I am overclocking my chip to 4.6Ghz, for now. During the winter it was fine to use just the stock fan as I was pumping air in from outside (http://www.techspot.com/gallery/member-galleries/p4563-industrial-size-cooling.html). Now it's starting to warm up outside and my temps starting to reach unsafe levels with stock fan. I tried to find something on the web, Every cooling review I found is done on Intel chips and that's not good enough for me. Does anyone use the same as I with aftermarket cooler? What would you recommend? Thanks. My board is Gigabyte GA-990XA-UD3 if that matters to you.
