Testing Methodology

For testing 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.

Full ATX Test Configuration
CPU Intel Core i7-875K
(95W TDP, tested at stock speed and overclocked to 3.8GHz @ 1.38V)
Motherboard ASUS P7P55D-E Pro
Graphics Card Zotac NVIDIA GeForce GTX 580 (244W TDP)
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Kingston SSDNow V+ 100 64GB SSD
Western Digital Caviar Black 1TB SATA 6Gbps
Samsung 5.25" BD-ROM/DVDRW Drive
CPU Cooler Zalman CNPS9900 MAX with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Gold 750W 80 Plus Gold

A refresher on how we test:

Acoustic testing is standardized on a foot from the front of the case, using the Extech SL10 with an ambient noise floor of ~32dB. For reference, that's what my silent apartment measures with nothing running, testing acoustics in the dead of night (usually between 1am and 3am). A lot of us sit about a foot away from our computers, so this should be a fairly accurate representation of the kind of noise the case generates, and it's close enough to get noise levels that should register above ambient.

Thermal testing is run with the computer having idled at the desktop for fifteen minutes, and again with the computer running both Furmark (where applicable) and Prime95 (less one thread when a GPU is being used) for fifteen minutes. I've found that leaving one thread open in Prime95 allows the processor to heat up enough while making sure Furmark isn't CPU-limited. We're using the thermal diodes included with the hardware to keep everything standardized, and ambient testing temperature is always between 71F and 74F. Processor temperatures reported are the average of the CPU cores.

For more details on how we arrived at this testbed, you can check out our introductory passage in the review for the IN-WIN BUC.

Last but not least, we'd also like to thank the vendors who made our testbed possible:

Thank You!

We have some thanks in order before we press on:

  • Thank you to Crucial for providing us with the Ballistix Smart Tracer memory we used to add memory thermals to our testing.
  • Thank you to Zalman for providing us with the CNPS9900 MAX heatsink and fan unit we used.
  • Thank you to Kingston for providing us with the SSDNow V+ 100 SSD.
  • Thank you to CyberPower for providing us with the Western Digital Caviar Black hard drive, Intel Core i7-875K processor, ASUS P7P55D-E Pro motherboard, and Samsung BD-ROM/DVD+/-RW drive.
  • And thank you to SilverStone for providing us with the power supply.

    And this is pretty strange. My guess is the team at Silverstone must be a pretty unusual lot.

    Personally, I think case companies such as Li-Lian or SilverStone should stop trying to innovate in the case design; the S design is pretty well proven. Instead, they should innovate in HOW they cool it, for example, take Alienware's "active cooling" to the next level. First, add those fin things alienware did, and, instead of just having them flip up and down uselessly, have a fan connected, so when they flip up, the fan starts up...little things like that that will help idle noise while not hurting performance under load

    That kind of solution requires far more money and engineering for questionable results imo... And the S design just sucks. It may be fine for 90% of systems out there, but it's far from optimal for any enthusiast or gamer running one or more high end GPUs (each one generating more heat than an old Pentium 4). You could argue that's a GPU issue but until that market slows down we're far better off with some innovative case designs.

    Obviously this case is a miss on the GPU-cooling front... At least with the stock config, but I was speaking in general above (and with some of ST's other designs in mind). Frankly I appreciate these reviews for the usual in-depth scope most AT reviews have, but I think the performance metrics are rather worthless, specially as a way of comparison against other cases.

    I understand why it's done like this, and frankly I can't think of a fairer way of doing it... But I also can't picture any enthusiast worth his salt not making any changes whosoever to the stock cooling of a case in a DIY build, specially when we're talking $150-300 cases.

    Sometimes the smallest changes can make a huge difference, it just seems equally unfair to write off some enclosures because they lacked an extra $15 fan. Different mentality I guess... I certainly don't follow the same logic when say, buying a car, even tho I know people who would.

    The S design hits the hard drives, CPU, RAM, and Chipset, only the GPU's are left to fry, but even then, in most cases (pun not intended) there is a side fan, which hits the GPU directly, so, just add a 10 dollar fan into one of those slots and the S design is all the sudden made quite a bit better. Also, I might just like to point out, to release a fully functioning case (as in not this), extensive tests have to be done, revise, test, revise ect. In this situation, even though the upfront costs are higher, you can get a product that works into the market quicker, without the extra cost and time that it takes to test and then revise a product. (And yes, this fan control would have to be revised, but it wouldn't take nearly the same amount of time as revising a case IMHO)

    The Silverstone website does not state that a mini-ITX will fit in the case. Can you confirm or deny whether it actually does?

    Thank you
