At idle our HD 4870 configuration inside the P280 produced a fairly low 21 dBA@1m. The CPU and hard drive rested comfortable with temperatures just below 30°C, while the graphics card settled at 76°C with its fan spinning under 900 RPM. On load, the GPU fan speed approached 2000 RPM causing a 6 dB increase in noise, but as the HD 4870 stock cooler is among the better sounding blower fan models, much of the noise consisted of a soft, bearable hissing type sound. Temperature increases were modest, 16°C for the CPU, 11°C for the GPU, and just 6°C for the Southbridge chip sitting directly beside the graphics card fan.



Our HD 4870 test system measured 21 dBA@1m when idle and 27 dBA@1m on load.

In our single graphics card configuration, the P280 was about on par with the Solo II, producing slightly higher GPU and Southbridge temperatures but at a slightly lower noise level. It stacked up well against the Fractal Define R2. The R2, with a side fan blowing over the video card required a lower GPU fan speed, but the noise level wasn't much better Also note that the side fan is not included in retail models of the R2/R3.
