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 after a 15-minute stint of the intensive Prime95 stress test is applied to all cores. To get an idea of GPU cooling performance, we record GPU temperature after 15 minutes of running Aliens vs. Predator. Last but not least, we also record chassis noise by using a PCE-318 noise meter to take readings when idle and while running Aliens vs. Predator.
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 the Cougar Challenger was recorded as 21.4ºC.
The Cougar Challenger ships with just two pre-installed fans, but the 200mm intake and 120mm rear exhaust do a good job of providing a clean supply of air. Our overclocked Core i5 is kept running at comfortable temperatures under extreme load.
The 200mm front intake, combined with a mesh cover on the side fan mount, also does a good job of keeping our dual Radeon HD 7950 graphics cards running cool during a stint of Aliens vs. Predator. Out-the-box performance is good, and with many available fan mounts, it can only get better.
Cougar's provided fans aren't particularly offensive on the noise front, either. The system could be quieter when idle, but it doesn't get annoyingly loud under load.
