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.

    What's the point? For the one person who has a Zalman Reserator still?
    That said, nice enough case, but my go-to case is still the Fractal Design Define R3. It just seems to do everything for everybody (as long as your graphics card fits), in a compact size, and sleek P180-esque design.

    I love watercooling my rig but have never used the water cooling holes on any case.

    Even if I were to use the holes, the positioning on the Antec is just weird. Because the Antec is not too tall you could place a radiator on top of the case with fans actually in the case either pulling cool outside air through the rad and into case or pushing slightly warmer air (not as good but good enough most of the time) from case through radiator and out. Either way you would want the water cooling holes to line up with the inlets on the radiator - and they do not so you would have to mod the top of this case.

    Is a bit of a shame because this could be a nice case to use for watercooling with a 240 radiator in front and on top - need to rip top off and remodel though.

    I guess I will go back to the Arc Midi

    As a regretful former owner of a Zalman Reserator, I find it an obvious fantasy that there still exists even one functional example. I dismembered the over complicated carcass of mine, recycling as much as possible, so that it might never reconstitute itself once again into a worthless beeping nightmare.

    I have a Silverstone TJ08-E and had to cut holes in the back myself (used the place above PCI brackets) because I use an external radiator mounted to the side of the case. A lot of people with high-end water cooling use external radiators with 3x3 120mm/140mm fans and need those holes. So there are good reasons for having them and usually they don't bother those who don't need them. However, here they are unfortunately placed very strangely and viewable. :-/

    I am not a fan of having fan holes behind the motherboard, I used to own a Thermaltake V9, which had such a feature and all it did was allow dust to accumulate on the back of the motherboard.
  • Arbie - Tuesday, January 24, 2012 - link

    A case vent behind the motherboard is actually a good idea. Even if you don't put a fan there, it is one of the few places where a simple hole makes sense. Being shielded from the main cavity, it won't let much noise leak out. But air will find its way, and will circulate around much of the mobo perimeter and rear surface to get there.

    This assumes, of course, that you are running at least a slight positive pressure, which I think is the only sensible thing to do (see other posts). Otherwise you will get dust, as you note.

    I managed to get an original 300 for $30 through a rebate and sale lining up. Didn't need it at the time but figured cases don't go bad. Then USB 3.0 came out :/
  • Taft12 - Tuesday, January 24, 2012 - link

    Cases don't go bad thanks to devices like this!

    How can that supply usb 3.0? it uses a usb 2.0 internal connection...
