Corsair Obsidian 900D Case Review: Think Big, That's Only HALF as Largeby Dustin Sklavos on April 16, 2013 11:00 AM EST
For testing full ATX cases, we use the following standardized testbed in stock and overclocked configurations to get a feel for how well the case handles heat and noise.
|ATX Test Configuration|
Intel Core i7-2700K
(95W TDP, tested at stock speed and overclocked to 4.3GHz @ 1.38V)
ASUS GeForce GTX 560 Ti DCII TOP
(tested at stock speed and overclocked to 1GHz/overvolted to 1.13V)
2x NVIDIA GeForce GTX 580 in SLI
(full fat testing only)
|Memory||2x2GB Crucial Ballistix Smart Tracer DDR3-1600|
Kingston SSDNow V+ 100 64GB SSD
Samsung 5.25" BD-ROM/DVDRW Drive
3x HGST DeskStar 3TB 7200-RPM HDD
|CPU Cooler||Cooler Master Hyper 212 Evo with Cooler Master ThermalFusion 400|
|Power Supply||SilverStone Strider Plus 1000W 80 Plus Silver|
Each case is tested in a stock configuration and an overclocked configuration that generates substantially more heat (and thus may produce more noise). The system is powered on and left idle for fifteen minutes, the thermal and acoustic results recorded, and then stressed by running seven threads in Prime95 (in-place large FFTs) on the CPU and OC Scanner (maximum load) on the GPU. At the end of fiteen minutes, thermal and acoustic results are recorded. This is done for the stock settings and for the overclock, and if the enclosure has a fan controller, these tests are repeated for each setting. Ambient temperature is also measured after the fifteen idle minutes but before the stress test and used to calculate the final reported results.
For the "full fat" testbed, the GTX 560 Ti is swapped out for a pair of GTX 580s, and three hard disks are added to fill out the case.
