Part 3. Test results, Conclusions
Testbed Configuration 1:
We use the S&M utility to simulate maximum thermal load of a processor, and Speedfan - to monitor temperatures. Thermal Monitor is disabled in all the tests.
Testbed Configuration 2:
We use the S&M utility to simulate maximum thermal load of a processor, and SystemGuard from Fujitsu-Siemens to monitor temperatures.

Finally, at the end of this article we publish the noise measurement results (the method of testing is described in the article Noise characteristics of coolers and the noise measurement method) as well as the efficiency/noise rating of coolers.

There seems to be no need in any comments here. Let's draw the bottom line!
Here is our verdict for today: our contenders have aced the tests, demonstrating good thermal efficiency and proving out their Hi-End status. It's rather hard to single out an absolute leader (as well as an absolute outsider). Nevertheless, the most attractive coolers in usability terms are Scythe Ninja and Zalman CNPS9500 LED - they demonstrate champion-like results, skillfully combining neat technical quality, the highest thermal efficiency, and ergonomic noise parameters.
Drum-roll. Time has come for the high tide of our shootout - awarding selected products. We have two lucky models today: Scythe Shogun and Zalman CNPS9500 LED get the Original Design award for truly original and refined technical solutions. Congratulations!
Well, we wish the leading cooler brands - Cooler Master, GlacialTech, Scythe, Thermaltake, Titan, and Zalman new successes and achievements in the noble cause of manufacturing Hi-End cooling systems! Let's hope they will gratify us with no less interesting coolers next year as well.
