Looking for a cooler for my X2 555 that's unlocked to an X4. The max I want to spend is around $30 but I might be willing to go higher if there's something significantly better. Would like something reasonably quiet that will allow me to overclock to around 3.6-3.8 while unlocked as a quad. I was looking at the Hyper 212+ at Fry's for $30 but I figured I'd ask here first. Would this be the best cooler for the price or should I be looking at something else?
