Without any system fans, our IGP test system was very quiet at 16~17 dBA@1m depending on whether the computer was idle or on load. When stressed, it struggled to keep the processor cool though as the CPU temperature came close to 70°C. After turning on the case's stock fans at the lowest fan controller setting, the CPU, Southbridge, and hard drive temperatures decreased by 11°C, 8°C, and 5°C respectively, well worth the extra 1 dB in noise. Running the CPU fan at maximum gave us an additional 5°C improvement, but only for the CPU.


Our IGP test system on load measured 18 dBA@1m with the CPU fan set to 9V and the system fans set on low.

On their own, the H2's stock fans on low measure 14~15 dBA@1m. Adding a 7200 RPM hard drive, a Nexus 120 mm fan at 9V cooling the CPU heatsink, and a power supply fan increased the noise level to 18 dBA@1m on load. As the extra fans were fairly smooth and quiet, the acoustic character didn't change much save for a slight hum emanating from the hard drive.

On load, our H2 IGP test system beat out other quiet cases like the Fractal Define R2 and Antec P183, posting similar temperatures but with a slightly lower noise level. The H2's lack of airflow doesn't seem hurt it too much in this situation; perhaps the power draw and heat isn't enough?
