The addition of a second HD 4870 had only a minor acoustic effect on our test system at idle and system temperatures remained mostly the same except for the GPU which warmed up by 11°C (luckily this didn't cause a significant increase in fan speed). At one meter's distance, the noise level was a reasonable 23 dBA. Pushed under load, the system exceeded 30 dBA@1m, completely drowning out the top fan so we cranked it to maximum and tried varying the bottom fan speeds.

As it turns, out leaving the floor fans at 9V/low was the sweet spot, giving us the best blend of noise and performance. Further fan speed increases helped the GPU somewhat, but the increase in noise from the system fans canceled out any savings from the minor reductions in GPU fan speeds. Southbridge cooling was the only thing that really improved. In this fan configuration, the noise level was measured at 31~32 dBA@1m, which, while loud by our standards, is quite good for our dual HD 4870 configuration.



Our HD 4870 CrossFireX test system measured 23 dBA@1m when idle and 31~32 dBA@1m under load.

The RV03's supremacy vanished with our CrossFire test system as it performed similarly to the massive Cosmos II. It did manage to cool the CPU by an extra 5°C but gave up the same in hard drive temperature due to the lack of front fans in the stock fan configuration. The champion remains the In Win Dragon Rider as its brute force cooling strategy was simply too overwhelming. Its stock fans include a massive 22 cm model blowing over the video card and a 12 cm variant blowing on the back of the CPU. At least the latter can be replicated by adding a fan on the Raven's right side panel.

Note: due to changes in our test system, results from previous cases like the Raven RV02 and Fortress FT02 were omitted. As the core designs are so similar we believe their performance would be comparable to the RV03.
