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!

    "While some people may be a little peeved at losing the dual chamber design of the P180 line, I'm not particularly bothered by it."

    I'm not. The dual chambered design is the main reason why I want to get rid of my P182. In my experience, the dual chambers have little effect compared to a standard design, but it makes it twice as difficult to assemble.

    I'm currently looking at new cases right now, and I'm glad that Antec ditched that design.

    I share the same feeling about the dual chamber design (at least on the P182), it's quite a pain to work on the lower chamber, everything is cramped and you have to be extra careful to not let the cables touch the fan that is in-between the hard drives and the PSU.
    If there was a easy way to remove the piece of steel separating both chambers I would do it in a heart beat, the case would be much better then...

    Yep - getting the hard drive cables to not touch the fan can be tricky in the P-182. I still love it, though, just for how quiet it is. I can passively cool my HD4890 using only one case fan (and the hard drive fan) for an almost completely silent system. Glad to see the improvements, though.

    After some time I removed the fan in the lower chamber. I've got only one HDD and the PSU is 80+ Gold (now), so I don't it any more. Still cramped, but much easier.

    I kind of liked my dual chamber 180. It was pain but once my cables were secure it didn't cause any problems.

    Look at the Define XL by Fractal Design.
    I just bought one and it's great. It has two chambers too, but done right without a fan in the way. And it doesn't have the fans in the top so it's quieter - much better as long as you don't want watercooling or manual fan control. I don't.
    The one thing that the Antec has that I want is the double hinged door. Otherwise the Define XL is nicer and it has plenty of cooling with two additional fans. Enough to overclock the heck out of a Bulldozer with a NH-D14 anyway and it's still quiet.

    I've got the Define R3 and it has some issues like hard to close side plate, side plate screws not mounted on the plate itself (like they were on the Antec P150), too small reset button and a bit fiddly cable routing.

    It's not a bad case but not a great one either. Personally I really loved the Antec P150 except it had a poor quality power/reset button (easily breaking plastic) and couldn't fit full length graphics cards without taking a hacksaw to some parts.

    I wonder a little bit about the CPU cooler. Would a cooler with a different configuration work better with some of these cases?

    I understand it's important to keep things consistent across different cases, but I can't help but think that cases that do such a good job of ambient cooling (R3, P280) should have no problem with a CPU that has it's OWN cooler attached to it already. It makes me think the CPU cooler isn't doing it's job properly.

    "It makes me think the CPU cooler isn't doing it's job properly." Or, alternatively, that the case may have been designed with another CPU cooler in mind.
  • Dribble - Tuesday, November 15, 2011 - link

    Looking at the case it looks like cool air comes in at the front + bottom, turns 90 degrees gets heated by the gpu and then probably wants to exit mostly out the top which is blowing accross the cpu a bit. Another design of cooler might take a degree or two off.

    That said the gpu gets lots of cool air, and being as these days that's the hottest thing in the pc you could argue that it's now more important to cool then the cpu.
