TEST RESULTS: DUAL RADEON HD 4870 CONFIGURATION

Given the Raven RV05's size, it didn't seem likely that anyone would use it with a single video card, so we jumped straight into our CrossFireX test configuration.

With the machine idle and stock fans set to low, our system produced a reasonable 25 dBA@1m. The GPU fans spun at 900/1020 RPM and below, keeping the GPU core temperatures at 72/61°C. On load, the CPU, Southbridge, and GPUs all reached double-digit temperature increases and the top video card's fan doubled in speed to compensate for the additional thermal output. In this state, the system's noise level was 29 dBA@1m, which is phenomenally low for this system configuration (30 dBA@1m and below is rare).

High system fan speeds resulted in minor temperature decreases but the extra cooling didn't do much to dissipate the heat of the graphics cards. The GPUs did run cooler but the corresponding GPU fan speed reductions weren't enough to offset the added noise generated by the system fans.

We're fortunate that the HD 4870's used in our test configuration have a mostly broadband acoustic profile, sounding a lot like static at high speeds. As the stock fans have a decent sound as well, the combined noise was quite audible but not entirely unpleasant on load. When the GPU fans sped up, the pitch of the overall noise increased, which made it sound less dry and hummy.

The sonic effect of the 7200 RPM hard drive was interesting. Much of the vibration produced by hard drives is horizontal, so mounting them vertically usually takes care of the issue entirely. However, the RV05's drive mounting system has the drive physically touching a significant portion of the surrounding cage without any damping/isolation features, and the adjacent side panel is not particularly secure. As a result, when the system was idling, there was some audible vibration effects observed at close proximity and the corresponding 120 Hz tone pulsed between the 5 and 10 dB levels. In our case, it wasn't noticeable at a reasonable distance, but it could be an issue if quieter components were used.

Among the various Fortress/Raven cases we've tested, the RV05 finished behind only the FT02 in overall thermal/acoustic performance. It makes sense as the RV05's design is the most similar to the FT02, despite the smaller size. The third and fourth generation Ravens never managed to recreate the FT02's success but the RV05 comes very close.
