Without any system fans turned on and the CPU fan set to 9V, our IGP test system was exceedingly quiet when idle, measuring 16~17 dBA@1m with system temperatures hovering at about 40°C. On load with the stock fans at full speed the CPU temperature rose by 18°C while the hard drive cooled down by 9°C. A 5°C improvement was recorded when we cranked up the CPU fan to full speed.


Our HD 3300 IGP test system measured 18~19 dBA@1m both when idle and on load with the stock fans at 12V and CPU fan at 9V.

With the rest of the components turned on the clicking of the Silencio's stock fans was thankfully blended away somewhat, barely noticeable at one meter while more clearly audible at shorter distances. The acoustic profile was mainly smooth with almost no tonality except for a slight hum generated by the hard drive.

On load, our IGP test system performed similarly in to the Fractal R2/R3 and NZXT H2. Only a few degrees in hard drive and Southbridge temperature and less than 1 dB of noise separates the three.
