Testing Methodology

Part of the reason we took so long in getting new case reviews up on the site is because we decided to go back and revise our case testing procedures. Moving forward we're standardizing our testing methodology in a way that will hopefully feel more concrete and useful than our previous reviews did. I'm going to take the opportunity to break down how things are going to work for this and future reviews, but note that these procedures aren't set in stone. Anand stressed to me in conversation that one of our greatest assets is essentially the mountain of free feedback we get from people who comment on our reviews, and I agree with him. We pride ourselves on being fairly agile and adaptable to the needs of our readership, so if you feel there's something we can change and it's feasible, rest assured that we do listen and will at the very least take it into consideration.

First, we've standardized on two testbeds: a Mini-ITX testbed that's low-powered and doesn't generate too much heat, but isn't too miserly either, and a full ATX testbed that's indicative of the high-end of what most of you are running. Since this review uses our Mini-ITX bed, I'll save discussing the full ATX one for that review. The essential thinking here is that a Mini-ITX board can be used for Micro-ATX builds like this one without sacrificing much (we're not testing multi-GPU scenarios for cases this small since they're seldom designed for it), but we still use a processor that produces enough heat to merit thermal testing. Before I go any further, it may be prudent to just lay out the hardware we're testing with:

Mini-ITX/Micro-ATX Test Configuration
CPU Intel Core i3-530 (73W TDP)
Motherboard Zotac H55ITX-WiFi
Graphics Card Intel HD Graphics (IGP)
Zotac NVIDIA GeForce GTX 580 (244W TDP)
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Slimline DVD+/-RW Drive
Kingston SSDNow V+ 100 64GB SSD
Western Digital Caviar Black 1TB SATA 6Gbps
CPU Cooler Zalman CNPS8000A with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Gold 750W 80 Plus Gold

The Zotac motherboard is included as one of the most fully-featured Mini-ITX boards available, and it works with the Core i3-530 we had on hand. That i3-530 is also fairly typical of what to expect in smaller builds. From there, the Crucial Ballistix Smart Tracer memory has a unique feature particularly suited to our needs: it includes thermal diodes that can tell you how hot the memory is running. The SSD is used to gauge how easily a 2.5" drive is installed and to provide a stable baseline, while the Caviar Black gauges how easily a 3.5" drive can be installed and gives us a secondary reference point for drive temperatures. The Zalman cooler is quiet, low-profile, and effective, giving us an alternative to the Intel stock cooler. And finally, SilverStone's power supply is modular, small, and efficient, making it ideal for case testing.

Of course, the GeForce GTX 580 is going to raise some eyebrows. In this instance, we wanted a video card for case testing that would push thermals without overpowering acoustics. Not all cases we test with are going to support it, but enough are to warrant its inclusion. As a result, Mini-ITX and Micro-ATX systems are tested in two configurations: with and without dedicated graphics.

Moving on, 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 a silent apartment 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.

Finally, 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.

Thank You!

We do have some thanks in order before we press on, though:

    Actually, it's 140€
    Which is still as much as STC cost, and much less case, but - it looks sexy, runs on 120mm fans and allows a very clean build.
    Some people pay more for a certain piece of furniture, others for a certain car...For me, it's something desirable, mixed with a use, and thus I see no reason not to pay a price that the market bares - the first batch of these was sold out pretty quickly, so the price obviously isn't too high.

    I like Silverstone's rotated motherboard designs. I like the tall and shallow design. If I were looking for a micro-ATX case this one would be contender. A case with full or extended ATX support and similar tall and shallow rotated motherboard design would definetly make the shortlist for my next case. At the moment this is my favourite:

    Though to get *exactly* what I want I'll probably have to build my own case.

    Give me this case in an e-ATX size and we'd have an absolute winner.

    I think this pretty much says it about Silverstone, from the article:

    "He was upset because he felt like I gave the GD04 short shrift for griping about the noise levels, citing that once a fan controller is installed the case has exceptional thermal characteristics while being remarkably quiet. "

    Man-up, Silverstone, don't whine and cry when someone says your case design is loud, and say it's the fault of the end user for not using a fan controller and turning down the fan speed. What if the components used NEED more fan speed? Idiot.

    I have 3 Silverstone products. One is a PSU bought back when they were making their name and made some outstanding units, the thing is still powering a relative's machine today. The second is a high-end 1200W beast that has worked well enough, but had to be sent in for warranty because of a defect when I received it.

