The Akasa Silver Mountain 2Q falls into the category of "lower noise cooling" since its' fan produces less less than 50 dB. With that in mind, the middle of the road performance the heatsink is capable of can be taken in a slightly better light.

With a rise above ambient temperature of around 52.8 degrees Celsius on our 100W synthetic test system, the heatsink offers capable cooling for the Athlon processor. I think a faster fan would be beneficial if you were looking to do some overclocking, but with CPU speeds reaching 3GHz on the Socket A platform there really isn't as much of a need as there used to be.

In any case, a couple points about the Akasa Silver Mountain 2Q. 1) that matt black wire fan grill looks really nice, and still protects the fingers from damage. 2) The silver coating will prevent the copper from oxidizing over time, and depending on how thick the plating is, fill in some of the small voids between the fins and base. Lastly, while the general finish of the unit we tested was excellent, the base was domed out a little, and could do with some slight lapping for optimal results.

You can easily check this on your Silver Mountain heatsink (or any other for that matter) by holding the edge of a metal ruler to the base of the heatsink in front of a light. As long as your ruler is straight you should be able to clearly see how warped, domed, wavy, or flat the base actually is where the processor makes contact.
