NZXT H2 Cooling Performance

NZXT H2 Cooling Performance

To give the cases that we review a good workout, we updated our test kit to include an ATI Radeon HD 5870 2GB Eyefinity 6 graphics card and an Intel Core i7-870 CPU, which has been overclocked from 2.93GHz to 3.4GHz using a vcore of 1.305V and a CPU PLL of 1.9V. While this is a modest overclock, our test kit will spend most of its life under high load, so pushing it to within an inch of its life isn't in anybody's interests. More importantly, some poorer-performing cases top a CPU temperature of 80°C, so even this overclock will prove to be too much for some cases.

The CPU is cooled by a Gelid Tranquillo CPU cooler with a Noctua NF-S12B ULN 120mm fan. The NF-S12B ULN is a low-airflow fan, so it will highlight cases with poor cooling for the CPU. We also locked the fan speed on the graphics card to 30 per cent to prevent the automatic speed control interfering with the results, making them inconsistent. After some experimentation, 30 per cent proved to be fast enough to keep the graphics card cool enough in poorly performing cases, while giving better cases the chance to shine.

We recorded the temperature of the CPU using RealTemp, noting the temperature of the hottest core, and used GPU-Z to log the temperature of the graphics card. Having recorded the ambient temperature in front of the main air intake of each case, we were then able to calculate the delta T - the difference between the ambient temperature of our lab and the temperature of the hardware.

As we don't test in a temperature-controlled lab, this allows for small changes in ambient air temperature, which renders absolute temperature measurements of the hardware useless. To load the system, we used a combination of the Canyon Flight benchmark in 3DMark06 and the smallfft test in Prime 95. We looped each test for a minimum of 30 minutes, or until the temperatures plateaued, and recorded the highest temperature in the log files. The combined test represents a worst-case scenario, with both the CPU and graphics card under sustained high load.
