]I was really tired of the jet engine sound coming from the stock AMD cooler.
so today I bought the Cooler Master Hyper 212 Plus. I was looking at Arctic Freezer 13 PRO as well but I chose Cooler Master for two reasons, first and most important was price, almost $20 cheaper for a similar product. and it has the highest cfm @76.8 with a dBA of 32 at top speed. that plus good reviews and easy install.
It's hard to see, but there is less than half an inch of clearance after the panel goes on.
