Our IGP test system was very quiet at idle, measuring 19 dBA@1m with the CPU fan at 9V and the system fans at 7V. On load, the CPU and Southbridge temperatures rose by 24°C and 6°C respectively while the hard drive remained at a cool 31°C; There was no difference in noise level (the power supply fan might have ramped up but was drowned out by the rest of the system). Speeding up the CPU fan to 12V lowered the CPU temperature by 2°C and increased the noise level to 20 dBA@1m which is the around the upper limit with which we try to restrict cases to using our IGP configuration.


Our HD 3300 IGP test system measured 20 dBA@1m on load with the stock fans at 7V and CPU fan at 12V.

Though our SPL measurements were low, we could detect a steady, slightly annoying, low pitched, electrical-sounding hum emitted by the system, likely a result of a hard drive vibration being passed onto the rest of the case. Even though we took steps to prevent this by adding styrofoam padding, it was still evident. The sound actually showed up in the spectrum analysis as a tonal peak at ~120 Hz which corresponds to the 7200 RPM speed of the hard drive.

As our IGP test system is not particularly taxing, the Silencio 450 turned in results similar to other "quiet" cases we've tested in the past, performing very similarly to Silencio 550 which shares much of the same DNA.
