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.

    Especially when it's molded like that on the front in. It'd look better and be just as cheap I'd wager with a cleaner design and with a matte finish.

    Hah, that is exactly the first thing I thought when I saw it.

    Then I was dismayed by the sheer number of holes all over it. It would be terrible for keeping quiet.

    Spend a bit more and get yourself a Fractal Design Define R3. Who even wants that many 5.25" bays anyway?

    The only thing I do like about the design on this is the ventilated back panel that extends beyond the 120mm fan and down the side where the graphics card(s) would be.

    That would be nice to let the graphics card breathe a bit more, but it's not on the side, so it's unlikely it would create a path for sound directly to your ear. Fractal Design, take note of that minor point. (I also prefer ports and buttons on the front, and honestly I'd rather have the power button BEHIND the door. Ports collect dust when they're facing up!).

    That said, it's almost certainly made the same OEM that Fractal Design uses. It shares a very high number of case elements, although it's done them in a slightly more half-assed way than the Define case does. Filtered fans, and so on.

    It also looks like it has the same rubber grommets, which are terrible. They're too soft and they fall out of the hole if you so much as breathe on them. The ones that came on the back of my Antec P182 are perfect in comparison, you can jam your finger in, pull it out, and the grommet does not fall out.

    Try that on these or on the Fractal Design cases (like I said, looks like the same OEM), and those things will pop out as soon as you push.

    Fractal Design has fixed that. I built with a Define XL (new model) recently and the grommets stuck where they should.

    ... for the increase in quality their products have been getting recently. Better power supplies, better cases, better Rosewill-branded nose/ear hair trimmers too. But damn, the Ranger is hideous... not in a pseudo-good way, or a quirky way. It's first degree murder with the ugly stick.

    But from a functional point of view, I guess it works. It's just not as sexy as the Lian Li PC A05NB while doing it.

    They still have a long way to go, IMHO.

    And asking $70 for this case is a joke. Don't be surprised if Newegg has it on sale for $40 (or less) soon, just to clear out their inventory. This is a hideous case, and I can't see any serious system builder wanting to use it.

    Oh, and Dustin? There's plenty of sub-$100 cases that look good and perform well. The snobbery that exists for high prices (versus low priced) cases is just ridiculous.
  • Dustin Sklavos - Wednesday, December 14, 2011 - link

    You guys keep accusing me of snobbery when I've spent the last year testing these cases and have a big fat spreadsheet full of results.

    I do have a sub-$50 case review coming up that I was quite fond of, but the reality is that you ARE going to have to spend if you want heavy duty cooling performance with good acoustics.
  • marvdmartian - Wednesday, December 14, 2011 - link

    Sorry, Dustin. Didn't mean to point a finger solely at you, in the case snobbery comment.

    The snobbery seems, instead, to exist in a general way among many computer building enthusiasts. Some places I've seen, it's a prevailing attitude for years now (the whole, "Oh, it's not a Lian Li case"? comment gets old, ya know?).

    I will agree to disagree with you, concerning your cost versus heavy duty cooling and good accoustics point, though. To me, unless it's an HTPC case, I don't worry as much about accoustics (pushing 50 years old, with bad hearing, probably has something to do with that). My previous build was with an Antec 900 case, which offers excellent cooling, and is pretty darn quiet, but pushes the $100 price range. My current build was done in an Antec 100 case, which also offers pretty decent cooling, at half that price......and the only thing I hear from it is the hard drive winding up when it first starts up (sorry, no $$ for an SSD in my near future).

    But computer cases are like cars, and we're all going to have different tastes in what we like. Personally, I'd rather have an inexpensive box, filled with good quality components.
  • Zoomer - Wednesday, January 18, 2012 - link

    Antec 300 for $30 is the hands down value winner. I do have to spend some time adding some time to the side, taping up holes and neutering the top fan. I also took a marker to the blue LED but it's still kinda too bright.

    On the bright side, it is just barely audible beside hdd seek, but that sound is acceptable to me.
  • piroroadkill - Wednesday, December 14, 2011 - link

    Is an extremely bad thing when fitting the case.

    My P182 lacked enough holes and space to route cables efficiently round the back of the case.

    When I took my motherboard out (I was having random issues), I discovered that just the force of putting the case side on had, over time, slowly bent the motherboard tray, and thus the motherboard, which I'm now pretty certain caused my issues.

    I never pushed it on with a lot of force or anything, either. It's a cautionary tale, and a HUGE point against any case when you can't fit things without a real shove.
