/Product/Product.aspx?Item=N82E16811146058 . I think I will need to get something that is 150 MM tall or shorter. I would like to spend no more than around $30, I plan to overclock the cpu by adjusting the multiplier. I have been looking at the coolermaster Hyper 520n but I am unsure If it is good enough. What cpu cooler do you guys suggest? Or should I wait until I can spend a little more? Thanks.
