At idle, the HD 4870 configuration produced a very low 21 dBA@1m with the stock fans set to 7V/10V (low). The system was well cooled. No noticeable vibration passed from the hard drive to the case.

On load, the GPU fan speed peaked at 1600 RPM, causing a 3 dB increase, which is excellent for this test system. While not quiet, the HD 4870 stock cooler is among the better sounding blower fan models, so the acoustic profile consisted mostly of a soft, hissing sound, and much of the clicking emitted by the system fans was muted. Temperature increases were modest, 14°C for the CPU, 21°C for the GPU, and 10°C for the Southbridge chip directly beside the graphics card. Increasing the fan speed to 9V/11V (low) helped somewhat, at a modest noise cost.



Our HD 4870 test system measured 21 dBA@1m at idle and 25~26 dBA@1m at full load.

In our single graphics card configuration, the FT02 produced the same amount of noise as the Raven RV03, but the system components were slightly cooler, the hard drive in particular. Recent offerings from Antec, the P280 and Solo II, couldn't compete with either of the SilverStone cases.

A Note on Thermal/Acoustic Testing of Cases

For readers concerned that using a many-generations old video card makes our testing inadequate, let us assure you: A case does not "know" or "care" whether the components installed in it are old or new. The things that matter are thermal and noise characteristics. The TDP (Thermal Design Power) of the HD 4870 is 160W. This is fairly comparable with current high performance video cards. To put it in context, a current HD 7870 is rated at 175W, and a HD 7850 is rated at 130W. A GeForce GTX 560 is rated at 150W, and a 560 Ti at 170W.

Long time readers are aware that this video card (and almost all the components used for this case review) is the same one used at SPCR for high end cases for several years. This is one of the key operating principals of SPCR: Keep test components as consistent as possible so that the results of a new case review can be compared fairly with one that's even several years old. It ensures that our test database has a long usable life.
