I just replaced my AMD Phenom II X2 565 with an AMD FX 8350. I haven't overclocked my computer, it's still running at 4ghz. I have 3 large fans inside my chassis, just as I did with my last CPU. I'm also only using the stock cooler for the CPU, but that wasn't a problem with my last CPU, so why is this one so much louder?
