TEST RESULTS: AMD Radeon HD 5450

Our first test configuration features a low power passively cooled graphics card, a Radeon HD 5450. Our test configuration only gives us temperature data on the CPU and hard drive(s), so the HD 5450 gives us an extra data point from a different location within the case.

Vibration effects were noticeable.

The PS07, like the TJ08-E, is susceptable to noise from hard drive vibration. We could feel the case shaking, and placing pressure on the top of the case helped somewhat. With a weight pressing down on it, the overall SPL did not change, but our acoustic analysis picked up a substantial reduction in the peak at ~90 Hz, the frequency corresponding to the 5400 RPM rotational speed of the Samsung EcoGreen hard drive used in our test configuration.

Without any assistance from the case fans, our test system heated up considerably under load, with the CPU temperature hitting 84°C. Running the fans at just 7V resulted in a substantial improvement, chilling down the CPU and GPU by 12°C and 9°C respectively. The system was fairly quiet, emitting just 19~20 dBA@1m. At 9V, the cooling improved by an additional 4~5C at the cost of an additional 1~2 dB.


Our HD 5450 test system on load measured 19~20 dBA@1m with stock fans at 7V.

*PC-V354 tested with Noctua NH-C12P heatsink rather than the NH-U12P due to incompatibility.
CPU fan set to 9V.
Ambient temperature: 22°C.

In our HD 5450 test configuration, the Precision PS07 was noticeably inferior to the Temjin TJ08-E, despite sharing much of the same design. The PS07 temperatures were 9~12°C higher, while also a bit noisier. As only major change was the intake fan design, it's safe to say that the TJ08-E's 18 cm fan and its more direct fresh air path is superior to the PS07's dual 12 cm models drawing air from vents around the edge of the front bezel. The PS07 also performed poorly compared to the Fractal Define Mini and Lian Li PC-V354, both fairly popular microATX models.
