Hey guys, I've looked at a couple reviews and they show either winning. Which is the better cooler for my AMD Athlon II X4 640. Also, on the OCZ website it says the vendetta is only for AM2, but then i read that the AM3 and AM2 mounting is the same. Will I have any trouble installing this? Also, will i have to get any additional brackets to do so? Also, which is quieter?
