Our Test System
Basic Idea and Test Setup
To compare results as comprehensively as possible, and on an equal basis, we resurrected an older test platform that admirably simulates CPU power dissipation between 90 and 140 W.
|CPU||AMD Athlon 64 FX-62 (Windsor)2.8 GHz, Dual-Core, 2 x 1 MB L2 Cache, Socket AM2, 125 W TDP||@ 2.2 GHz, 89 W TDP@ 2.8 GHz, 125 W TDP@ 3.0 GHz, 140 W TDP|
|Motherboard||MSI K9A2 Platinum, 790FX Chipset, Socket AM2/AM2+|
|RAM||2 x 2 GB DDR2-800|
|Cooler 1||Original AMD Boxed Cooler for Athlon 64 FX-62|
|Cooler 2||Xigmatek Aegir High-Performance Tower Cooler with 12 cm Fan|
Using Xigmatek's Aegir, we tested the various power levels and cooling results for each installation option. The cooler is large enough to cool even the 140 W of an old overloaded FX processor. Although installation proves more challenging that the smaller, louder boxed cooler provided by AMD, most folks only need to do this once, making the effort invested worthwhile. We took our measurements in an environment kept at a constant 22°C via climate control.

We conducted most of the tests with this high-performance cooler because tower-coolers are currently the most popular built-in coolers. There’s an extra chapter on so-called down blowers.
