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 Antec Neo ECO 620W (included with enclosure)

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.

    I stopped buying a lot of Antec cases because of the power supply mounting. That goofy cross bar makes changing a power supply a real pain, usually requiring the motherboard to be removed.
    If the crossbar was an inch lower or installed with screws, that would be great.

    I still buy other Antec cases though. Ones that are easily serviceable.

    I can honestly say that I've used 100s of Sonata Cases over the years and I am a fairly casual builder (10-40 systems a year) The III had some failure rates on the PSU for a time... and they've always been a bit of a pain to get in and out. The bottom feet were nice until glue gave way and they fell off to.

    I've emailed antec many times to make suggestions for case changes... but minimal stuff. Adding a window that sort of deal. Out of all their cases I think I still like the Super Lan-Boy as it had a similiar design to the Sonata's interior but had alot of polish to it as well. Would love to see a return to that with brushed black aluminum and ever so slight changes. But no.. they have gone gaudy and big of late and are screwing with designs that really worked. It's a shame.

    When the price comes down I will likely start buying the IVs.. although your review sugggests there will be things about it I definitely dont like it's still nice to get a case with an included decent psu for a very reasonable price. (currently its not reasonable though so .. yeah)

    I had two Sonata cases 1 and 3 gen.
    It was a great case. A super silent solution.
    The problem is that for new builds with cards like GTX-570 it's just not enough.
    There is no cable management, Not enough cooling, the PSU is located at upper section of the case and the design is far from real tooless design.
    Antec should reinvent this case.
    Maybe 3 140MM fans and solitude will make a worthy product.
    At the mean time I got a LanCool PC-K62B which is quite silent and has very high finishing quality.
    Anyway, I'll always have sympathy to the Sonata line.

    Learned my lesson with the first 4480-II I bought. It should never have been for sale in 2009. And now this dinosaur. It might as well be a Dell. Antec is coasting on their rep.

    It's a decent case.

    Optical Drive rail instillation is easy, just make sure to use the lower wholes and have the clips point out where the door is.

    The HDD goes in easy as well, and it's easy to plug in. there's some room at the bottom inside right to store the cables for PWR/Reset/HDD Light & front USB/Audio etc.

    The USB3 front cable is a nuisance to deal with while installing it should have been fed under our around the MB back plate.

    The case comes with lots of screws in three different bags & cable ties.

    There are plenty of Power cables with the included power supply and a little bit of space to bundle the left over ones together.

    The fan comes with a male/female molex connector. and works well.

    it can be had for $187AU and would recommend for first time builder on medium budget who wants front USB3, and a nice quiet case.

    Otherwise I would recommend the Lian-Li (Lancool) PC-K57 which also has front USB3, and 2 fans for $98 plus a Silverstone Strider Plus 600W ST60F-P for $99AU, for a total of: $197AU or $10 more. but that gets you a modular PSU,and a case with better cooling.

    Cheers

    Will it not increase HDD wear to store them vertically? All bearings and other movable parts will be stressed much more on one side than on the other.

    More and more motherboards are appearing with the new standard header for front USB 3.0 ports. As USB 3.0 ports are compatible with USB 2.0 connectors, case manufacturers should rush to implement dual front USB 3.0 ports.

    Instead, we are getting only a trickle of cases that are compatible with the new internal header, while it's mostly business as usual for USB 2.0 front ports.

    Plugging a front USB 3.0 port into the back panel was good only as a stopgap while there was no USB 3.0 internal header standard.

    I own a Sonata III, and I'm happy with it. I know that it doesn't feature 'cable management', but Sonata III's design allows ti hide most of the cables behind 5.25" bays and/or 3.5" hard drive bays. I can also route hard disk cables on the back side. Sonata III lacks SSD mounting adapter, but it's still better than Sonata IV, IMO. Sonata IV is using a totally different airflow, forcing users to leave the cables visible.
    About the USB 3 front connector: routing the connector to the back of the case it's not a very good idea. I'd rather build a system with a front USB panel, instead of using this method.
  • TrackSmart - Monday, June 13, 2011 - link

    I partly agree. I love my Sonata III and don't plan to change it anytime soon. It was a great value at the time (1.5 yrs ago) for a classy, quiet case, with a high quality, high efficiency powersupply. But we are halfway into 2011 and the street price is now $130 for the same case i purchased for $100 back then. That's definitely a step in the wrong direction and makes it less of a bargain than it used to be.

    I didn't even bother using the SSD mount on the Sonata IV. I didn't think it was a good idea to bend the SATA connectors that much permanently.
