Summary: This cooler has the same cooling efficiency of my OEM AMD FX 6300 cooler but much quieter. Make sure you have a wide case to handle this cooler, check out many install videos and research your MOBO for compatibility. I had to mount my side case fan on the outside of the case otherwise, the cooler would contact the fan. My case is 8 1/2 wide.
Summary: I buy these on sale or when I build an new box. If you go air there is no better CPU cooler for the price. Okay the cons. Be prepared to figure out the holding mechanism. I have built 5 plus boxes with these over the years and still have some trial and error of which way the X goes under the fins. Do not screw down into mobo stand-offs until you are sure. It will save you some time. I am always a little worried about the size of the whole on the bac of the mobo.
Pros: Relatively quiet works well to cool cpu
Cons: A bit tall do not fit in narrow cases resistor paranoia
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.