    I had bought that particular PSU by reputation alone, and it's how I learned to never buy one by reputation - after sending it back I began to read articles about it. Turned out the issue I sent it back for had been documented in reviews many months before I bought my unit!! On top of that, instead of the unit performing at the top of the tests, it barely squeaked by some of them; it just wasn't up to the standards I expected from Silverstone.

    The warranty service department snow-jobbed me very well. After being told that they were aware of the problem and had fixed it on their assembly lines, I requested a unit from that batch, What I got back was the same unit. When I called them, the word was "Oh, well, we don't have any of those." Okay, so, you've fixed the problem but you don't have any of the units with the problem fixed? Why didn't you tell me that when I requested a new PSU?

    The other product I have is a case. It's a nice enough case, and has some features I like, and some I don't. Remember the brief flirtation with BTX? It's a BTX case One of the things it came with was a plastic shroud to help air move from the front of the case across the CPU to the back. Unfortunately, the shroud wouldn't work with any CPU that needed enough cooling that the shroud would be a benefit to, because it wouldn't fit around anything but a small stock cooler. It was essentially useless, and very fragile. The worst part though is that the case has started to corrode on the inside, on some of the steel edges. Not badly, but I have an Antec case twice as old that shows no sign of corrosion at all.

    So, Silverstone is 1/3 for me, and the time I really needed them they failed. Well, I didn't believe they failed so bad that I refused to use the PSU, and it hasn't given me any trouble in 2 1/2 years, to be fair, but I'm not likely to buy anything else from them either. They are going to have to do something marvelous for me to change my mind.

    This case certainly isn't it for me.

    SPCR reviewed this case too recently if you're looking for a second opinion Unfortunately they did NOT give it high marks for noise or cooling, apparently making the case this small meant using awkward fan placements that hurt the cooling and added noise.

    If you have the space for them, the regular ATX Raven RV02 / Fortress FT02 from SiverStone do offer excellent cooling with very low noise, and are about the best you can do for quiet air cooling of a gaming system.

    Or is it just me?

    That is the EXACT thoughts I had when I saw it at a reseller evening at the end of last year. This is a great little case, and I am looking to build a gaming machine around it using my two 5870's and either Bulldozer or a 2600K (depending on what is better once bulldozer comes out, and what motherboards are available). The Asus P8P67M-Pro has the perfect PCI-e slot placement for this case, however...:D

    I don't know if I am typical of the readership here at Anandtech, but I have been consistently reading reviews here since 2003.

    I like the new case reviewing process. I sort of wish there were more pictures of the system at various stages of being built, but that's what the video is for, I suppose. The testing methodology with the uATX/MiniITX and full ATX systems is also very welcome. I am curious about the shape of the room the acoustics are measured in, and the placement of the case in that room. Maybe this is nit-picking, but for example: my computer isn't terribly loud (I don't have any numbers to back this up) but depending on where I place it and my desk it can sound much louder or quieter. Right now, I have a corner desk and the case sits along one wall, with exhaust fans blowing back into the corner (with about 4 feet of space between the fans and the wall). This arrangement makes it sound louder than other places I've had it because the sound is reverberating off the corner and toward one ear specifically.
    Since the acoustic readings for reviews are taken from one foot in front of the computer, I am curious if it is near a corner, or if the room is carpeted, etc.

    I liked this review and it helped me to decide that this case is not the case for me. When I first saw the picture I thought, "Ooh! Pretty!" and continued to read on. The more I read, the more I learned that this case just doesn't meet my needs. Aesthetically, it does, but the size restrictions and the optical drive requirements have made it a no-go for me. I decide whether to read a case review based on the "Ooh! Pretty" response. If I get it, I read on. If not, I pass.

    Keep up the good work with the new reviewing process!
  • Dustin Sklavos - Thursday, April 28, 2011 - link

    Thank you for the kind words. I love this case, too, but it just doesn't suit my needs either. Mercifully there's a Raven RV03 in my living room awaiting review...

    ;)
  • james007 - Thursday, April 28, 2011 - link

    If we're going to put together a system around this case, what about that optical drive? You say it has to be a slot-loading slim drive, but.. which ones fit this? You list in your setting simply "Slimline DVD+/-RW Drive" - which one is that?
    I'm also curious to know - are these micro-ATX mobos as overclockable as the full ATX mobos (I was thinking for example of the Asrock Extreme4 for a full-size ATX board, but I like the idea of a smaller package). Otherwise, thanks for creating this excellent review. James Hurst (New Orleans)
