Testing Methodology

For testing Micro-ATX and 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
CPU Intel Core i7-2700K
(95W TDP, tested at stock speed and overclocked to 4.3GHz @ 1.38V)
Motherboard Gigabyte GA-Z68MX-UD2H-B3
Graphics Card ASUS GeForce GTX 560 Ti DCII TOP
(tested at stock speed and overclocked to 1GHz/overvolted to 1.13V)
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Kingston SSDNow V+ 100 64GB SSD
Samsung 5.25" BD-ROM/DVDRW Drive
CPU Cooler Cooler Master Hyper 212 Evo with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Plus 750W 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.

Thank You!

Before moving on, we'd like to thank the following vendors for providing us with the hardware used in our testbed.

    But do you plug those drives into the front of your case? I plug my drives into the rear, and if I have a temp drive to transfer data to/from, then that one drive will plug into the front.

    Need better thought than this.

    Because I have no need for a full ATX board, Silverstone could do a fantastic silent case.

    Take the TJ08, widen it slightly to allow room for dampening material (and cable management), maybe a revamp to the front so that (so similar to Antec 180), look at PSU mounting (lots of silicon dampening) and my personal bug bear - will someone please include some anti vibration mountings for optical drives!

    First, simply don't install an optical drive and it will add 0dB of noise to your system. If you can't handle not having "lasers" inside your computer then realize that spinning a 16g polymer plastic disc at 10k+ RPM is going to make enough noise that any vibration transmitted to the case will be incidental.

    Remember what I said about noise levels in silent cases? This is what happens. The Ghost is able to do the best job of keeping our overclocked testbed quiet, but again the DS1 is able to handle the increased thermal load more gracefully.

    We have to keep in mind that the Silentium simply isn't designed for this usage scenario, and that's fine. But in the process, cases like the Ghost and R4 start to look like better deals. The R4 is more expensive, but the Ghost isn't.


    How is the Ghost doing the "best job", if the DS1 outperforms it in almost every single measurement?
    And how does the R4 start to look like a better deal, if it is noisier than the AZZA with higher GPU temperatures, while being more expensive?

    It seems like those conclusions were written without looking at the measurement results at all.

    Man I want that to case to come over here.

    Given how we have so many All in one watercooling solution it would be nice if you started to incorporate a small section for watercooling with the mainstream coolers. Corsair H100, H80 etc.

    I look at the picture, I read till " it's cheaper to use a single USB 3.0 port and a single USB 2.0 port by a couple of bucks" and decided that this is a $19-29 market case at best. At $99 it is a joke. My Dell workdesk PC is dead silent regardless its canny thick case. There is no reason this AZZA plastic POS to be $99 expensive.

    Seriously, dont do it. Buy a case which is not like Swiss cheese and do it yourself accurately.
    Even cheap cases will turn into sound eating monsters (especially weight-wise).
    Plus they will be completely air tight, so the air flow of the case fans will be excellent without any increase in temperature.
    Sure, getting off the side panel and back on, will be more work, but it will really eat sound like nothing and will be more than worth the 12 hours spent to get it done. I can actually run my fans on much higher speeds before I hear them and I never have issues with other noise. You wont believe how quiet my DVD drive is.

    Pre-insulated cases are placebos.

    Whilst an air-tight case would definitely be quieter, it's not an option for most people as they don't wish to replace their entire computer every day after it is damaged from excessive heat.

    If there's not fresh air coming in, your computer will gradually get hotter and hotter until something in it melts.

    A closed design case will be quieter than an open design, but even closed designs need to allow for sufficient air to flow out of and especially into the case.

    I think he meant air-tight except for the fan vents. ;)
