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
3x HGST 3TB 7200-RPM HDD
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.

    A useful review is one that compares an item against another using metrics that are important to the readers. Without a standard set of system components used in every review for every case in the comparison, a review turns into just another "I bought it, it works, I like it" write-up that other hardware sites like to pass off as "reviews."

    A solution to this could be Anandtech developing and using heating elements configured to produce similar amounts of heat and noise in similar locations to a standard ATX / mATX system. Then these elements could be adjusted to produce standard levels of heat output (65/77/95W) enthusiast heat output (130W/150W) and overclocked (200W+).

    Multiples of these heating elements could be placed in the larger cases to simulate high heat GPUs and determine exactly how much thermal capacity a given case has for such a scenario.

    But... custom fabrication, testing, and implementation of equipment such as this would be very spendy initially and the payoff questionable and unnecessary if the products in question fall into the disposable income category for your readership.

    The metrics have to be relevant, though.

    It's reasonable to assume people are not buying big towers because they need to fill their empty rooms, but because they have components that require a big case.
    And you can't tell me that one of the - if not THE - premier tech sites on the web is not able to get three different sizes of mainboards to their case reviewer and a bunch of toasty GPUs to Trip-SLI. They can go on eBay and buy an ageing Nehalem CPU and a set of GTX 285s for all I care.

    Testing this monster of a case with 3 HDDs, an mATX board and a little 560 makes no sense, because the only valid conclusion can be that it is too big.

    The problem at this point is that if I switch up to a full ATX board now, it destroys the comparative data I've accumulated over the past year. I've been working on a third, "full fat" level using this board, but ironically the board's second PCIe x16 slot isn't working and so I can't bump up testing parameters until I've sorted that out.

    Your case reviews are outstanding minus one thing:

    You should really consider using an ATX sized motherboard when reviewing full sized cases. I've noticed on previous reviews the habit of using small motherboards in larger cases, and it really doesn't give me a good feel for its target component size.

    ATX, Micro-ATX and mini-ITX boards should be used according to the size of the case being reviewed.
  • Hrel - Wednesday, February 20, 2013 - link

    Agreed. I've said this on other case reviews. Changing the size of the mobo but keeping the same chipset shouldn't affect any of the tests. There's really no reason not to. Unless you're buying a mimi-ATX case or smaller you are probably using a Full ATX motherboard, or larger. I stay with ATX for the expansion slots. Currently still running an old Nvidia 650 SLI chipset, but it has a USB 3.0 controller and SATA 6GBPS ports because of the expansion slots available in the motherboard. That computer is nearing it's end of life but with the SSD in it the CPU is actually the slowest part. Still run everything I do great and I have no intention of upgrading until it can't.

    Lots of people have been saying this over and over in every review like this at this site. I agree, it makes little sense to test the case with a small motherboard that most of us would never in a million years put in this case.

    But the reviewers are obstinate. They want you to be able to compare the reference system from a microATX case to a ATX XL case and see what the benchmarks say is the best case.

    For better or worse.

    I hate that methodology.

    People aren't choosing between mATX and XL-ATX.

    Car reviewers figured that out a long time ago. No sense pitting a Corvette against an Escalade and a Ford Fusion. Nobody will decide between these based on trunk size or fuel economy.

    There are fringe cases out there for sure, but the vast majority buys cases based on what they can do with them. In the case of a full towers that's stuffing it full of chips.
    If you have an mATX board, you get an mATX case. Chances are you bought it for the size or the prize.
    Either way, you ain't considering the Fractal Define XL R2...
  • Dustin Sklavos - Thursday, February 21, 2013 - link

    The reason I made this call and stand by it:

    What do you lose by going with an mATX board over a standard ATX board?
  • haplo602 - Thursday, February 21, 2013 - link

    It's not ATX vs mATX. This is an XL-ATX/E-ATX capable case, so some people will lose PCI-E slots and some even a CPU socket (my case) which is show stopper.

    There are plenty of cases that can fit an mATX board. It's the other end of the spectrum that's starved.
  • tim851 - Thursday, February 21, 2013 - link

    Ask yourself this: why is anybody choosing a full tower? An mATX board, single GPU and three hard disks fit into a Silverstone TJ08. Do you think there are people undecided between a TJ08 and a Define XL waiting for a comparative review?
