Summary: I had bought a FX-8320 along with an Asus M5A99X Evo Rev2.0 motherboard. Turns out that the default heatsink provided with the AMD processor is quite loud, bad and my CPU would run at 43-45 degrees idle. Now, I love my PC sessions quiet and the default heatsink was a nightmare. Bought this for about 30$ and it's relatively easy to install. My CPU is now idle at 29-31 degrees and in games I get to about 45 degrees.
Summary: Would buy again for sure. Keeps the CPU quite low. I think this build it's floating around 28C under load which is fairly good. These heat pipe HS/Fan's are getting taller and taller so beware if you have a smaller case.
Summary: Over the years through 4 PC builds I have gotten 4 of these granted 3 of them were the older model but no difference in temps pretty much the same design. By far one of the best air coolers on market I run 4.5ghz on i5- and i7 CPU's with temps under 50C at full load.
Summary: I can't really think of a con for this product, except its large. Which you pretty well know when you purchase it. For the price, its a great quiet air cooler. Especially for mid level overclocks.
Pros: Easy to install., Comes with extra fan clips and rubber noise dampers for a second 120mm., Quiet.
Summary: Easy to install in minutes, had to install the fan in a "pull" position in order to have sufficient room for my Hyper Beast Ram. Comes with an extra fan clip, so you could have 2 fans cooling the unit, can easily adjust the fan clip in order to clear ram on the right side, I just went with one fan. A great cheap alternative until I get my custom loop built.
Pros: Easy Installation, Easily add a 2nd fan, Price
