Ambient temperature: 22°C.

Our test system, consisting of a Core i5-750 quad core CPU and a Radeon HD 6850 GPU, was inconspicuously quiet in its idle state, measuring 19 dBA@1m with the CPU fan at 9V and case fans at 5V. Pressing our hand directly over the hard drive area, we could feel some minor vibrations but this didn't seem to be passed onto the rest of the case — at one meter there was no audible hard drive related noise. Internal temperatures were all very good as well.

Next we put the CPU under synthetic load, producing a slight increase in noise level, probably due to the power supply fan spinning up in reaction to higher temperatures inside the unit. The Noctua NH-C12P is a fine heatsink but the CPU got too hot for our liking, shooting up to 75°C. The extra heat spread out through the rest of the case, driving up the hard drive and GPU temperatures by a moderate amount.

Adding a GPU load to the system placed a considerable additional strain on the machine. A GPU fan speed of 2100 RPM was necessary to keep the GPU at 90°C and the CPU flirted with the 80°C mark. While it got quite toasty inside, the noise level was impressive, only 2~3 dB higher than at idle. Pumping up the system fan speeds to 7V helped tremendously, cooling down the CPU by 9°C and allowing the GPU fan to slow by 400 RPM without any appreciable difference in cooling. At the cost of an extra 1~2 dB, it was a worthwhile move.

*Tested with Noctua NH-C12P heatsink rather than the NH-U12P
(due to incompatibility).
**CPU fan set to 12V rather than 9V.
Ambient temperature: 22°C.

The performance of the GD08 was so strong, it stacked up admirably against the Fractal Define Mini, the best microATX tower we've tested, an impressive feat for a desktop style case, which usually don't have as good thermal performance. Compared to the Fractal Design Node 605 we reviewed recently, there's simply no contest — the GD08 absolutely crushed it. The smaller Node 605 had great difficulty keeping our test system stable, requiring both of its fans to run at maximum speed and the video card fan to spin almost twice as fast. Even then the CPU temperature was 18°C higher and the noise level was through the roof.

Both cases use a positive pressure airflow scheme but the GD08 is considerably larger and has more fans positioned closer to the CPU area. The Grandia also has less restrictive dust filters and a ventilation port on the top of the case which is noticeably absent from the Node 605.
