Our Z77 test platform consists of an ASUS Sabertooth motherboard, an Intel Core i5-3570K processor overclocked to a modest 4.4GHz, an Arctic Cooling Freezer 13 cooler, 8GB of high-performance G.Skill Ripjaws-X memory and two factory-overclocked Sapphire Radeon HD 7950 OC graphics cards in a CrossFireX configuration.

To find out how well the chassis can cool this particular setup, we record the CPU temperature during a 15-minute stint of the Prime95 small-FFT stress test. In order to provide a stabilised reading we then calculate an average temperature across all cores from the last five minutes of testing.

To get an idea of GPU cooling performance, we then record the highest GPU temperature after 15 minutes of running Aliens vs. Predator with maximum image-quality settings at 1080p.

All chassis are tested only with the standard manufacturer-supplied fans (any/all of which are set to 'silent' in the Asus BIOS or low-speed using a fan controller if present), and to take into account the fluctuating ambient temperature, our graphs depict both actual and delta temperature - the latter is the actual CPU/GPU temperature minus the ambient. For the record, room temperature while testing today's chassis was recorded as 17.6ÂșC.

Readers should note that chassis noise is usually measured by using a PCE-318 noise meter. Said meter has developed a fault, so we'll provide general noise observations for the time being and will update the review with precise measurements once our noise meter has been repaired/replaced.
