System Configuration:

Measurement and Analysis Tools

System temperatures were recorded with RealTemp, SpeedFan, and GPU-Z at idle and on load using Prime95 (small FFT setting) and FurMark, an OpenGL benchmarking and stability testing utility. Power consumption and noise levels were also measured.

Baseline Noise

The Phenom ships with a pair of 3-pin Spectre 120 mm fans which use fluid dynamic bearings and have a nominal speed of just 1,000 RPM. There was about a 100 RPM difference between the two samples so we tested them at an average speed of 800 RPM and their maximum of 1050 RPM.

Measuring mic positioned 1m at diagonal angle left/front of case.

At 800 RPM, the fans measured just 14~15 [email protected], low enough that there's really no need to run them any slower. At top speed, they produced only 20 [email protected], which is still fairly quiet in our books.

The quality of noise was excellent, smooth at both 800 and 1050 RPM, though the front fan had a clickiness that the rear fan lacked. However, in normal operation with the our test system turned on, it was hard to detect. There was also a slight buzzing on both samples but this was only audible when we placed our ear right up to the motor.
