TEST RESULTS: Asus EAH6850 DirectCU

To simulate a more demanding, gaming type of system, our second test configuration uses an HD 6850 graphics card from Asus. The 6850 uses about 100W more than the 5450, creating a hotter, more stressful environment.

When idle, the addition of the EAH6850 had only a small acoustic impact, increasing the noise level by 1~2 dB and imbuing the system with a slightly harsher sound. On load, after toying around with the fan speed we found that low/10V gave us the best balance of performance-to-noise. At 9V we had to run the GPU fan a bit faster so there was no noise advantage, but the resulting CPU temperature was 4°C higher. 12V allowed us to drop to slow the GPU fan by ~300 RPM, but exchanging an extra 4 dB for marginal CPU and hard drive cooling improvements was an unbalanced trade.

It should be noted that SilverStone recommends using a graphics card with a fan that blows air out the back, following the same airflow path as the case's intake fan while our test card uses a downblowing heatsink with the exhaust coming off both sides. This type of cooler may perform better with the TJ08-E's design.


Our EAH6850 test system on load measured 24~25 dBA@1m.

*Due to compatibility issues, the FT03 was tested with a Seasonic X-650 power supply (vs. Cooler Master M700) and the PC-V354 with a Noctua NH-C12P heatsink (vs. NH-U12P).
CPU fan set to 9V.
Ambient temperature: 22°C.

The TJ08-E ekes out a slim but clear victory over the FT03 and PC-V354. Its overall thermal performance was superior, and it noise level was a tad lower as well.
