Awhile back, some questions arose about the consistency of the Akasa Silver Mountain HSF distributed by Lapicon a division of Akasa.

The questions were raised by Kyle Bennett of [H]ard|OCP fame and rightfully so. The Silver Mountain looks like the original Kanie Hedgehog dressed in Silver. Being a Hog lover from the beginning (the heatsink version), Kyle’s statement concerning the inconsistency of the manufacturing process of the original Hog was well documented by the reports of wildly fluctuating temperatures between different Hedgehogs. We personally experienced the phenomena ourselves.

With this in mind, Adrian Young of Lapicon, contacted me and informed me that he was sending 10 Silver Mountains to Kyle for analysis. Understanding that my methods of testing were quite different than Kyle’s, would I be willing to test 10 Silver Mountains. This study is the end result.

We decided to run two complete tests on each of the Silver Mountains, one test on System #1 and the second test on System #2; we wanted to see if a hotter running CPU would affect the outcome of our study.

Test system “Number 1” is comprised of a high performance well cooled Athlon 1.2 GHz 266 FSB AXIA CPU running at a VCore voltage of 1.75, on an Abit KT7A-Raid motherboard housed in a closed aluminum Lian-Li PC-60 mid-tower case.

Test system “Number 2” is comprised of an Athlon 1.4 GHz CPU running at a VCore voltage of 1.85, on an Epox 8K7A+ motherboard housed in a closed aluminum Cooler Master ATC-201 mid-tower case.

All the standard items were included, in both computers that you would expect to find in high-end fully loaded systems.

The procedures for this study will follow our normal pattern and our tests are conducted under real world conditions, but this time, in two different closed aluminum cases, both of which are cooling friendly. We use a mix of software that best reflects the usage patterns of the majority of computers used day in and day out.

We run our tests for a consecutive four day period and to record temperatures, we employ Award Bios, Via Hardware Monitor and a heat sensor applied next to the CPU’s core from the DigitalDoc5. The room temperature of 74 degrees Fahrenheit or 23 degrees Celsius is maintained +/- four tenths of a degree.

The mix of software as always consisted of business and accounting applications, a varied combination of utilities, AutoCAD Lite, graphic intensive packages, 3D games, surfing the net and burning our favorite CD’s.

Fifty readings per day are taken in each test for a total of 200 separate readings, with the high and low readings for each day removed leaving a total 192 readings. The entire procedure was repeated, once on each system for each of the 10 Silver Mountains.

As the purpose of this study is to analyze the 10 different Silver Mountains and not to review them, we will list the Silver Mountains 1 thru 10 giving you the average attained temperature of numbers 1 thru 10 on each system. Our complete review of the Akasa Silver Mountain can be seen at

Test Results and Conclusion

While we did find differences when we inspected the Silver Mountains under a high-powered magnifying glass, the end result, as to performance was so small as to be un-important. See for yourselves!!!

As you can see, on “System #1” the spread in Fahrenheit is only 4 degrees and the spread in Celsius is only 2.2 degrees. The spread in “System #2” in Fahrenheit is only 3 degrees and in Celsius it is only 1.7 degrees.

Our test show the high degree of consistency found in the Akasa Silver Mountain and proof that the Silver plating and most likely, tight quality control, pays dividends. The Silver Mountain is one of the world’s best and it’s pretty too!!!!
