An older C0-stepping Core i7-920 processor produces a great amount of heat when overclocked, which is perfect for testing the ventilation of today’s cases.
Asus’ P6T keeps the processor stable at high temperatures and current loads.
Still on loan for our previous CrossFire scaling article, Diamond’s Radeon HD 5870 is the largest card in this particular lab for checking case fit and card ventilation.
Rosewill’s Fort 120 air cooler is large enough to expose any potential mounting-space issues, noisy enough at full speed to reveal a case’s noise-isolation capability, and powerful enough to keep our overclocked CPU well below its thermal limits.
An 80 PLUS Gold rating and modular design make OCZ’s Z1000, the most efficient 1,000W power supply we could find, the perfect unit for high-end case reviews.
|Prime 95 v25.8||64-bit executable, Small FFTs, seven threads|
|FurMark 1.6.5||Windowed Mode, 1280x1024, 8X AA, Stability Test Minimum and maximum temperature|
|RealTemp 3.40||Highest-core reading at full CPU load (60 minutes) Highest core reading at 30 minutes idle|
|Galaxy CM-140 SPL Meter||Tested at 1/4m, corrected to 1m (-12db), dBA weighting|
In order to create the maximum possible thermal load from our hardware, we dedicated a single CPU thread to FurMark and the remaining seven threads to Prime95 simultaneously, measuring the component temperatures after warming the system for one hour.
Galaxy’s low-cost CM-140 SPL meter takes care of our audio-testing needs, though its 32dB minimum rating forces us to check audio levels at a .25m reduced distance. All readings were taken at an industry-standard 1m distance (-12dB).
