TEST RESULTS: Asus EAH6850 DirectCU

To simulate a more demanding gaming 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.

*set as low as possible to maintain a GPU temperature of ~90°C.
CPU fan set to 9V.
Ambient temperature: 22°C.

We started testing our HD 6850 configuration with the stock fans set to 7V, a level that surprisingly allowed our system to be tweaked to run adequately cooled with a noise level of just 20 dBA@1m both idle and at load. Taking the GPU fan off automatic control, we lowered it until the core temperature reached about 90°C. To our amazement, we were able to bring the fan speed all the way down to the 1670 RPM, the minimum allowed. Turning up the case fans to 9V resulted in a 3°C improvement in CPU temperature but the rest of the system was unaffected.


Our EAH6850 test system on load measured 23 dBA@1m with the stock fans at 9V.

*PC-V354 tested with Noctua NH-C12P heatsink rather than the NH-U12P due to incompatibility.
**FT03 tested with a Seasonic X-650 power supply rather than the Cooler Master M700 due to incompatibility.
CPU fan set to 9V.
Ambient temperature: 22°C.

The Define Mini really shone with a more powerful GPU; our HD 6850 configuration was 2 dB quieter than the SilverStone TJ08-E. It wasn't a clear-cut victory, as the TJ08-E's 180 mm fan gave it a significant advantage in both CPU and hard drive cooling. Adding a second fan at the top of the Define Mini might turn the tide but the TJ08-E also has a spare exhaust fan placement.
